Ok, I give up. Was working great on my control, and now I can't get anything but this error message when I try to drag my control onto my test project.
> The user control 'Blah' could not be loaded. Ensure that the library containing the control has been built and a project reference has been made to the library containing the control. If you have changed the name of the user control, close and re-open the control's designer to update the toolbox item.
I'm sure it's something TOTALLY simple to fix this, but I'm going insane!! It used to work, and now, nothing!! I've been stuck for 2 days now.
// Add a testing project
1) Select File - New - Project
- Click 'Windows Application'
- Set Name to 'TestMain1'
- Click OK.
// Create a new control
2) In the 'Solution Explorer', right click "Solution 'TestMain1' (1 project).
- Select 'Add - New Project'
- Click 'Windows Control Library'
- Set Name to 'Test1'
- Click OK.
// Build...
3) Press F7 to build both projects.
// Now add the control to the main project.
4) In the 'Solution Explorer', double-click the file 'Form1.cs'
- View the 'Toolbox - Windows Forms'
- The bottom of the list should show 'UserControl1'
- Click on 'UserControl1' and drag to the form.
* Error Message Displays*
Can someone please tell me what I am doing wrong in the above situation?
I tried completely reinstalling .NET and I have also just updated with SP1.
Thanks in Advance!!

I think you need to add a reference to the control library from the windows forms application. In solution explorer, right click on "References.." in the windows app, select Add Reference. Change to the Projects tab, and tick the control library.

/nod, the process that I have listed will automatically add the reference.
Going ahead and doing it again had no effect.
Thanks for the attempt.

GRRRRRRr..... This little example I used works FINE at home.
Great, that means that something is now corrupt. Going to completely uninstall and reinstall the developer's system.
|
|
|
|
|
Ok, finally fixed.
Uninstalling/Reinstalling does nothing. The uninstall does not affect the registry.
Remove key HKEY_CURRENT_USER/Software/Visual Studio
|
|
|
|
|
Let me guess, The path that you built the control in, contains a # symbol.
I ran into that a few days ago. What a pisser...

I have a string ,if somethings happen in my applicaion it ends with "AND" statement,I check if it ends with "AND" withEndWith() ,if return true I want to remove "AND",I can't do it with Remove(),because I don't know the starting position.
How can I manage this operation?

To draw a transparent bitmap on the form I use the old trick from VC++ which is to draw a bitmap that is stored in ImageList. When you set TransparentColor property of ImageList to the color of the bitmap's transparency color, the bitamp is drawn transparently on the form.
My problem is that this doesn't work when there is another bitmap on the form behind my bitmap. I want to see this another bitmap through the transparent bitmap.
In VC++ a was using SRCCOPY, SRCAND and SRCINVERT in BitBlt(). I don't see any equivalent of raster operation codes in C#.
Any ideas?

Bitmap bmp = Bitmap.FromFile( strFilename );<br />
bmp.MakeTransparent( clrTransparentColorInBitmap );<br />
<br />
Graphics g = GetGraphicsObjectToPaintOn();<br />
<br />
g.DrawImage( bmp, x, y );
Took a bit of searching to find it

Thanks James
Yes, it's a nice alternative to was I was doing (using ImageList class). But I forgot to explain that I was using PictureBox control not device context. I still wonder if I could use two PictureBox controls, one transparent over the other.
Thanks again

ive got an inherited form base class (BannerDialog) that has a banner on top and buttons on the bottom. the banner and buttons are anchored to the form using the ide'd design window.
my problem is that on the inherited form (MyDialog : BannerDialog) the banner and buttons dont move when MyDialog resizes.

Did you call base.OnResize() ?
Jerzy
|
|
|
|
|
im not certain what you mean. i currently do not call base.OnResize().
If i do, do i override BaseClass.Resize()? and if so, how do i resize the base class's window size? where do i get the dimentions?
*** added ***
if i delete the inherited form's "this.ClientSize = new ..." in the Initialize component, and do nothing else, it seems to work. the form snaps to the inherited window's size and anchors properly. but i dont understand why.

|

well, after toiling around the msdn i found a little blurb stating that controls on inherited forms that have anchor properties MUST be set to PROTECTED and not PRIVATE..
exposing controls is the absolute wrong way to write inherited forms (im no architect, but im pretty sure that breaks the model). -- unless there's a way to block the user from directly accessing the PROTECTED control aside from setting it's anchor.
so the solution..? in base.Resize() i simply made the layout recalculations myself. years of vb experience pays off.

Hello, I've a datagrid with a dataset wich I get from a WebService. When I insert, update, etc there are some messages that I want customize (null value not allowed, duplicate key, etc). This messages are created "locally" before to send modifications to the database, but I don't know how to catch it before show it in order to customize.
Any idea or suggestion?
Thank you.
