See CImage::Load or LoadImage
CImage::Load(...) then use CImage::BitBlt(...) and in the end use CImage::Detach()

There are several ways to do what you want:-
1)picture control.
2)draw in the Dialog's paint handler
To get to the bitmap in the resource file, you can use LoadImage
Ofcourse you could draw on a owner draw button also.

Hi,
Im reading data from file like this..
char tTagName[16] = {0}
memset(tTagName,0,16);
PFile.Read(tTagName,16);//tTagName is PRO01_BLC101
PFile.Read(tDesc,24);//tDesc is Liquid Level
and the file looks like this...
//
PRO01_BLC101 Liquid Level % 2 //
So it read the file fine and got correct output.
But if the TagName is about 8 or 6 character it read the file wrongly..The file shows like this..
//
DFC101 DEPROP FEED M3/HR 1 //
I think it continously read 16 characters,so the tagname shows like "DFC101 DEPROP F " and tDesc is only "EED"..
How can i avoid this..B'coz i have to work with different tagname length..It may be 4 or 8 or 16 or 20..
What can i do for this?

It behaves correctly but your approach is wrong.. if you want to read different tag lenghts you can do it in two ways...
1) read byte by byte untill you fully read the tag name....
2)just read first 16 bytes as you did and find out the excat length of tagname from the "tTagName" and then move the file pointer to the length+1 position (in your case DFC101 has length 6, so move the file pointer to position 7 from the begining of file)
Hope this'll help

How can i do like this? I dont know pls give me any sample..?
For also copy char by char..

Hope you are using CFile.. if so use Seek method like,
After find the length of tagname anf before reading the next time write this code,
pFile.Seek(length+1, CFile::begin);
char by char reading, is reading a single char use 1 as count in Read method
pFile.Read(buff, 1);

Of course it is: you asked to read 16 characters, so it is logical that the function will read 16 characters.
I suggest that you store the complete line in a big buffer and 'parse' it after that. Copy char by char in the tTagName until you reach a blank space. Then start copying in the tDesc string. That's quite easy to do.

In addition to the answer from Cedric Moonen, it seems as if you can ignore lines starting with "//" since they doesn't contain useful information.
|
|
|
|
|
Take a look at scanf.

What are you trying to accomplish here?  One or the other is sufficient, but not both.
Use this as a starting point:
void main( void )
{
ifstream ifs("c:\\a.txt");
string sLine,
sTagName,
sDesc;
while (getline(ifs, sLine))
{
istringstream iss(sLine);
iss >> sTagName >> sDesc;
cout << sTagName << "|" << sDesc << "|" << endl;
}
}

Hi
How to include files in a directory with VC 8.0? with vc 6.0 we can do it
by Selecting in tools->options->Directories,where is the option for it in vc8.0 ?
Thanx
It takes only a minute to get a crush on someone, an hour to like someone and a day to love someone - but it takes a lifetime to forget someone.

The included directories for all of your projects can be affected in Tools --> Options --> Project and Solutions --> VC++ Directories --> Show directories for: Include files panel.
Alternatively you can set the include directories for your particular project in Project Properties --> C/C++ --> General --> Additional Include Directories field. I think this is recommended way.
I hope this helps.

I would say you should use the /I compiler option in your project/solution instead of visual studio's path settings. That is the recommended way and makes sure your project/solution will compile on any machine.

Why is the .NET graphics in windows forms app is so slow, manualy ploting some N points line segments using double buffer takes considerable time compared to say builder compiled app?
Is there special tips to make it faster.

I have char buf[10];
First i declared it as char buf[10] = {0};
In the middle of my code after using that buf, I again want to make buffer to zero.
How to do that?

Use ZeroMemory(..) as
ZeroMemory(buf, sizeof(buf));

For platform independent code:
memset(buf, 0, 10);

better use sizeof(buf) instead of 10, it will save you some headache if someone changes the "char buf[10]" in future.
|
|
|
|
|
I was using it to illustrate the call. sizeof will work on items declared on the stack, but not the heap. So, code like char* pChar = new char[30]; cout << sizeof(pChar) << endl; will output 4 instead of 30.

See the sample code
Example:
class MyClass
{
MyClass(int);
};
int main()
{
MyClass* p = new MyClass(10);
MyClass* p1 = new MyClass[6];
return 0;
}
how can I dynamically allocate array of objects using this class? do I need to overload operator new?
if yes how?

You have to supply a default constructor. From MSDN:
"No explicit per-element initialization can be done when allocating arrays using the new operator; only the default constructor, if present, is called. See Default Arguments for more information" (MSDN[^])

so we should have some "Set" function to do the task of parameterized constructor right?

Right. If you wan't to be politically OOP correct you write accessor functions to your member variables. In this case, with the member being an int, I would just assign directly to it in a loop.

it would be helpful if you say how such a operation is restricted with arrays. but it can be used with single object. is it the difficulty for compiler in writing same code for more than one object? or any oothr purposeful use for that?
