MS SQL profiler like for mysql

I was looking around a software for MySQL that can work like MSSQL profiler which can monitor the SQL query executed. Finally i found one called Log Monitor which work well for me.


How it's work? Download Log Monitor. Open LogMonitor.jar file.


Connect to MySQL server, open a SQL Query window and run this script



SET GLOBAL general_log = 'ON';



Check on log file location in my.ini file (for windows user) or my.cnf (for linux user).

For windows user,
#Path to the database root
datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.1/Data/"

Open Log Monitor and set "log file path" with the file name. 




Now, open another SQL Query window and run any script. You can see the query you run displayed in the Log Monitor.



Hope this help.

Keep track download in ASP.NET

Situation:
I have a software in my web server and let visitor download for free, i wish to keep track of total download and visitor location. 

Feasibility:
For the location keep tracking, i use GeoIP (GeoLiteCity.dat) http://www.maxmind.com/app/ip-location 

Solution:

Database:
I have create a table called downloadlog with field below. I plan to have different type of product in future, so i add ProductFamilyID field. If you don't have that, you can ignore it.















Now, i need a stored procedure called psp_DownloadLog_Add that insert data into table above. The code should be as simple as possible



CREATE PROCEDURE [dbo].[psp_DownloadLog_Add]
(
@p_IP NVARCHAR(50),
@p_Country NVARCHAR(255),
@p_CountryCode VARCHAR(50),
@p_City NVARCHAR(255),
@p_ReferrerURL        NVARCHAR(512),
@p_ProductFamilyID INT
)
AS
BEGIN
SET NOCOUNT ON;

INSERT INTO tblDownloadLog
(
IP,
Country,
CountryCode,
City,
ProductFamilyID,
ReferrerURL,
DownloadDate
)
VALUES
(
@p_IP,
@p_Country,
@p_CountryCode,
@p_City,
@p_ProductFamilyID,
@p_ReferrerURL,
GETDATE()
)

SET NOCOUNT OFF;

END

ASP.NET

To make the system more structural and manageable, I have create 2 classes to handle the download log. DownloadLogInfo class mainly is use the deal with the information that need to log into database. DownloadLog class is mainly the class who do the communication with the database. Please check the code below.

DownloadLogInfo class



 public sealed class DownloadLogInfo
    {
         public DownloadLogInfo() { }
        
         int _downloadID = 0;
         string _ip = "";
         string _country = "";
         string _countryCode = "";
         string _city = "";
         int _productFamilyID = 0;
         string _referrerURL = "";
         DateTime _downloadDate = DateTime.Now;


         public int DownloadID { get { return _downloadID; } set { _downloadID = value; } }
         public string IP { get { return _ip; } set { _ip = value; } }
         public string Country { get { return _country; } set { _country = value; } }
         public string CountryCode { get { return _countryCode; } set { _countryCode = value; } }
         public string City { get { return _city; } set { _city = value; } }
         public int ProductFamilyID { get { return _productFamilyID; } set { _productFamilyID = value; } }
         public string ReferrerURL { get { return _referrerURL; } set { _referrerURL = value; } }
         public DateTime DownloadDate { get { return _downloadDate; } set { _downloadDate = value; } }

         public DownloadLogInfo(int pDownloadID, string pIP, string pCountry, string pCountryCode, string pCity, int pProductFamilyID, string pReferrerURL, DateTime pDownloadDate)
         {
             _downloadID = pDownloadID;
             _ip = pIP;
             _country = pCountry;
             _countryCode = pCountryCode;
             _city = pCity;
             _productFamilyID = pProductFamilyID;
             _referrerURL = pReferrerURL;
             _downloadDate = pDownloadDate;

