How to maimize the childframe??

I created a MDI project. I want that the child frame always full fill the client of the mainframe.
I used the style WS_MAXIMIZE in childframe's precreatewindow method.But I found that although the child frame maximized,but there was a sizing. It seemed that the child frame first showed in normal size and then changed into fullsize. Not nice.

How can I show the child frame maximized at the first time?

Thank you all.

I have solved the problem.
void CChildFrame::ActivateFrame(int nCmdShow)
{
// TODO: Add your specialized code here and/or call the base class

nCmdShow = SW_SHOWMAXIMIZED;
CMDIChildWnd::ActivateFrame(nCmdShow);
}
that's ok.

Hi...everyboby.
The time before, I posted a message about where webpages have theory about DSP (Digital Signal processing). However, I haven't known any webpages having these theory.
I spend much time searching on the internet, but I haven't had a exact result.
I wish that someone would tell me where I could receive the infomation about DSP in detail.Thank you so much....vtalau

Properly using TCHAR

I have this class

class A (definition)
{
...
private:
TCHAR _sWord[16];
public:
void Word( TCHAR word[16] );
TCHAR* Word( void );
}

class A (implementation)
{
void CWordData::Word( TCHAR word[16] )
{
this->_sWord = word;
}

TCHAR* CWordData::Word( void )
{
return _sWord;
}
}

The problem I want _sWord defined to [16]. But I cant figure out how ref it inside the methods.

Please help me with this ignorant ?

use this

_tcscpy(this->_sWord , word);

you cannot copy two string using = operator.

Trouble loading bitmap files

Kieroshark24-Apr-05 13:48

24-Apr-05 13:48

Hey, so I have been trying to load several bitmaps into a program I am writing.

I am using DirectDraw to display the graphics of this program. I want to load a bitmap from a .bmp file, then use the IDirectDrawSurface3::Blt method to display it.

First, according to a tutorial I am doing, I tried to write my own function to load a bitmap.

typedef struct BmpFile <br />
{<br />
	BITMAPFILEHEADER fileHeader;<br />
	BITMAPINFOHEADER infoHeader;<br />
	PALETTEENTRY pallete[256];<br />
	UCHAR *buffer;<br />
} BmpFile, *BmpFilePtr;<br />
<br />
<br />
int GraphicsEngine::LoadBitmapFile(BmpFilePtr bmp, char *fileName)<br />
{<br />
	HANDLE fileHandle = NULL;<br />
<br />
	if ((fileHandle = CreateFile(fileName, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL)) == INVALID_HANDLE_VALUE)<br />
		return 401; // Error code: Could not open file.<br />
<br />
	// Load the bitmap file header.<br />
	if (!(ReadFile(fileHandle, &bmp->fileHeader, sizeof(BITMAPFILEHEADER), NULL, NULL)))<br />
	{<br />
		CloseHandle(fileHandle);<br />
		return GetLastError();<br />
	}<br />
<br />
/* Rest of function commented out - the program never gets to it. */

Whenever I run this, CreateFile appears to successfully load the file, and fileHandle is set to a value. Then the function ReadFile fails. GetLastError returns 998 (which is the code for: Invalid access to memory location. ERROR_NOACCESS). Sigh | :sigh:

I was pretty stumped by this, so I looked around a while, and I found a function called LoadImage().

I looked it up, and came up with the code
HBITMAP hbmp = (HBITMAP)LoadImage(NULL, fileName, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);

But I have a problem with this, too Dead | X|

; I have no idea how to get the BMP data out of the handle... I'm not using MFC, so I can't use CBitmap. Is there any other way of getting the data, so that I can put it on an IDirectDrawSurface and display it using Blt?

If anyone can help me solve either method of loading a bitmap, or if that's not feasible, instruct me in the use of a third method, I would be greatly appreciative.

Thanks for your help, everyone. Smile | :)

Why you want to use adirectx versionthats at least 5 years old I have no idea. but...

this is an example
http://www.codeproject.com/directx/basicdd.asp[^]

By the way you can use the MFC libraries in a win32 app. Its much easier to show a bitmap and init'ing directx.

Cool, thanks a lot. Cool | :cool:

(And regarding why I am using an old version of direct X and why I am not using MFC:

After I learned C++, I was getting pretty bored of console apps, and wanted to learn how to windows apps. I tried from various tutorials for a while, but as I am fairly new to this, I was unable to make any progress.

Then I found an old book, called "Tricks of the Windows Game Programming Gurus", by Andre LaMothe. Its outdated, sure, but the gradient was perfect for me, and it was all I had at hand.)

If I use the default "Save", "Open", or "Save As" in the Menu of an Single Document Interface, my program is unable to open files internally. The files I open internally and those I use the above menu items on are not the same, and are not related.
PLEASE HELP! How to overcome this problem??

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
