Have you tried writing down a step-by-step method of how you would perform this by hand? Sometimes that really gives you insight into how to have the computer do it.

What application is giving the error message? Is the error coming from Windows File Explorer? Or from Visual Studio? Where?

And WHEN does the error happen?

You must provide many more details before anyone can help you solve this.

You don't need a for loop to remove all the features. You could simply type "format C:".

I suggest you look into what methods are available for selecting complete ranges, and then copying them to other places. Doing it cell by cell must be what's making it slow.

It looks like your program is correct except for limiting the calculation to 100 or less. What did the teacher say is wrong with it?

What is the exact error message that you receive?

Are the namespaces in the DLL marked "public"?

Richard Andrew x64 27-Sep-20 11:26am View

Do you have access to the DLL source code?

Richard Andrew x64 27-Sep-20 11:21am View

What language is the DLL written in?

I'm sorry. I failed to notice that you properly decorated the delegate with the CallingConvention.Cdecl attribute. I was supposing that the callback might have required the stdcall convention. Like you, it's been a while since I've done native/managed interop.

What does the code that calls the callback look like?

Richard Andrew x64 2-Jun-18 16:28pm View

If it crashes after leaving the callback, that is a very strong indicator that the stack is corrupted on the native side. I would recommend making sure that CDECL is the right calling convention for calling into managed code.

I'm confused by your terminology. You say "it fires and runs", then you say "it blows up", "delegate finishes".

Perhaps if you could be specific. Where exactly is the thread when it "blows up?" Is it before, during or after the callback function is executed?

Do you get an error message about the stack being unbalanced?

Have you stepped through the code with the debugger?

Have you tried Google?

This is ALMOST a good question because it contains the problem and what has been tried. But it's missing the crucial ingredient of exactly what the question is. What is it supposed to do, and what is it doing wrong?

Richard Andrew x64 2-May-15 19:26pm View

Could you clarify what exactly you are asking?

MSDN says that you'll get that exception in the following circumstances:

The form being shown is already visible.

-or-

The form specified in the owner parameter is the same as the form being shown.

-or-

The form being shown is disabled.

-or-

The form being shown is not a top-level window.

-or-

The form being shown as a dialog box is already a modal form.

-or-

The current process is not running in user interactive mode

Reason for my vote of 4
Very succinct and to the "point!"

Thank you.

You've probably not gotten any responses because your explanation is too complicated to follow. Please restate what you're looking for in a more straightforward manner, and you might get some responses.

But what prevents the unauthorized user from calling the web service? I'm sorry if I'm missing something obvious. Thanks for your help.

Richard Andrew x64 20-Jul-11 18:40pm View

How does this prevent a unauthorized user from retrieving the password?

Richard Andrew x64 20-Jul-11 18:39pm View

I'm talking about the password for the database itself. It has to be stored on the client machine. But what is the preferred method?

Richard Andrew x64 4-Jul-10 22:30pm View

You demand "where is my mistake," and don't provide any code to look at. Dumb question.