         }


    }

DownloadLog Class

    public sealed class DownloadLog
    {
        public void Add(DownloadLogInfo pInfo, string pConnectionString)
        {
            SpParamInfo[] myParamInfo = new SpParamInfo[6];
            myParamInfo[0] = new SpParamInfo("@p_IP", SqlDbType.NVarChar, pInfo.IP);
            myParamInfo[1] = new SpParamInfo("@p_Country", SqlDbType.NVarChar, pInfo.Country);
            myParamInfo[2] = new SpParamInfo("@p_CountryCode", SqlDbType.NVarChar, pInfo.CountryCode);
            myParamInfo[3] = new SpParamInfo("@p_City", SqlDbType.NVarChar, pInfo.City);
            myParamInfo[4] = new SpParamInfo("@p_ProductFamilyID", SqlDbType.Int, pInfo.ProductFamilyID);
            myParamInfo[5] = new SpParamInfo("@p_ReferrerURL", SqlDbType.NVarChar, pInfo.ReferrerURL);

            DbAdapter myDbAdapter = new DbAdapter(pConnectionString);
            myDbAdapter.ExecuteNonQuery("psp_DownloadLog_Add", myParamInfo);

            myDbAdapter.Dispose();

        }

    }

Now, I have create a page, call download.aspx. This page will actually get information from the visitor and insert into database. After that it will force a file to be downloaded. Before that, i already GeoLiteCity.dat file and put into my App_Data folder.


Code behind for download.aspx


protected void Page_Load(object sender, EventArgs e)
    {
        string VisitorReferrer;

        // Full path to GeoLiteCity.dat file
        string FullDBPath = Server.MapPath("~/App_Data/GeoLiteCity.dat");
        // Visitor's IP address
        string VisitorIP; 
            
        VisitorIP  = Request.ServerVariables["REMOTE_ADDR"];
      
        if (Request.UrlReferrer != null)
        {
            VisitorReferrer = Request.UrlReferrer.ToString();
        }
        else
        {
            VisitorReferrer = "";
        }

        // Create objects needed for geo targeting
        Geotargeting.LookupService ls = new Geotargeting.LookupService(FullDBPath, Geotargeting.LookupService.GEOIP_STANDARD);
        Geotargeting.Location visitorLocation = ls.getLocation(VisitorIP);
        
        DownloadLog myDownloadLog = new DownloadLog();
        DownloadLogInfo myDownloadLogInfo = new DownloadLogInfo();


        if (visitorLocation != null) // get the geoip information using visitor IP address
        {
            myDownloadLogInfo.Country = visitorLocation.countryName;
            myDownloadLogInfo.CountryCode = visitorLocation.countryCode;
            myDownloadLogInfo.City = "unknown";
            if (visitorLocation.city != null)
            {
                myDownloadLogInfo.City = visitorLocation.city;
            }
            
            myDownloadLogInfo.IP = VisitorIP;
            myDownloadLogInfo.ProductFamilyID = 1;
            myDownloadLogInfo.ReferrerURL = VisitorReferrer;
        }
        else
        {
            string country = "unknown";
            string countryCode = "unknown";
            string city = "unknown";
            myDownloadLogInfo.Country = country;
            myDownloadLogInfo.CountryCode = countryCode;
            myDownloadLogInfo.City = city;
            myDownloadLogInfo.IP = VisitorIP;
            myDownloadLogInfo.ProductFamilyID = 1;
            myDownloadLogInfo.ReferrerURL = VisitorReferrer;
        }

       
       // WebConfig.Connection is the connection the database and insert data into database
       myDownloadLog.Add(myDownloadLogInfo, WebConfig.Connection);
        
       Response.ContentType = "application/zip";
       Response.AddHeader("content-disposition", "attachment; filename=softwaresetup.zip");

       FileStream sourceFile = new FileStream(@"C:\inetpub\dotnetfish\software\softwaresetup.zip", FileMode.Open);
        
       long FileSize;
       FileSize = sourceFile.Length;
       byte[] getContent = new byte[(int)FileSize];
       sourceFile.Read(getContent, 0, (int)sourceFile.Length);
       sourceFile.Close();

       Response.BinaryWrite(getContent);

Convert CString to std::string and vice versa

// convert from std:string to CString
CString errorMsg'
std::string encodeError = "Error 01";
errorMsg = CString(encodeError.c_str());



// convert from CString to std:string
CString csData = "f1db14dfa5d54f0b";
std::string ssData((LPCTSTR)csData);

Convert CString to char array

Again, when use CString, remember to include afxwin.h

char csRoom [20];
BSTR sRoom = "102";

CString myString1(sRoom);
strcpy(csRoom,myString1);

now, value from CString copied to char array

Convert BSTR to CString

When use CString, remember to include afxwin.h in your header.

