Hi, I have some data in char *szBuffer. I need to read the data fom the buffer nad put them into respected variable.
Suppose szBuffer returns "15,30\r\n CMD OK \r\n" , then I need to keep 15 in one variable,30 in other and CMD OK in other variable.
Can anyone help me how to do this. Any sample code will be good help for me.
Thanks..

Read up on tokenizing. See strtok() and strchr() for starters.

The standard library is your friend if you're using C++. Have a look at:
- istringstream
- getline
and see what you can cobble together.

We don't do homework around here. You have been given enough hints of what to use and read up on. Try to get something wotking. If you then have problems, post your code and explain what does not work. Someone will try to help you out.

Hi
I want to get the column names in CListCtrl. Can any one show me the code for it.

Did you try the GetColumn() method?

I have made my own XML format which looks a bit like HTML, but I need a browser to read it. The built in browser windows in Visual studio can't read it, so I need to make a simple XML reader that displays the XML like HTML. Is there any very simple open source project I could edit, or is there a simple way to make an XML reader from scratch? Help would be appreciated

You can use the Microsoft MSXML[^] tools, or try a Google search for open source alternatives.
It's time for a new signature.
|
|
|
|
|

if it follows XML standards, then most (all?) broswer will be able to read it; it might not be able to understand the tags and their meanings (how to display them), see : http://msdn.microsoft.com/en-us/library/ms754529(VS.85).aspx[^]
You will need to create some sort of stylesheet to help display your XML files.
Watched code never compiles.

I will give you a simple example of what I'm trying to do:
Text in here will be displayed as normal, but <my own="" tag="">text in here will have a new formatting
Is there a way to make a "browser" that reads this kind of markup instead of HTML?

I have two option button or radio button BS_AUTORADIOBUTTON on a dialog. I have one label which I show just after first radio button. Some of label's portion is overlapping with radio button. So whenever I click on radio button, radio button comes above to that label. But I want label should always remain at top. How can I achieve this?
Thanks,

The z order of controls on a dialg is controlled by their order in the dialog box.
How to set this changes depending on which version of Visual Studio you are using.

Don't hack...Fix the overlapping in the resource editor.

Does the label belong to the radio button or is it an unrelated control?

While running a program I got the following error Message:
Program:e:\Work\Cricket\Debug\SlogOut3D.exe
File:f:\dd\vctools\crt_bld\self_x86\crt\src\dbgdel.cpp
Line:52
Expression:_BLOCK_TYPE_IS_VALID(pBlock->nBlockUse)
How to get out this error?

If you ever needed an advert to avoid pointers and dynamic memory allocation until you know what you're doing, this is it! The error happens when you're trying to delete an object or free a block of memory with a pointer that's invalid.
You're either:
- trying to delete or free something twice
- overwriting the pointer with an invalid value
The way of getting around this sort of error is not to do it. Use smart pointers rather than raw pointers to hold objects and use stack based variables wherever you can.
Cheers,
Ash

Could you explain me how to delete a pointer using a Smart Pointer?
|
|
|
|
|
That's the whole point: you don't. A smart pointer manages that task on its own and you don't have to care about it.
|
|
|
|
|
You don't delete anything, that's the beauty. Whenever you do a new you immediately assign the result to a pointer class and even if your code throws an exception the object's destructor is called automagically. This will stop double deletion but won't stop wild pointer writes.
Cheers,
Ash

I have faith that Aescleal has given you the correct answer for your question.
But here's another couple of thoughts...
1/
Pretty much whenever I delete a pointer, I set it to NULL afterwards. This way I find bugs sooner, and simpler.
So...
ASSERT(pSomething);
if (pSomething)
{
delete pSomeThing;
pSomething = NULL;
}
This will let you catch double deletes.
2/
You could have found the bug yourself. When you got the assert, choose to debug your program. The error shows up in code you did not write. But look at the call stack window. (Debug, Windows, Call Stack on VS2008). Then look up the stack until you get to code *you* wrote. There you will see the mistake.
99% of the time, the bug will be in your code, even if it shows up elsewhere.
Good luck,
Iain.

Iain's point about the debugger reminds me of another point: Always fix bugs as soon as they happen, don't keep piling other stuff on top of buggy code. It's easier to find problems in a 1000 line program than in a 10,000 line one so you'll be more effective if you don't wait until your code is a lot bigger.
Cheers,
Ash

How to extract BITMAPINFOHEADER structure from BITMAP structure . I have a bitmap file
Rajesh
|
|
|
|
|
Call LoadImage to load the bitmap from the file to get a HBITMAP.
Call GetDIBits on the handle to get a BITMAPINFO structure.
BITMAPINFOHEADER structure is contained with the BITMAPINFO structure.
