Hello All,
I have set of BMP images in my D:\images folder. I need to display all the images one after the other in the dialog when the user clicks the play button.
Please let me know what kind of Activex control should be used , and how to proceed with work.
Thanking you …
Pruthvi G.

Use FindFirstFile once and FindNextFile to get file name each time in play button click and load that file using LoadImage and display it OnPaint.

If you are using MFC, check out CStatic::SetBitmap() .

You dont need to use of activex for bmp or jpg file if they are bmp files LoadImage is sufficient but if you have other formats CImage class is good for you,do you want to show them on dialog or a control?

please help me.
Thanks In Advance,

also have a look on DBFETCH sample (MFC Sample ).
It demonstrates connect to any database.

Sure! Very comfortably possible.

Hi, sorry i dont know this is correct forum for my question .
I took shortcut of MSDEV.EXE from 2003 server machine. My PC is windows XP. when i create MFC and when i run it , it shows cannot open afxres.h file.
and also ntdll.dll is not found.
When i create console application, it shows that build option is disabled.
Even i can rebuild the project, but it does not create exe file.
WHats the problem?
I dont want to install VC++ in my system, i have idea to get shortcut from another machine. Thats why i chose this way. But it shows lot of errors. Pls help me??

When i paste this DLL to system32, it tells that the dll is already used by windows ,Do you want to replace it?
When i click Yes. It asked me to save in another name. I cannot paste that.

What platform u r working ...i think VC 2003 ...k no probs ..i ll help u
then try another way to install it ..
1st way:
paste that dll in system folder not system32 ann then u build it.
2nd way:
1. open VC++ 2003 programe files folder wer to install it ..
2. And then open Search box folder type that box *.dll
3. And then its shows some vc++ dlls, right clic that dlls click open containing folder
4. then u ll paste that ntdll.dll to this folder.
5. Copy that file path and saved into Visual Studio (tools----on the way)
i thnk it lll work

See here[^] of course its not directly your answer but see this link because you must not copy system files.

Have you considered NetMessageBufferSend() ? At a minimum, you can always use NET SEND * for this.

Hello!
Here is what I am trying to do. I am writing an audio processing program that can read 16 and 24 bit WAV files into int (32-bit) buffers.
The 16-bit condition is straight-forward: I would read in the required number of bits into short buffers. However, since C++ does not have a native 24-bit datatype, and I would like to use the same buffer for 16 or 24 bit data, I would have to read the WAV file data into int buffers.
The further processing that the program does is on the ENTIRE contents of the int buffer and NOT on a byte-by-byte basis.
I have written the WAV read/write part of the program. Where I am running into a bit of difficulty is unpacking three bytes of data (24-bits) into a 32-bit container.
Should I copy the contents of the audio file into a temporary buffer as contiguous data and then fill my main buffer with three bytes of this data, and then skip a byte?
Is there any other way that you would recommend reading 24-bit data into a 32-bit buffer?
Thank you for your pointers, as it were. I do not expect code to be written for me, but pseudocode would be immensely helpful.
Thanks!

G'day,
You know sometimes pseudo code just seems too hard, hope code's okay
Something else you could consider is logical-ORing each byte as it's read into a variable of suitable length. You then bit-shift left by 8 bits and then OR in the next byte, and so on and so forth.
I can't remember the format of WAV files off-hand, I forget if they're little-endian or big-endian, but heres just one of many ways you could implement it.
Consider the code that follows. When executed, it produces the output:
Putting buffer into array of 24 bit nums
0x00010203
0x00040506
Putting buffer into array of 16 bit nums
0x00000102
0x00000304
0x00000506
Putting buffer into array of 24 bit nums - ROUND 2
0x03020100
0x06050400
Putting buffer into array of 16 bit nums - ROUND 2
0x02010000
0x04030000
0x06050000
** PORTABILITY WARNING **
I have not actually checked at runtime the sizeof different datatypes. (const int bitsInLong = 32) As well as the use of longs to store the elements of your converted and stored buffer. Long's are 64 bit in some systems.
This really must be done to avoid the code becoming broken. (it's late & I'm tired )
#include < stdio.h >
int main()
{
char soundBuffer[] = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06};
long buf24[2];
long buf16[3];
const int bufLen = 6;
const int bytesIn24Bits = 3;
const int bytesIn16Bits = 2;
const int bitsInByte = 8;
const int bitsInLong = 32;
long iam16Bits, iam24Bits;
long i, j, k;
char *ptr;
printf("Putting buffer into array of 24 bit nums\n");
ptr = soundBuffer;
k = 0;
for (i=0; i < bufLen/bytesIn24Bits; i++)
{
iam24Bits = 0;
for (j=0; j < bytesIn24Bits; j++)
{
iam24Bits <<= bitsInByte;
iam24Bits |= *ptr++;
}
buf24[k++] = iam24Bits;
printf("0x%08x\n", iam24Bits);
}
printf("Putting buffer into array of 16 bit nums\n");
ptr = soundBuffer;
k = 0;
for (i=0; i < bufLen/bytesIn16Bits; i++)
{
iam16Bits = 0;
for (j=0; j < bytesIn16Bits; j++)
{
iam16Bits <<= bitsInByte;
iam16Bits |= *ptr++;
}
buf16[k++] = iam16Bits;
printf("0x%08x\n", iam16Bits);
}
printf("\n\n");
printf("Putting buffer into array of 24 bit nums - ROUND 2\n");
ptr = soundBuffer;
k = 0;
for (i=0; i < bufLen/bytesIn24Bits; i++)
{
iam24Bits = 0;
for (j=0; j < bytesIn24Bits; j++)
{
iam24Bits >>= bitsInByte;
iam24Bits |= *ptr++<<(bitsInLong-bitsInByte);
}
buf24[k++] = iam24Bits;
printf("0x%08x\n", iam24Bits);
}
printf("Putting buffer into array of 16 bit nums - ROUND 2\n");
ptr = soundBuffer;
k = 0;
for (i=0; i < bufLen/bytesIn16Bits; i++)
{
iam16Bits = 0;
for (j=0; j < bytesIn16Bits; j++)
{
iam16Bits >>= bitsInByte;
iam16Bits |= *ptr++<<(bitsInLong-bitsInByte);
}
buf16[k++] = iam16Bits;
printf("0x%08x\n", iam16Bits);
}
return 0;
}

Thank you very much for your clear explanation and the code! It has been of great help and I modified it to exactly what I wanted.
Muchas Gracias!

Does anyone know of a way to have a program (MFC) open Microsoft Word with the Pen selected instead of the cursor?
I am working on a program with a tablet PC, and want to find a way to have Windows select the pen when it opens rather than the cursor.
Any help or suggestions would be greatly appreciated.
Thanks for anything.
