[.net] Windows Form Designer
Author
I'm currently wrestling with the windows for designer in attempts to create a gui. I have a UserControl class and Im adding controls to this. Lets say I add a check box, i name it, change the text, save, add a new check box, name it save, etc. I go through, for specificity's sake, 3 check boxes, 2 labels, a numericUpDown, a text box and a button.
Looks fine, I save and build. Alas, the designer has created upwards of 4 controls for each control i have created. I have checkBoxFoo, the first one i created. When i view the code, i have been given 4 of these, all named the same.
Aparently the windows forms designer has a bug, or a multitude of bugs. Swell. I delete these extra controls, fix the code that broke, go back to the designer, and there it is. "Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))" //one of two errors i tend to get//
I can no longer use the designer. Sure the code now compiles and the form works great, save for the delegates i was never able to add, the controls work fine.
I have this problem trillions of times a day. My question(yes there is one ;P ) is how do i get around this? I have come to grips with the fact that windows forms designer is going to put it in my rectum daily. Great, i just bring a tube of KY to work with me. Has anone been able to work around this, though? Maybe some manner of working, or cluster of properties i could set to stop the designer from violating me?
Cheers.
I've never had too many issues with the forms designer. Are you using C# or C++/CLI? What's the generated designer code look like (paste it here)?

C++/CLI the code i have right now is:
The designer has failed to properly create an of my controls in the initialize Component accept for the first two checkboxes, but my designer right now shows them as there. No error yet because i have yet to delete the duplicates. Partly out of shear terror, partly because it hasnt even created them properly yet.

I've heard lots of horror stories about the designer-generated code for C++/CLI. Unfortunately I don't have any experience actually using the designer in C++/CLI; I stay in C# where the designer has far fewer errors which are far easier to fix. So I can't provide much in the way of insight as to why the designer broke things and how you might avoid it in the future, alas.

Ya, ive tried creating controls one at a time and saving then going back and forth from code to designer, but two checkboxes in the has already duplicated the first. There appears to be nothing i can do, but grit my teeth and take it.
If it duplicated and actually set the controls inside the InitializeComponent, it wouldnt be so bad, i could just remoe duplicates when im doen creating new controls and then deal with it, but i have to copy positions from the designer with all the other properties that are "default" and hand create the controls...
i here there is some known issues on the msdn forums, but it doesnt provide workarounds just...ya we know theres and issue, sorry...
*shrug*
im about to pull a doctor scratch and sniff and yank my hair out.

Hey, sorry to bump this thread up again, but I had the same problem with my project. I deleted the project's intellisense database and it worked again, don't know for how long though, so give it a try.
good luck :)

thanks. the designer apparently has no issues on other computers that im aware of and the same on a few others. It may be that something became corrupt so ill try destroying the intermediate files and going from there. Cheers.
You might want to also try running "<Visual Studio Install Directory>\Common7\IDE\devenv.exe /resetuserdata" from the command line. It will clear out any config settings that VS has stored. Sometimes they can get corrupted and really bork stuff. It's less effort than reinstalling VS.
