Hi - a Win32 project is perhaps the most difficult type of project to get together. Basically, you want to create an MFC project, MFC is a library that sits on top of Win32 and makes things a lot easier.
However, C++ is more complex ( and also more powerful ) than C#. I'd recommend you first do some console programming to learn the language, then buy a good MFC book before continuing.

Im relatively new to programming and have never come across a memory leak problem before and cant seem to figure out how to fix the problem. For some reason I have this memory leak
memory check error at 0x000349C0 = 0xFF, should be 0xFD.
memory check error at 0x000349C1 = 0x00, should be 0xFD.
memory check error at 0x000349C2 = 0x03, should be 0xFD.
memory check error at 0x000349C3 = 0x00, should be 0xFD.
Detected memory leaks!

Looks to me like your program has not ended normally ( for example, you were debugging and just stopped without letting the program end ). The code in question is created by MFC, so unless you're underlying document object is leaking memory, I don't see how you can have done anything to cause it.

This means that you have corrupted your heap in some way. Is it possible that you have stepped outside the bounds of an array?

Hi,
I have many problems with pictures inserted in my documents after I compile them in Html Help Workshop. Sometimes the pictures are nt shown.
Anyone knows if this is a bug?
Thanks

Sounds more like the problem is with the path to the pictures. As you are aware HTML help is nothing more than a bunch of web pages compressed into one file. One easy way to make sure they all look the way the pages are suppose to is open them individually with internet explorer.

Set the image path relative to the base path and if it still happens, try to add the "BASE HREF" statement to set this base path.

I'm working on a MFC application. I want to have some kind of a key mapper. I want to be able to convert key codes to the keys name - if for example the user presses "backspace", "Backspace" is displayed in some edit field.
Is there any easier way to do this than to set up a gigant switch and/or STL map, or is there even a pre-defined map or something like that?
You don't want to do work more that you have to!

A switch is hideous. A map is made for this sort of thing. How huge can it be, anyhow ? I've built much bigger maps than this.

>>MaxHeap<array<int>> m; I'm using vc++. Why it is so
Because you need to pust a space between >>
Example:
MaxHeap<array<int> > m;
It'll work if you put the space in. The space is required, because the compiler see this >> as operator >> (instead of template brackets).

Hi,
I have a MDI project.
How can I exchange data from one Editcontrol to another editcontol. I open two instances of a view.
I change the text of the Editcontrol in one view.
Afterwards, I close the view. The changed text should appear to the second view in the Editcontrol.
Can you help me please?

Hi,
You may use the CDocument::UpdateAllView method.
This will call the OnUpdate method of all view instances which are currently displaying the same CDocument object.

I want to use VC++ *.lib into C# application. I know that I must compile the lib in to a dll. How can i do that? Any method and hits to me.
|
|
|
|
|
IMO, the easiest way is to create a DLL that exports functions that simply call the .LIB functions:
BOOL __stdcall fooFunc_DLL(int p)
{
return fooFunc_LIB(p);
}
that way, you don't have to change the .LIB functions, and the DLL is a simple one-step pass through.

I suggest you start reading here[^] in the MSDN about DLL's. In order to use your object library (the .lib file) as a DLL, you may need to create a DllMain function in a .C or .CPP source file, compile it, and link it to your .lib.
You will need to research further what it takes to use a DLL from C#; that's something I don't know about.
By the way: I don't know who the two boneheads were that rated your post a 1. I think your question is valid, asked politely, and in the correct forum. Good luck.

Hi
I am using SQL Server for my database programming using CRecordset. but now i have to use Oracle. I am connecting to Oracle using ODBC. How to access tables from Oracle. Tables having BLOB datatype fields. how to access Oracle through VC++. Can u plz guide me.
Thanks in advance.
|
|
|
|

Hello,
You can use CDatabase and CRecordset classes for accessing the database and retrieving the records from Oracle. While passing any query when you mention the table name is sufficient, as the ODBC will be connecting to the whole of the database and tables are part of the database.
If the reply helps you, Don't forget to rate it.
