In my MasterPage I have this code:
private string _callbackResult = null;
protected void Page_Load(object sender, EventArgs e)
{
string cbReference = Page.ClientScript.GetCallbackEventReference(this, "arg", "Result1", "context");
string cbScript = "function UseCallback1(arg, context)" + "{" + cbReference + ";" + "}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "UseCallback1", cbScript, true);
}
public void RaiseCallbackEvent(string eventArg)
{
string res = AgentLogin(eventArg).ToString();
_callbackResult = res;
}
public string GetCallbackResult()
{
return _callbackResult;
}
When I open the first page - everything is ok! But when I move to the second page I can see that there is no "UseCallback1" JavaScript function in HTML!
Help me please to fix this problem!

How could i set righttoleft for listbox when im using draw item event and the listbox Drawmode is set as OwnerDrawFixed.
i tried following code in drawitem event:
this.li_author_persian.RightToLeft=RightToLeft.Yes;
but it doesnt work.

OwnerDraw means your settings on the item do nothing, it's your own code that controls how it is drawn.

Thanks, so how can i set it right to left ?!!

If you're owner drawing, then you're drawing it yourself, aren't you ? Does DrawString have properties to support this ?

Dear Christian
Unfortunatly DrawString have not RightToLeft property?
|
|
|
|
|
I'm sorry, I've never drawn a righttoleft string, all I can tell you for sure is that if you've set the control to be owner drawn, no other property is going to matter, your own code is completely responsible for how it is rendered.

Hello

Using multithreading, but I think you already know that!!

So what is wrong with that?? Each form will make an independent connection to your database. Whether they are 3, or even 100 screens. Each will make its own conection without knowing about other connections or screens.

If you still need more help, yes! If you post more details perhaps.

Not possible. Every machine that runs your program will need to have the .NET framework installed.

hi all i have a pro on hand now..
i have 2 buttons in my application and i want to call up text into the richtextbook..i can do this however after pressing button 1 the text will be clear and display text will button 2.. i want both the text to remain ,how do i do it?
|
|
|
|
|
this.richTextBox.Text += newdata;
Just add your new string behind your old string in richTextBox.
|
|
|
|
|
 Performance issues!
this.richTextBox.Append(newData);
Remember that strings are immutuable and doing: string += newData will create a new object everytime.

 Bug issue!
At least with .NET 1.1 (didn't check 2.0), RichTextBox.Append() cuts off the text after ~32K, even though the MaxLength property has been set to a higher value! Almost got my head ripped off after we had been working with a program I wrote that suffered from this bug.
So if you have to concatenate a lot of strings, you should use a StringBuilder and then assign the whole string to RichTextBox.Text.

Never come across that issue before (havn't filled in that much text). I agree that the best way is to use a StringBuilder first if concatenating strings programatically.

Hi,
I have made a setup for a windows application. But the problem is that it starts to re-install ( or repair I dont know since a progress bar similar to that when removing an application runs fast) when i run it for the first time. I have also used some COM components in it too since there are some AxInterop & Interop files too. Do i need to register them too. If yes, then how?
Please tell me what can be the possible problems, flaws or other descrepencies?
Regards,
Wasif Ehsan.

I have some c++ source code, which I have updated to compile under VS2005. When I attempt to add the code as a reference in a C# project, it states that it is not a valid .NET assemply or COM component. Also, I have tried adding the DLL in a DLLImport statement:
[DllImport("@DebugPath DLLName")]
A first chance exception of type 'System.AccessViolationException' occurred in CSharp.dll
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
The DLL is in the project's bin/Debug folder.
I thought that compiling the c++ DLL in VS2005 would allow c# project to reference it. I saw another option of creating Managed c++ classes, but I didn't want to go there unless i really had to.
Am I doing something wrong?
Regards

C# can only reference a managed DLL. You cannot use unmanaged DLL directly to C#.
Export your function from C++, so that you can use it from C#.

Is Generics a .NET form of C++ Templates?
