No, it takes jpegs and tiffs too but it uses the same strategy (fread) and processes the pre-DIB section information in itself. But I have a bmp to deal with. I've not read up on DIB, DDB etc, and am learning as I go along. So I guess (sorry if I'm being unbelievably dense), what I want is somehow to get the pImage out from the resource. Is there something like:
char* pImage = Somefunction(IDB_BMP1);
Any links would be great. Meanwhile I'm hurrying along with my background reading. I did find how to get (I hope it works) to get at the colortable:
HGlobal pBMP = ::LoadResource(NULL, ::FindResource(NULL, MAKEINTRESOURCE(ID), RT_BITMAP));
PBITMAPINFO pBMInfo = (PBITMAPINFO) (pBMP + sizeof(BITMAPFILEHEADER));
int bitCount = 8;
int clrUsed = 0;
if (pBMInfo->bmiHeader.biBitCount != bitCount ||
pBMInfo->bmiHeader.biClrUsed != clrUsed )
return;
memcpy(pPalette, pBMInfo->bmiColors, (4*clrUsed));
I havent tried it out yet. Surely this pBMP is not what I'm looking for? I need a char* back, and not sure what to do with an HGlobal.

The code you've posted isn't correct. The bitmaps stored as resource doesn't have BITMAPFILEHEADER structure; they start with BITMAPINFOHEADER.
You'll have to create a memory buffer and copy BITMAPFILEHEADER followed by stuff loaded with LoadResource call.

Okay. Thanks. A little digression. I removed the offset for the fileheader and tried to access the color table like this: but no luck!
char* pBMP = (char*) ::LoadResource(NULL, ::FindResource(NULL, MAKEINTRESOURCE(IDB_BITMAP1), RT_BITMAP));
PBITMAPINFO pBMInfo = (PBITMAPINFO) (pBMP );
int bitCount = 8;
int clrUsed = 0;
if (pBMInfo->bmiHeader.biBitCount != bitCount ||
pBMInfo->bmiHeader.biClrUsed != clrUsed )
return;
memcpy(pPalette, pBMInfo->bmiColors, (4*clrUsed));
What am I doing wrong? THanks for all this help!

clrUsed is zero. 4 * clrUsed is zero as well.

Yikes. I needed to bitshift it to 256. Many thanks. It looks good now. A big problem resolved!

How do you execute the MapNetwork drive wizard? (and disconnect drive)
Is there any other method than trying to simulate a context menu command on MyComputer?

I've got a CStatic with more text than gets into the window, and would like to make the text scroll programmatically. CEdits do have LineScroll which do precisely what I want, but alas this method is not available for static controls. Does anyone know some custom-made routine or anything to achieve this behavior? The thing can be replicated with CWnd::SCrollWindow and all that stuff, but details are clumsy and maybe someone has already done the work 
Thanx

Is read-only edit control an option?

It's almost an option, but notentirely: this way, the cursor appears, and I don't like any cursors around. Also, disabling the edit control gets me almost there, but the text is grayed and I want it black (do you know how to change this?).

You mean the insertion point cursor, right? So maybe handling WM_SETCURSOR will get rid of this problem?

I tried, and it doesn't seem to work (the docs says one should return TRUE from the parent to stop further processing to the childs). Anyway, I guess this has to do with the mouse rather than the text cursor.

So you handled WM_SETCURSOR in parent right? Maybe you should add handler in edit clas, do not call base class implementation and just set cursor to standard arrow instead?

Have just tried it, returning TRUE and FALSE --nothing. I guess this message has nothing to do with text cursors, but rather it is suposed to handle mouse icons and stuff.

Wait - what do you mean by 'text cursor'? A caret? This blinking | thing? In this case, you'd have to probably handle WM_SETFOCUS (or EN_SETFOCUS) and call HideCaret.

Yes, I refer to the | blinking thing. I've finally found a solution: it doesn't involve handling those messages, but rather cheating the system with the enabling/disabling thing by handling WM_ENABLE. I found this trick here[^].
Thank you very much for your efforts. Keep the good work helping people here at CP!

I'm not to sure there is a way to do this easily, Basically within my OnWizNext I validate data, if this fails, I want to drop out of the wizard process for the user to modify data. I was hoping to be able to call OnCancel() however this doesnt work, has anyone any ideas?
|
|
|
|
|
Popup a messagebox, tell some data error and return without call base class
overload function "OnWizNext"
I am seeking...
For what?
Why did you ask me for what? I don't know!

Hi all,
I am using msado15.dll in my application by #import directive
as follows
#import "msado15.dll"\
no_namespace rename("EOF", "EndOfFile")
while compiling i am getting the following warning
"\debug\msado15.tlh(405) : warning C4146: unary minus operator applied to unsigned type, result still unsigned"
can any one explain me why this warning hapens and what is the solution.
Thanks in advance

This is an MS bug, Q253317. It can safely be ignored, as I have been doing so for years. The quickest way to avoid seeing it is to change your import statement to the following:
#pragma warning( push )
#pragma warning( disable: 4146 )
#import "c:\program files\common files\system\ado\MSADO15.DLL" no_namespace rename( "EOF", "EndOfFile" )
#pragma warning(pop)
</code>
HTH-

I'm using _ftime64(__timeb64) to obtain the system time. but when compiling, I receive "unknown identifier"-errors.
include files (found on msdn):
#include "time.h"
#include "sys/types.h"
#include "sys/timeb.h"
code (found on msdn):
struct __timeb64 timebuffer;
char *timeline;
_ftime64( &timebuffer );
timeline = _ctime64( & ( timebuffer.time ) );
Have I forgotten an include file? 
Is there a better way? 
tnx

I'm not sure it's actually a better way, but you need VC.NET for ctime64. If you prefer to use VC6, then ctime (without 64) is your only choice.

I don't have .NET, so ctime it is. 
one more thing:
The msdn-doc says this about ftime: All versions of the C run-time libraries.
