Failed to create the Crystal Query Engine Visual Studio 2005

When try to open crystal report in VS 2005, error message appear "Failed to open document" and followed by message "Failed to create the Crystal Query Engine".

I believe it same case with what discuss in http://social.msdn.microsoft.com/Forums/en/vscrystalreports/thread/79e1da80-f5c6-42fa-80ca-65a10de5729d .

The root cause maybe because of installation and uninstallation of merge module. Many recommend that we remove the crystal report, after that add crystal report back to visual studio. Steps below

1. Go to Add/Remove Programs and select Change/Remove for Microsoft Visual Studio 2005
2. Select Next then Add or Remove Features from the Visual Studio 2005 Maintenance Mode app
3. Uncheck Crystal Reports for Visual Studio and select Update
4. Once the "Update" is complete, select Finish
5. Go back to Add/Remove Programs and select Change/Remove for Microsoft Visual Studio 2005
6. Select Next then Add or Remove Features from the Visual Studio 2005 Maintenance Mode app
7. Check Crystal Reports for Visual Studio and select Update
8. Insert Disk 1 of Microsoft Visual Studio 2005 Installation CD's and select OK
9. Once the "Update" is complete, select Finish

But in my case, i don't have installation CDs with me. So, i try an alternative way to get it work. You can try it but at your own risk.

I have another development machine which i call it machine B which have VS 2005 with crystal report install and working fine. The one have problem, i call it machine A. What i do is:

1. go to machine B, go to folder C:\Program Files\Common Files\Business Objects\2.7

2. copy the whole bin folder to a external drive or pendrive or thumb drive

3. close the visual studio 2005 in machine A if it's open

4. go to machine A, go to folder C:\Program Files\Common Files\Business Objects\2.7 and rename the bin folder to binA for backup purposes

5. copy the bin for the external drive to C:\Program Files\Common Files\Business Objects\2.7 in machine A

6. try to open visual studio 2005 and open the crystal report development file.

7. it working

It solve my problem especially when i don't have the installation cds with me at the moment. Hope this help

Ping 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

Method not found: 'Void System.Web.UI.ScriptManager.RegisterStartupScript

Deploy a running web application from one windows 2003 server to another windows 2003 server. The application is running asp.net 2.0 framework with Ajax.net v1, MSSQL 2005.

After deploy everything and run the application, Error message

Method not found: 'Void System.Web.UI.ScriptManager.RegisterStartupScript(System.Web.UI.Page, System.Type, System.String, System.String, Boolean)'

Situation:

In the bin folder, we deploy together with

AjaxControlToolkit.dll

AjaxControlToolkit.pdb

System.Web.Extensions.Design.dll

System.Web.Extensions.dll

After look around and found that the server already installed with the same version but the strange thing is the file size are different from the one i have in bin folder. The first thing can thought of is reinstall the ajax.net.

No luck, after the ajax.net reinstallation, it's not work. Still the same error message:

Method not found: 'Void System.Web.UI.ScriptManager.RegisterStartupScript(System.Web.UI.Page, System.Type, System.String, System.String, Boolean)'

Try to delete all 4 dlls

AjaxControlToolkit.dll

AjaxControlToolkit.pdb

System.Web.Extensions.Design.dll

System.Web.Extensions.dll

from the bin folder but still same error show. So, i undo the deletion.

Try to google around and look for useful suggestion but no luck. All post stated that working after the ajax.net re installation.

Finally, i uninstall the ajax.net from the server and let the application use the 4 dlls

AjaxControlToolkit.dll

AjaxControlToolkit.pdb

System.Web.Extensions.Design.dll

System.Web.Extensions.dll

in the bin files.

It solve my problem.

Hope this sharing helps.

PHP: Warning: split() [function.split]: REG_EMPTY in xxx

I try to php split to split out the concatenated data. Below are the sample that i use

$comp = "V1001|VI003";

$comp_arr = split("|",$comp);

i hit error:

PHP: Warning: split() [function.split]: REG_EMPTY in xxx

after search around and found that the issue is caused by symbol "|".

