Cannot convert control (works fine on localhost though)
Hi Experts,
I'm having a problem with difference between my online environment and my localhost.
I have compiled my application and uploaded it when it worked on my localhost..Everything works, except for one thing and I cannot figure out why it doesn't work. In my eventlog it tells me the following:
Event code: 3005
Event message: An unhandled exception has occurred.

In my ControlArticle.ascx.vb, I check in the Page_Load function, which control needs to be added to my page depending on a templateID.
Dim control As ControlShowFormulier = LoadControl("~/controls/fo
placeHolderModule.Controls
That's all I do and it works for every other control, but this one is feeling obnoxious for some reason. Anyone got any idea why this could happen and better yet...how I could fix it?
Thanks in advance,

GJ, Max,
I am pretty sure you are not the only one experiences this kind of problem. In any way that matter, if problem's caused by actual coding or not. It's nice to have some solutions to try (and ppl may add another explaination to it)
Aww, you can ask to get this question PAQ of course ^^.
Greeting,
JINNY ^^

I can wait for a while as well. :) Like you said it's nice to see different reasons why this would happen.
Just hope I won't forget about the question though.. ;)

I have found that these kind of compilation issues are not so much problems with coding, however more a problem in Visual Studio / ASP.NET. Check out Scott Gu's blog about it..he recently made a post about this and other compilation problems.

Jinn, thanks for your help, this question might be usefull for others as well, so I have PAQ'ed it now. :)

Ohh,
I have read the blog, it is really helpful. Since I don't have this kind of problem, but I found something interesting to play with. (I might even experience it later).
Sometime I got that (after complied successfully several time), what I did was closing all the opening file (even solution file). Then reopen it and complie again. It's sounds weird but helps.
Thank for the credit, too Master Max. ^^ (I think my solution wasn't really helpful,)

Well...I have it solved in a way that doesn't make a hint of sense to me at all. I've changed from a compiled version to just using the source as I have it on my local machine. That works flawlessly.
I have the <%@ Register... tag at the ascx file (remember it was in a control)
I've seen similar things before, and it proved to be a matter of changing a small thing, allowing the site to be recompiled and suddenly it would work, this however would be with a main control. Sometimes even commenting out a line would work..then calling it (it won't work as suspected) but it works...uncommenting that line...eh voila it works again as normal.
I still have no idea why these bugs are happening, but I'm pretty sure they have nothing to do with the actual coding.
Thanks!
Regards,
Max.