BSTR sComPortNumber = "COM1";

//declare CString csComPortNumber and convert BSTR cComPortNumber to CString

CString csComPortNumber(sComPortNumber);

DONE.

Version Information: Microsoft .NET Framework

________________________________________________________

Solution:
For my case, the reason hit above error is because.NET Framework was installed before IIS server. To solve the problem, register .NET framework to IIS will do.

How to do that? (please be aware that the sample using for.NET Framework V1.0)

Steps:

1. Click on Start -> Run






2. Type in cmd and click OK





3. Command prompt screen will appear. go to"C:\Windows\Microsoft.NET\Framework\
v2.0.50727" folder by using command cd C:\Windows\Microsoft.NET\Framework\v2.0.50727 and hit enter. Please refer screen below:





4. Type in
aspnet_regiis -i and hit enter.




5. Screen below will be shown and dotnet user installed.




aspnet_regiis -i

alternatively you can copy and paste this command into windows command prompt

%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

Ping a port

Well, sometimes we need to know whether the port in open or block, we need to do some checking or troubleshoot through ping/telnet. We cannot ping a IP with port but we can telnet certain IP together with Port no.

For example:
Go to open command prompt, if we want to check whether port 21 is working for IP 203.166.87.9 what we need to do is
> telnet 203.166.87.9 21

please tell me it's work. thanks

Could not load file or assembly 'CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependenci

Deploy a web application that uses crystal report basic 10.5 and hit below error when try to access to the application.

"Could not load file or assembly 'CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The system cannot find the file specified."

This is because we dont have crystal report basic runtime installed in the server.

Where do I get the basic (10.5) runtime? It's on your machine:
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\CrystalReports10_5

My server is a 32 bit machine, so i install CRRedist2008_x86.msi in the machine.

Now what? I still can the same error? Wait, we need to restart the IIS to make it work. After restart the IIS, it's work perfectly.

STOP: c000021a (Fatal System error) The windows subsystem system process terminated unexpectedly with a status 0xc0000005

I hit below error/blue screen when trying to install MSSQL 2005 Express in a Microsoft XP pro SP2 machine:

STOP: c000021a (Fatal System error)
The windows subsystem system process terminated unexpectedly with a status 0xc0000005 (0x7c9106c3 0x0053ec24)

Try for 3 times to reinstall windows and no luck. Hit the same error when installing MSSQL 2005 Express.

Finally found an forum
http://blogs.msdn.com/petersad/archive/2009/01/20/sql-server-2005-sp3-sql-server-2005-sp2-cus-or-sql-server-2008-may-cause-xp-sp2-to-restart.aspx

And hotfix in http://support.microsoft.com/kb/943232

We have to register our email and the hotfix link come with password with send to our email.

After apply both hotfix. My problem solved.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path 'C:\xxx\aa.xml' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Either the Crystal Reports registry key permissions are insufficient or the Crystal Reports runtime is not installed correctly.

Received an error message on my windows desktop application (own developed) after install in a windows 7 64 bit (x64) machine.

____________________________________________
An error has occurred while attempting to load the Crystal Reports runtime.

Either the Crystal Reports registry key permissions are insufficient or the Crystal Reports runtime is not installed correctly.

Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required. Please go to http://www.businessobjects.com/support for more information.
____________________________________________


We already follow the steps suggested:
When compiling the application in Visual Studio .NET 2008 you will need to force it to 32 bit mode.
You can do this by right-clicking the project name in the Solution Explorer and select Properties.
For VB.NET
Click Compile, then Advanced Compile Options. For the Target CPU drop down box, change it from "AnyCPU" to "x86" then click OK.
For C#.NET
Click Build and change the Platform Target option from "Any CPU" to "x86".
You should then be able to run the application on a 64 bit OS without error.

But it still show the same error

___________________________________________
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.TypeInitializationException: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception. ---> CrystalDecisions.CrystalReports.Engine.LoadSaveReportException: An error has occurred while attempting to load the Crystal Reports runtime.

SQL query and optimization

I've run a simple test on sql query involve 2 tables, tblEmail & tblEmailPromotion

Table columns:
tblEmail (email varchar(255), IsDeleted int)
tblEmailPromotion (email varchar(255), PromotionID int)

Both tables without index

SELECT TOP (90) e.Email FROM tblEmail e
LEFT OUTER JOIN tblPromotionEmail pe ON e.Email = pe.Email AND pe.PromotionID = 6
WHERE pe.PromotionID IS NULL
AND e.IsDeleted = 0
AND e.Email LIKE '%hotmail%'
ORDER BY e.Email

It takes about 2:43 (2 minutes 43 seconds) to get the result

Change the question from "LEFT OUTER JOIN" to "IN" become

SELECT TOP (90) e.Email FROM tblEmail e
WHERE e.Email NOT IN (SELECT Email FROM tblPromotionEmail pe WHERE pe.PromotionID = 6)
AND e.IsDeleted = 0
AND e.Email LIKE '%hotmail%'
ORDER BY e.Email

Guest what? great improvement. Takes 1:07 (1 minute 7 seconds) to load the result.

Now, we index table tblEmail column Email (Unique)

SELECT TOP (90) e.Email FROM tblEmail e
LEFT OUTER JOIN tblPromotionEmail pe ON e.Email = pe.Email AND pe.PromotionID = 6
WHERE pe.PromotionID IS NULL
AND e.IsDeleted = 0
AND e.Email LIKE '%hotmail%'
ORDER BY e.Email

It takes about 1:22 (1 minute 22 seconds) to get the result

Now, we run the 2nd query:

SELECT TOP (90) e.Email FROM tblEmail e
WHERE e.Email NOT IN (SELECT Email FROM tblPromotionEmail pe WHERE pe.PromotionID = 6)
AND e.IsDeleted = 0
AND e.Email LIKE '%hotmail%'
ORDER BY e.Email

It only takes 27 Seconds

To make the 2nd query better:

SELECT TOP (90) e.Email FROM tblEmail e
WHERE e.Email NOT IN (SELECT Email FROM tblPromotionEmail pe WHERE pe.PromotionID = 6 AND pe.Email LIKE '%hotmail%')
AND e.IsDeleted = 0
AND e.Email LIKE '%hotmail%'
ORDER BY e.Email

This will give 15 seconds.

Summary:

We need to choose the query wisely.
Index will help to improve data retrieving process but must be careful with indexes. Wrong indexes may cause you more problem.

Invoice Software

Recently have downloaded and tested on a few invoice software/invoice system. Some are very complicated, some are not user friendly and some are very old design.

Surprisingly i found a very simple with very attractive user interface invoicing software. It can easily generate a quite professional quotation and invoice. It include delivery note as well but i'm not using it. It come with professional invoice template and we can customize the quotations & invoices's template field and wording and also can upload company logo.

It's very user friendly and the search feature is also very simple. Just nice customer maintenance module, and reporting module.

For the paid version, a very simple inventory module included in the software. Payment receive module and revenue reporting module. One thing want to highlight here is that the reports can drill down to more details level. Love it.

Simple and nice with very low price. Maybe you can try it. The software called Xin Invoice. The support is not bad and also there are some simple demo can find on their web and youtube. It's just suit my needs but i'm not sure for those who is running more complicated business.