"|" is an operator in PHP. If want to use the this symbol as a delimiter, we must excape it with a back slash, "\|"

now it become

$comp = "V1001|VI003";

$comp_arr = split("\|",$comp);

and it works.

Hope this help

odbc: data source name not found

Situation:

The application written in ASP with dll and etc and use ODBC for database connection. Everything working fine but one day there was a auto windows update can cause this ASP application running with error message "data source name not found". Plenty of time taken for debugging and not solved. Finally by trial and error, the problem solved. Strange, the problem is caused by the permission setting on the dll which call the ODBC. We suspect the problem cause by the windows update and change the permission setting.

Hope this help.

phpsoap: retrieve returned array data

Well, i'm newbie in soap especially phpsoap. I'm facing problem to retrieve data returned from a soap api written in .net. I can see the whole data printed out by using print_r but i'm not able to get the each data from the array returned.

Situation:

I want to get the data returned by the soap server in array form after i've called the function "GetAccountInfo" by passing in parameter "AccoundID" by using phpsoap client.

My soap server url: http://10.10.100.101/soapserver.asmx

below are the code that i can get the data printed out.

<?php

$ini = ini_set("soap.wsdl_cache_enabled","0");

//instantiate the SOAP client

$client = new SoapClient("http://10.10.100.101/soapserver.asmx?WSDL");

$params = array();

$params["AccountID"] = "inblues";

$result = $client->GetAccountInfo($params);

print_r ($result ->GetAccountInfoResult);

?>

Output on the browser:

---

Array (

[GetAccountInfoResult] => Array (

[memberData] => Array (

[lastlogin] => 6/19/2009 2:10:51 AM

[lastip] => 219.95.192.254

[datecreated] => 6/19/2009 2:10:51 AM

[active] => 1

)

)

)

---

But what i want is only [active] field's data. What can i do? Finally, by looking at the printed result and by try and error, i found out that it's a 3 dimensional array, below code helps me to get the data i want.

<?php

$ini = ini_set("soap.wsdl_cache_enabled","0");

//instantiate the SOAP client

$client = new SoapClient("http://10.10.100.101/soapserver.asmx?WSDL");

$params = array();

$params["AccountID"] = "inblues";

$result = $client->GetAccountInfo($params);

// the result is in 3 dimensional array

print_r ($result->GetAccountInfoResult->memberData-> active);

?>

Solve. I get my value 1 printed out in the browser.

phpmyadmin and stored procedure

As far as i know, we are not able to view, edit stored procedure using phpmyadmin but we are able to drop/create stored procedure using phpmyadmin.

I try to create a mysql stored procedure using phpmyadmin and hit error below

Error

SQL query:

DELIMITER;

MySQL said:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER' at line 1

my original code:

DELIMITER $$

DROP PROCEDURE IF EXISTS `xxxweb`.`pp_pspbatch` $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `pp_pspbatch`(
IN pBatchName VARCHAR(255),
IN pCountryID INT
)
BEGIN

DELIMITER ;

try below steps, it help to solve my problem
1. Go to any SQL tab in phpMyAdmin.
2. Directly below the SQL text area you'll see a text input labeled "Delimiter." In that field, enter "$$".

3. Modify the script become like below

DROP PROCEDURE IF EXISTS `xxxweb`.`pp_pspbatch` $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `pp_pspbatch`(
IN pBatchName VARCHAR(255),
IN pCountryID INT

SmarterMail not receiving mails but can send out email

Well, set up my smartermail in new windows 2003 server. I've already make sure steps provided in Smartermail help file properly set.

WebMail URL (A Record) - Add an A or CNAME record for mail.example.com that points to the IP address of the webmail interface. This will allow users of that domain to access the webmail by typing in http://mail.example.com or http://mail.example.com:9998 in their web browser (depending on whether you use the included web server or IIS).

