Re: Java script using windows form

5-Dec-07 17:58

I have also faced the same situation i solved this by calling
Page_ClientValidate() function before printing. Don't directly call
window.print() instead

<br />
<br />
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
StringBuilder myScript = new StringBuilder();<br />
<br />
myScript.Append("<script language='Javascript'>");<br />
myScript.Append(" function PrintForm(){");<br />
myScript.Append(" if (Page_ClientValidate()){");<br />
myScript.Append(" window.print();}");<br />
myScript.Append("}");<br />
myScript.Append("</script>");<br />
<br />
this.RegisterStartupScript("MyScript", myScript.ToString());<br />
<br />
Button2.Attributes.Add("onclick","javascript:PrintForm();");<br />
}<br />
<br />

this should help.

A tiny issue with ".NET Snap To Screen Form"

Hi,

The code here is working very good when the ForBorderStyle is NOT set to "None":

http://www.codeproject.com/KB/vb/SnapForm.aspx

In my application, it's set to None... And I move the form by holding down the right mouse button and moving it. The code still partially work, but when I approach the taskbar from the clock side it's not completely sticked to the corners.

I tried to figure out what wrong with code but no luck (and no experience).

The complete code is attached. Just create a new project and paste it.

Your help would be greatly appreciated.

It's not datagrid, there has a control called PropertyGrid.

I believe the SelectionStart property stores where the caret is, if there's no selection.

* In a zip file
* In a self extracting zip file
* As an MSI file
* as a link to a download

A lot of corporate mail systems will block attachments that it sees as dangerous. So EXEs and MSI files prossibly won't get through. ZIP files are also often searched by email scanners so if those files are found in there also it will get blocked.

Well, I see, but every time I send, it always says I'm missing files (or, the other person sees that...). So is there anything I need to include?

Well, your first step would be to make sure the person on the other end has DirectX and .NET installed. Then zip up the files from the directory where you run them ( so they are in the right folders ), rename the zip to zip1 or something if need be ( to avoid it being rejected ) and send

I am writing an HR application to add new employees. Currently, I am having an issue where I want to send a specific message base on the exception that is received. In my database SNN is a unique key hence if an SSN is being added that already exist in the DB a Unique key violation exception is thrown. If the UserID already exist a Primary Key violation exception is thrown. I am certain this is possible but just not sure what is best practice. I can write a method which search the DB first and if the record is found thrown an error message based on whether it was the Unique key violation or the PK violation. I have also been searching MSDN to see if I can identify the C# SqlClient error ID for either scenarios and based on the exception ID, alert the user with the right error message.

Any advice will be greatly appreciated.

All the Ids can be found in SQL Server itself.

Use IF Exists in a trigger and then throw custom exceptions from the sp. However, SQL server will natively through the message number so there is no reason for custom handling to catch it.

This worked perfectly!!!

IF EXISTS
(SELECT Emp_Login_ID FROM Employees where Emp_Login_ID = @Emp_Login_ID )
RETURN -1

ELSE

IF EXISTS
(SELECT Emp_SSN FROM Employees where Emp_SSN = @Emp_SSN )
RETURN -2

ELSE
INSERT INTO........

I am no longer receiving the Exception. However, I am not sure how to throw the Error message in C#. How would C# know to throw and Exception if the insert does nto execute? Thanks for you help.

Note: All this is done in a single stored procedure. Which is then called in the application in a try, catch statement.

Thanks for the help guys. I got it working with the following lines of code. I will simplify my code later but just need to get it working.

SqlParameter paramReturnValue = new SqlParameter();
paramReturnValue.ParameterName = "@return_value";
paramReturnValue.SqlDbType = SqlDbType.Int;
paramReturnValue.Direction = ParameterDirection.ReturnValue;

cmd.Parameters.Add(paramReturnValue);
