for 1-bit-per-pixel data, there is only so much you can choose. IMO chances are great your intuitive choices are what PixelFormat.Format1bppIndexed also does. The biggest uncertainty would be the ordering of the 8 pixels that constitute a byte. there is 50% chance there.

Hello everyone,
I encountered the following problem :
I want to make a C like interpreter and I've found some good materials but only in C. So I have a (modest but) functional interpreter written in C and I would like to improve it in C#.
I don't know how to make a .dll from that C code and if I could maybe I could invoke it from C#, or I could rewrite the whole program in C# but in .NET I don't have
<#include setjmp.h> which is used in the C interpreter.
So if anyone knows how to make a .dll or something I could invoke from C# or if it is any alternative to
#include <setjmp.h> in .NET please let me know!
Thanks in advance,
Tamash

You can make a dll in C# by making a Class Library project.
To call the C code from C#, you will need to research P/Invoke. You will need to replicate all the function signatures, structures and constants in the C header file in C#

Hi,
if you really want to go the trouble, study P/Invoke. I have a little article[^] that might help.
However, I wouldn't do such things in C nowadays, C# is much easier. You do not really need setjmp, there are several ways to avoid it, e.g. restructuring your set of methods; what you also could do is use a specialized exception. Partial example:
try {
} catch(SetjmpLikeException exc) {
} catch(Exception exc) {
}
...
throw new SetjmpLikeException();
...
public class SetjmpLikeException : Exception {
}

I wrote a program for Windows XP that does not function in Windows 7. Is there a way I can build the program in Visual Studio so that it will require Windows XP to install?
|
|
|
|
|
The first thing to do would be understand why it doesn't work on Windows 7, you shouldn't be creating an app that is dependent on an older OS.
You can check for the OS version at startup but the logical thing would to would be prevent it from installing in the first place via the setup.

I agree. This is what my question pertains to.
|
|
|
|
|
Then it depends on what tool you are using to create the installation package. You can create a custom action to validate the OS level.

It is a Visual Studio project, and so far I have been using Video Studio to create the installers. Is this possible to do with Visual Studio?
|
|
|
|
|
Yes. There are plenty of examples for creating custom actions with Visual Studio

Fix the program; what problem does it have?
|
|
|
|
|
Come on, when a program depends on some third party components, that's pretty normal. And nothing you can change!
|
|
|
|
|
Then make a note in the documentation to that effect and let the buyer beware.

please,
what is the equivalent of FileSystem.GetFIleinfo() in C#
thanks

Take a look here[^] and you will see how MSDN shows the differences between the various .NET languages.
It's time for a new signature.

Um. Difficult...
FileInfo fi = new FileInfo(@"C:\myFileName");

Good morning.
I have created an Excel add-in to display a Import tab with several buttons designed to run VBA macros.
I only want this tab to display on the one workbook and not every instance of Excel. I am trying to test for the specific spreadsheet name, but the If statement keeps defaulting to the else condition. I have the following:
public RibbonCustom()
{
InitializeComponent();
this.tabImport.Visible = true;
if (Globals.ThisAddIn.Application.ThisWorkbook.FullName.ToString() == "ImportFile.xlsm") { this.tabImport.Visible = true; }
else { this.tabImport.Visible = false; }
}
The MessageBox.Show doesn't work.
Any suggestions? WHEELS

string theName = Globals.ThisAddIn.Application.ThisWorkbook.FullName.ToString();
if (theName == "ImportFile.xlsm")
{
this.tabImport.Visible = true;
}
else
{
this.tabImport.Visible = false;
}
Put a breakpoint on the declaration of theName, and run the code. Somehow, those two strings aren't the same.

Hi Eddy. I found one issue. I was using >FullName instead of .Name, but unfortunately it didn't fix the issue. Trying to figure out a way that I can see the contents of the code (variable).

That would be debugging[^]?

Won't debug unfortunately.

Tried to attach the debugger to Excel? If you can't debug, then you'd be limited to something like logging to a textfile.