Mail Pointer (MX Record) - Add an MX record for example.com that points to the IP address that you assigned when adding the domain to SmarterMail. This will allow other email servers to locate your mail server.

Reverse DNS Record - Add a reverse DNS record for IP addresses assigned on the server to provide extra assurance to other mail servers. Also, it is recommended that the primary IP address of the server also have a reverse DNS record. Note: Adding reverse DNS may also require a change at your isp.

Also already setup iis to able login thru specific domain. Things work fine, able to send out email but not able to received email from external domain that not in the server. Strange, huh?

After check here and there, finally find out that we need to enable port in windows firewall.

Well, open my windows firewall and add in "Exceptions" to the port correctly. For my case, i just enable the port for below port

It's work. Hope can help.

PHP call external cgi and process responses

This is tough for me. First time to code in PHP with cgi and don't know how to start. Thanks google for this.

My task is call a cgi script to execute some function and process the return data. Well, here i'll mention on how to call external cgi and the process part can be settled using PHP string processing.

Let's start by example:

cgi domain location: www.xincube.com/script/handler/api.cgi

The code will strip header below and return the content of the response data.

HTTP/1.1 200 OK
Date: Sat, 06 Jun 2009 02:23:33 GMT
Server: Apache
Proxy-x-forwarded-for: 203.116.10.206
X-returncode: 0
X-returndesc: Access denied
Cache-control: no-cache
Pragma: no-cache
Connection: close
Transfer-Encoding: chunked
Content-Type: text/plain

We can do anything we want to get the information we need in $content.

CODE:

/* sample for calling cgi */

$host = 'www.xincube.com';

$path = '/scripts/handler/API.cgi';

$data_to_send = 'action=GetSupportedData';

PostToHost($host, $path, $data_to_send);

/* function that will call cgi */

function PostToHost($host, $path, $data_to_send) {

$header = "not yet";

$content = '';

$fp = fsockopen($host,80, $errno, $errstr, 30);

if (!$fp) {

echo "$errstr ($errno)\n";

}

else {

fputs($fp, "POST $path HTTP/1.1\n");

fputs($fp, "Host: $host\n");

fputs($fp, "Content-type: application/x-www-form-urlencoded\n");

fputs($fp, "Content-length: ".strlen($data_to_send)."\n");

fputs($fp, "Connection: close\n\n");

fputs($fp, $data_to_send);

while(!feof($fp)) {

//echo fgets($fp, 4000);

$line = fgets( $fp, 4000 );

if( $line == "\r\n" && $header == "not yet" ) {

$header = "passed";

}

if( $header == "passed" ) {

$content .= $line;

}

}

echo $content;

fclose($fp);

}

}

MySql.Data.MySqlClient.MySqlException: Table 'xxx.xx_XxxxXxx' doesn't exist

Hit error when try to connect to MySQL in Linux from ASP.NET in IIS6. Seriously, the table is 100% Exist in the database but i hit error below:

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: MySql.Data.MySqlClient.MySqlException: Table 'xxx. xx_XxxxXxx' doesn't exist

Well, finally find out that it caused by case sensitive on the table name. After i've change the name, it's work perfectly.

Access denied for user 'xxxx'@'xxx.xxx.xxx.xxx' (using password: YES)

Well, my scenario is connecting my ASP.NET 2.0 apps from IIS6 (window 2003 server) to MySQL (Linux) using ADO.NET Connector.

Hit error message when try to connect:
Access denied for user 'userxxx'@'xxx.xxx.xxx.xxx' (using password: YES)



It's quite worry because this is first time trying to connect from a .net web application is IIS to MySQL in Linux.

Prior to that, privileges must be granted in MySQL.
______________________________________________
mysql> grant all privileges on *.* to 'userxxx'@'xxx.xxx.xxx.xxx'
identified by 'xxxpasswordxxx' with grant option;
Query OK, 0 rows affected (0.00 sec)
______________________________________________

Finally, found that it's my own mistake. I've put in the wrong username and password. Check your username and password seriously before the connection.

