I'm going to bind data set to combo boxes. Data set is compound from 2 tables and joined by relation. The declaration is as follows:
Private tablePRAgent As PRAgentDataTable<br />
<br />
Private tablePRAgentLocation As PRAgentLocationDataTable<br />
<br />
Private relationPRAgentPRAgentLocation As DataRelation<br />
The table PRAgentDataTable has main rows with details in table PRAgentLocationDataTable. So first combo is bound to PRAgentDataTable and second - to PRAgentLocationDataTable, by relation. Filling adapters (and in consequence combos) while I add clause "WHERE col=@parameter" ends with "exception of type 'System.Data.ConstraintException'". When there is no WHERE clause everything goes right.
How could I overcome this problem?

Hey all
I'm developing an .NET application (C#) which hosts a WebBrowser control. The WebBrowser contains a Java Applet. I'm experiencing serious problems with ComboBoxes in this Java Applet. It seems like the comboboxes don't respond to mouseclicks. I can open the dropdown list, but I can't select any items. If I instead use the keyboard it works perfectly...But that's just not good enough
If I open the Java Applet in a "standalone" browser everything is peachy...
Has anyone experienced this ?? And maybe even got a solution ? :-P

Greetings,
I am having C# project that make the Executable also. The system use over 20 users' machines. Currently I installed the exe indidual machines coping the source and it is tedious task to do!

Any learning resources, plz send me!!! U r Welcome!
Thanks in advance!

Take a look at ClickOnce, you can install the application onto their machines using this but it'll automatically check for updates and download and install them if configured to do so.

Dear Code Project Users,...
I'm using VS 2005 C# .NET to create a windows forms application. The application uses two .NET components, Dundas Gauge and Cognitance VideoCog.
I've written the software on my development machine and it runs well in release or debug mode. I have the .NET 2.0 SDK installed. I've also tried the software on my laptop. This has .NET 2.0 installed too. All works well. However, typically, as these things always do... the one machine it doesn't work on is end users machine! This machine also has .NET 2.0 installed.
I have tracked the problem down to InitializeComponet, by placing a try catch around it. The error is as follows:
Exception in Form1 System.IO.FileNotFoundException. The specified module could not be found. (HRESULT: 0x8007007E)
at ... Form1.InitializeComponent
I've placed a MessageBox on the first line of InitializeComponent, however it never calls it. So it appears that its not my code causing a problem. So anybody any idea what file InitializeComponent is looking for, and more importantly how do I solve it?
Note, I don't have VS2005 installed on the end users machine for debugging, and putting it on there is my last resort!

Since you are using two third-party components, have you verified that those DLLs are also on the end user machine? You don't need to install them, but the DLLs should be part of your install process, even if it is to copy them to the application directory.

Hello,
I am facing the problem using dtpicker.
Im my vb.net application on selecting dtate from dtpicker i am displaying records from database in agrid
By default i am displaying the today's date in the format 08/09/2007.
When i execute my application and changes the date using keyboard for instacnce pressing 06 for date
and 08 for month it accepts date without moving cursor from the current position and i get result.
But if i press 6 (instead 06) it doesn't accept. I tried to trace tthis value in dtpickers keyup, keydown , text changed and keypress events but not getting the current value unless and until i move cursor from it.
I am terribly stuck to this problem.
Please help me. Anyone who knows how it read current text of dtpicker please let me know.
any help will be highly appreciated.
Thanks a lot in advance.

Hi,
My .NET com dll is working fine, if I install it on local machine, but if I install it on mapped network drive, I am getting Exception error:
"Request for Permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, Publickey Token=b77a5c561934e089' failed.

Any manage code running from a non-local driver, i.e.: network share, is not trusted and runs inside a heavily restricted sandbox. The code has no rights to any local machine resources, like the file system and registry, among many others. This is what's causing the exception.
You've got a bunch of reading to do to understand Code Access Securty[^].

Hi Everyone,
Consider the following scenario .... i am calling a function that can throw 2 custom exceptions for Ex:- ExceptionA and ExceptionB , that was derived from ApplicationException ie
try
{
MethodthatraisesException();
}
catch (ExceptionA e1)
{
LogMessage(e1);
}
catch (ExceptionBe1)
{
LogMessage(e1);
}
The logmessage will just log the details to a file.... In Such a case, can we rewrite the code above as
try
{
MethodthatraisesException();
}
catch (ExceptionA e)
{
LogMessage(e1);
}
Will there be any performance constraints in the second approach
|

First, please put large code snippets like this inside of <pre> tags to keep the formatting and help make it more readable.
try
{
MethodthatraisesException();
}
catch (ExceptionA e1)
{
LogMessage(e1);
}
catch (ExceptionB e1)
{
LogMessage(e1);
}
try
{
MethodthatraisesException();
}
catch (ExceptionA e1)
{
LogMessage(e1);
} There are some differences in runtime behavior between these. In the second example, you will only catch exceptions of type ExceptionA and anything derived from it. So, if ExceptionB is derived from ExceptionA this will work, if not you'll only catch one of the exceptions.
That being said, in your examples, you are "eating" the error. You catch the exception, log it, but don't pass it up the chain by calling throw(); to rethrow the exception. This may be what you want, but generally you should only catch an exception if you can do some meaningful cleanup work as a result; if not, let the exception bubble up to whoever is interested.
There really aren't any differences in performance between the two. The runtime still has to perform a stack walk all the way up the chain looking for something that will handle the exception.

If ExceptionB is derived from ExceptionA then both samples will work in the same way, because an ExceptionB will be cathced in the first sample by the first catch block, too. To catch them seperately, the catch blocks have to be switched.

Right, that's what I said:

Urs Enzler wrote: To catch them seperately, the catch blocks have to be switched.
Yes, given the first code sample and making the supposition that ExceptionB is derived from ExceptionA, the catch blocks would need to be in the opposite order. However, the original post stated that both exceptions were derived from ApplicationException, so the catch blocks would work correctly in either order. Again, the second example will only provide the same behavior if ExceptionB is derived from ExceptionA, which was one of the original questions.

I'd like to write a bit of C#/.Net that will generate text in a JPG format. I'm looking for any built-in-bits of .NET that will help me do this. Or, some sample code.
What I'm doing: I want to generate "album cover" JPG's to use on my iPod - but I don't want actual cover art. I just want a square, solid color background with the name of the Artist and the Album title printed on it, in colored text.
Since I have over 1000 albums, I'd like to generate this JPG algorithmically.
I would settle for a fixed font size, with truncation of long Artist or Album Name, but it would be nice if the text scaled to fit into the rectangle.
Thanks in Advance,
JoeRip

Take a look at the static method Graphics.FromImage(). Graphics.MeasureString() and
Graphics.DrawString() will handle the sizing and text overlay. There are a lot of properties that can handle smoothing and anti-aliasing of the text.
Sorry, I don't know of any existing source.
