Hi All,
I am getting this error when I am adding user control in the form, Please me in solving this problem.
Thanks in advance.

In your user control there is a variable called emSize,
-- Either you are setting the value as 0 (and it should not be)
-- OR there is some calculation going on in the code, which is resulting the value of emSize to be 0 (which ofcourse should not be)
If that does not help, post it the usercontrol code.
Cheers.

No I have not use emSize variable anywhere.
The user controls is date control and code is:
Me.BackColor = g_FormBackColor
Dim obj As Object
For Each obj In Me.Controls
If TypeOf obj Is TextBox Then
obj.backcolor = g_TxtBackColor 'clrtxtbackcolor 'color.lightgray
obj.forecolor = g_TxtForeColor 'clrtxtforecolor 'color.blue
obj.font = New Font(g_strTxtFontName, g_intTxtFontSize, FontStyle.Regular) '"courier new"
'obj.borderstyle = borderstyle.fixedsingle
End If
If TypeOf obj Is Label Then
obj.font = New Font("", g_intLblFontSize, FontStyle.Bold)
End If
Next
My code is working fine if I comment this code.
Please help me...Thanks in advance...

Hi,
I did a quick search, looks like emSize has to do with System.Single, U are right.
don't know the exact reason why the code is falling over, but you can find a way out for sure.
may be 'obj.borderstyle = borderstyle.fixedsingle is the reason.
goodluck

Hi,
in your Font constructor the second parameter (your g_intTxtFontSize) specifies
the "emSize" of the font. Give it a reasonable value before instantiating a
font with it.

When service process exe I am getting Database (Sql Server 2005) error "login failed to user sa.."

Process p;
string FilePath = @"C:\vb_file.exe "; // vb_file connects to DB Sql Server 2005
string arg = " /send";
p = Process.Start(FilePath, arg);
Error I am getting...
The VB Application identified by the event source logged this Application vb_file: Thread ID: 5748 ,Logged:
vb_file Rev. 30-Apr-03T /send /RESTART
vb_file Rev. 30-Apr-03T /send /RESTART

Don't use TxtSpeak. It makes your posts difficult to read. You've got a full 101+ keyboard in front of you, use it.

From the error message, it looks like your "vb_file.exe" used the wrong user name and password in its connection string to contact the database.

Thanks for reply...
Vb_file.exe is using correct username and password, it is using systemdsn to connect Database.
If I open start -> Run and type C:\vb_file.exe /send it is working fine and displaying GUI... and I checked in Event Viewer -> Application log it was not displaying any error.
same thing I am doing in Windows service written in C#..
My Intention is just display VB Application GUI through Windows Service...VB Application is connecting to DB using SystemDSN
Code I am written..
Process p;
string FilePath = @"C:\vb_file.exe ";
string arg = " /send";
p = Process.Start(FilePath, arg);
Service Interactiing with Desktop option is selected...
Once I started service and checked Event Viewer -> Application log ..it is showing below error...
Event Type: Error
Event Source: VBRuntime
Event Category: None
Event ID: 1
Date: 7/13/2007
Time: 9:33:41 AM
User: N/A

Please let me know if you need further info..
Thanks in advance

Why, oh God, WHY does anyone insist on using a DSN?? It's competely useless in today's environment!
It's using the correct username and password to login to the database, huh? Then explain this message to me:
Login failed for user 'sa'.
It's most assuredly NOT using the correct username and password to connect to the database. Scrap the DSN, you do NOT need it, and use the correct connection string in your VB code. Since you'll be running this from a Windows Service, you can NOT use the "Trusted Connection" option in your connection string.

Hi Dave,

any ways Thanks for info that "you can NOT use the "Trusted Connection" option in your connection string"
Thanks

Hi,
I want to develop project which need to reconigze finger image from nitgen fingerkey hamster

First of all, this is not a 'give me all the code' site. Google is the site you need to try to find existing articles to do what you want.
Second, if you have a finger print reader, it should provide the APIs to do that, you shouldn't need to have to write them yourself.

How to pass multiple values from one form to another via URL ?
|
|
|
|

you can use querystring with multiple parameters to pass multiple values to other page...like....
Response.Redirect(page.aspx?Orderid=" & Orderid "&ProductID=" & ProductID)

This is the windows forms board, how is it yuo want to pass stuff via a URL ?
If the data is stored in the DB already, you can just pass an Id to get it from the DB. You can also do cross page postback in .NET 2.0, or you can use the URL, as someone has already said.
There's also the session, but that would be my last port of call.

Hi,
I am working on a custom UserControl that needs to AutoSize itself to fit it's contents.
It doesn't use any of the traditional Text, Font, Other Controls, etc and all the content generation is done with GDI+
I am overriding GetPreferredSize to return the size that I want the control to be, and when I set the AutoSize property to true, the control sizes correctly.
I have some custom properties that when changed will make the control have to grow or shrink to accommodate the updated contents but for some reason I just can't figure out how to make the control update it's size in response to these custom properties.
Could anyone point me in the right direction to sort this out?
Regards,
Heffo

One idea that comes to mind is to create a custom event. This is not a trivial task but you could define your own EventArgs which could hold the hold the new Size value. You could then fire the custom event everytime you update a GDI+ graphic.
Cheers!
Richard
may your code be error free

I do this in visual studio 2003, to get value from datagrid.
String myValue;
myValue = dataGrid1[dataGrid1.CurrentRowIndex,0].ToString();
does any one know to get value from datagrid using visual studio 2005
Thanks for help

Datagridview.CurrentCell returns active cell and DatagridView.CurrentRow returns the row containing the current cell. DatagridviewCell has property called value. I think it is easy to guess what it returns