Add more than one column to a table in MySQL

Sometimes we might need to add multiple column to a table in MySQL, sample below work perfectly

ALTER TABLE pp_batch_detail
ADD `user_id` int(10) unsigned default NULL,
ADD `user_name` varchar(255) default NULL,
ADD `date_request` datetime default NULL;

Develop application using SQL Compact 3.5 SP1 with Visual Studio 2005

Can MS SQL Compact 3.5 SP1 work together with VS 2005? The answer is yes.

We are using Visual Studio 2005 (C#) and wish to create a window desktop application. After some consideration, the decision is for for MS SQL Compact 3.5 SP1.

Dynamic Image in Crystal Report 9 Visual Studio 2005 - C#

I found many developers facing the same problem as i do - dynamic include image to crystal report with Visual Studio 2005 . This is how we solve our problem in C# when developing a desktop window application.

1. In your xsd, create a colomn that does not exist in your dataset, example, [LogoImage], and set the datatype to “System.Byte[]”. You might find the datatype option only have “System.Byte”, you can manually type in “[]”.
   
2. Add the following code in your form.
   
   private void AddImageColumn(DataTable objDataTable, string strFieldName)
   {
   try
   {
   DataColumn objDataColumn = new DataColumn(strFieldName,
   Type.GetType("System.Byte[]"));
   objDataTable.Columns.Add(objDataColumn);
   }
   catch (Exception ex)
   {
   //handler
   }
   }
   
   private void LoadImage(DataRow objDataRow, string strImageField, string FilePath)
   {
   try
   {
   FileStream fs = new FileStream(FilePath, System.IO.FileMode.Open,
   System.IO.FileAccess.Read);
   byte[] Image = new byte[fs.Length];
   fs.Read(Image, 0, Convert.ToInt32(fs.Length));
   fs.Close();
   objDataRow[strImageField] = Image;
   }
   catch (Exception ex)
   {
   //Handler
   }
   }
   
   
3. After your getting your dataset from database and before bind to the report view, do this.
   
   AddImageColumn(myDataTable, "LogoImage");
   
   for (int index = 0; index < myDataTable.Rows.Count; index++)
   {
   if (myDataTable.Rows[index]["LogoLocation"].ToString() != "")
   {
   if(File.Exists(myDataTable.Rows[index]["LogoLocation"].ToString()))
   {
   LoadImage(myDataTable.Rows[index], "LogoImage",
   myDataTable.Rows[index]["LogoLocation"].ToString());
   }
   else
   {
   LoadImage(myDataTable.Rows[index], "LogoImage",
   "C:\\NoImage.jpg");
   }
   }
   else
   {
   LoadImage(myDataTable.Rows[index], "LogoImage", "C:\\NoImage.jpg");

Installation SQL 2008 Express Error: '' is not a valid login or you do not have permission

This is a very strange error. I've received error message "'' is not a valid login or you do not have permission" when trying to install Microsoft SQL Server 2008 Express Edition in my Microsoft XP Pro SP3 Machine.

To know more on installation guide, please check Install and Configure SQL Server 2008 Express by CondorMan.

I've followed the steps and got error message "'' is not a valid login or you do not have permission." and print screen as below.



I have no idea why is this. I've tried few suggestion stated in some of the forum:

1. I've tried to change my user name and try to install.
2. Create a new user "sa" with strong password. Login to window using this account and do installation.

Both methods fail.

Finally, i try to rename my machine/computer name and try to install and the installation completed successfully.




Conclusion:
This may be a bug from microsoft but i'm not sure.

My scenario: computer name = my user account

My Solution: change computer name to != user account then do installation.

p/s: Change user account won't help.

Hope this can help you. Share your solution if you have different one.

   Crystal_Database_Access2003.msm
   Crystal_Database_Access2003_enu.msm
   Crystal_Managed2003.msm
