Yes, it can be a const char* if you don't want to modify it. So, the line:
would be:
And also change the return value of ReadFile(). I wrote it as unsigned char* again because it was how i did it in the first example. But if you want to use char* instead of unsigned... -
Well, it does indeed have errors. Check out this one.
...Code:unsigned char* ReadFile(const char* szFileName, long& length); int main(int argc, char* argv[]) { long len = 0; const char* filename = "c:\\test.txt"; unsigned char* buffer = ReadFile(filename, len); if(buffer) { // Do something with the buffer //..... // And clean up afterLeave a comment:

Get proper HTML response
I am writing a small C# application that is supposed to download the files from a given URL. When i parse the HTML, i check the headers to see if the response is "text/html" and if so, to skip the file, since i suppose it's not a file (well, it is, but i just don't need text files or htm/html etc).
However, recently i was trying to download pdf files from: http://pdonline.brisbane.qld.gov.au/...icationmaster/... -
You'll need to kill excel, as it's not quitting, even if you call Quit().
Well, that will effectively kill all Excel processes, so if you have opened 10 excel instances...Code:private void KillExcel() { Process[] excelProcesses = System.Diagnostics.Process.GetProcessesByName("Excel"); foreach(Process p in excelProcesses) { p.Kill(); } }Leave a comment:

Ok, i see some things have been confused here and it has to do with the way the variables are declared... The example of vinayvaka will work as will many of the above examples (even though they didn't work for BahatiSiD). So, why?
Or... although the example of vinayvaka works as it is, if BahatiSiD tries it with his variables, it won't, i guarantee you that.
Well, BahatiSiD have declared his variables on the heap, hence they're not...Leave a comment:

You will have to add it in your .csproj file, like this:
<ItemGroup>
<Folder Include="MyNewF older\" />
</ItemGroup>
I agree with insertAlias on this as i can not see any point at all of what you want to do (unless you're building another VisualStudio, or some batch solution maker).
But anyway, that's the way to add the folder in the solution.

To add an event handler, you can write this in C#:
form2.FormClosi ng += new FormClosingEven tHandler(form2_ FormClosing);
Note that after writing +=, the intellisense (if you use VS) will tell you that you may press TAB to add the event (which will generate the rest of the line, and then if you accept the default name of your callback function you may just press TAB one more time and you have your callback function.

You could search for it like this:
managed c++ pass by reference
It's really managed by the CLR, but it's usually called just Managed C++ instead of C++/CLR and if you search for anything about it, use the term "managed C++".
As for your problem with passing by reference, i saw the thread and i believe you have solved it by now, but here is a simple pass-by-reference example:
C#:

Hello BahatiSiD and welcome to the programming world :)
MFC (Microsoft Foundation Classes) is windows library that wraps some portions of the Windows API in C++ classes. You have many graphical components in MFC that you ay use if you choose "MFC Application" (or anything starting with MFC for that matter) as a template. It was introduced in 1992 with Microsoft C/C++ 7.0 compiler, so it's older that Windows Forms, but is still in...Leave a comment:

You may inherit a control from the one you're using and make it have custom properties for the text color. In your derived control, set:
this.DrawMode = DrawMode.OwnerD rawFixed;
Then, when adding items, you may use properties or a function for that, but you'll have to keep some internal table (or even better make a custom class for the items that you're adding) that will keep track of the color of the words.
Then, override OnDrawItem...Leave a comment:

Thanks for the pointer Plater. That is some progress in the right direction. Although i still can't seem to put all the pieces together, it was helpfull. I just wonder if i am going to solve this the way i am doing it (making assembly with Emit) and if it's even possible. There is a switch in csc.exe (/win32icon:<file >) which can be used to assign an icon, but then the whole point of using Emit is to make the assembly dynamically, not to redistribute...Leave a comment:

Thanks for the reply joedeene. Well, i did search on google for hours before i posted it here with no luck. The problem is that i need this done with System.Reflecti on.Emit, so it should be dynamic assembly generation on-the-fly with AssemblyBuilder . I know very well how to embed resources in the current assembly (or in it's res/resource file). The trouble comes when i want to make some of those embedded icons to be the actual exe icon once it's...Leave a comment:

.NET dynamic assembly with a custom icon?
I've been recently working on application that generates .net assemblies on-the-fly using the methods in System.Reflecti on.Emit. It works well, but i would like to also change the icon of my freshly baked exe, so it would not appear the default icon.
The idea is to be able to embed the icon in the assembly, (i guess as a resource) and make that icon a default assembly icon. I am not talking about window icon that can be set on any window,...
