Ahh, so you're using VS 6.0.
Unfortunately this version of Visual Studio does not have a direct Web Services support, like it doesn't have C# support at all. You need to do everything manually in this version. Manual labor is highly difficult and most prone to errors. In order to efficiently use Web Services, I recommend you to move into Visual Studio 2003 .Net version.
If you must use VS 6, then start by learning SOAP, as it's the "language" of Web Services. Then create an Internet-connection, open a HTTP connection to the Web Service, generate a string that can be interpreted as a SOAP request with the proper parameters, post a HTTP Post command into the service and fetch results with HTTP Get. I'm sorry I can't give any more detailed instructions or specific help, because I've never done this manually. The auto-generated wrapper classes (Add Web Reference) have saved me the task.

Hi
I have a CString type variable that Content is Numberic
how can get this CString as a Integer?
|
|
|
|
|
Hope this will help You.
Example
CString str = "45" ;<br />
int m ;<br />
m = atoi(str.GetBuffer(str.GetLength() ) );
|
|
|
|
|
That is wrong. DO NOT call GetBuffer() - that returns a "writable" pointer, which you don't need.
CString comes with bucketloads of operater overloads.
CString str = "45" ;
int m ;
m = atoi( (const char *) str);
using System.Beer;
|
|
|
|
|
The cast is not necessary. This will suffice:
int m = atoi(str);

Indeed. But it's harmless and illustrates the point that atio() wants a *const* char *.
I ought to have written that. I'm lazy.

Hi,
I am working with Win32 serial communication.
I have an unsigned char array with data
Unsigned char data[7];
data[6] = 0xC0;
data[5] = 0x00;
data[4] = 0x00;
data[3] = 0x00;
data[2] = 0x03;
data[1] = 0x00;
data[0] = 0xA0;
CString szMsg;
szMsg.Format("%02X,%02X,%02X,%02X,%02X,%02X,%02X", data[0], data[1], data[2], data[3], data[4],data[5], data[6]);
OutputDebugString(szMsg);
//A0,00,03,00,00,00,C0 -------------Actual data
I want to append “\r\n” to these characters after copying them into the buffer for writing on the port. When I send data to port I append “\r\n”, so that while recieving, if I get more than two lines I can seperate them out by searching for new line.
Send(data);
I had to use functions like _mbslen , _mbscpy and _mbscat because of unsigned char data type.
I did this way:
bool CPanelInterface::Send( unsigned char* cBuffer)
{
size_t len = _mbslen(cBuffer)+2;
//It is showing len = 3 -------I did not understand this. When I passed a 7 byte array, why it is showing the length as 3.
CString szMsg;
szMsg.Format("%02X%02X%02X%02X%02X%02X%02X", cBuffer[0], cBuffer[1], cBuffer[2],cBuffer[3], cBuffer[4], cBuffer[5], cBuffer[6]);
OutputDebugString("\n ");
OutputDebugString("Send1---");
OutputDebugString(szMsg);
//Send1---A00003000000C0 ---------------correct
unsigned char* myBuffer = new unsigned char[len];
_mbscpy(myBuffer, cBuffer);
The data is getting corrupted here after this call to _mbscpy.
CString szMsg;
szMsg.Empty();
szMsg.Format("%02X%02X%02X%02X%02X%02X%02X", myBuffer[0], myBuffer[1], myBuffer[2],myBuffer[3], myBuffer[4], myBuffer[5], myBuffer[6]);
OutputDebugString("\n ");
OutputDebugString("Send2---");
OutputDebugString(szMsg);
//Send2---A000CDFDFDFDFD -------------- Corrupted myBuffer -> data after copy
szMsg.Empty();
szMsg.Format("%02X%02X%02X%02X%02X%02X%02X", cBuffer[0], cBuffer[1], cBuffer[2],cBuffer[3], cBuffer[4], cBuffer[5], cBuffer[6]);
OutputDebugString("\n ");
OutputDebugString("Send3 After Copy---");
OutputDebugString(szMsg);
//Send3 After Copy---A00003000000C0 ------------------ cBuffer is still having correct data
unsigned char endch[2];
endch[0]= '\r';//\n"};
endch[1]= '\n';
_mbscat(myBuffer, endch);
szMsg.Empty();
szMsg.Format("%02X%02X%02X%02X%02X%02X%02X", myBuffer[0], myBuffer[1], myBuffer[2],myBuffer[3], myBuffer[4], myBuffer[5], myBuffer[6]);
OutputDebugString("\n ");
OutputDebugString("Send4---");
OutputDebugString(szMsg);
//Send4---A00D0ACCCCD010----------_ mbscat is also not working properly.
if(!serial.SendData(myBuffer, len))
{
MessageBox(NULL, "Write Failed", "Serial Library Interaface", 0);
myBuffer = NULL;
delete myBuffer;
return false;
}
serial.FlushPort();
myBuffer = NULL;
delete myBuffer;
return true;
}
I am stuck here and am unable to understand why my buffer is getting corrupted after using these string functions. can anyone please help me to solve this problem.
Thanks in anticipation of information.

I'm not really motivated to go through your code line by line.
But I don't get why you're working with both CString and also char * buffers and libc string functions. I'd say stick with one or the other.
using _mbs???() functions is wrong. They're for wide character sets, and you're dealing with byte data.
1. You want a \r\n at the end of your string? Put it in your format string:-
CString szMsg;
szMsg.Format("%02X%02X%02X%02X%02X%02X%02X<font color="red">\r\n</font>", cBuffer[0], cBuffer[1], cBuffer[2],cBuffer[3], cBuffer[4], cBuffer[5], cBuffer[6]);
or, you can use CString's "+" operater to join two strings:-
CString szMsg;
szMsg.Format("%02X%02X%02X%02X%02X%02X%02X", cBuffer[0], cBuffer[1], cBuffer[2],cBuffer[3], cBuffer[4], cBuffer[5], cBuffer[6]);
szMsg = szMsg + "\r\n";
2. Not using _mbscpy
I don't know where you get your "len" variable from. But use strcpy() instead.
unsigned char* myBuffer = new unsigned char[len];
strcpy(myBuffer, cBuffer);
Those things should help.

Hello everyone:
I program code in Japanese OS. And I found that CEdit::LineLength() can not return total bytes of one line. The function returns total character number of one line.
Example:
1. "1234日本90" --->>> LineLength -> 8
2. "1234567890" --->>> LineLength -> 10
About Example 1, it should return 10 but the result is 8.
Is it right? or I need to set up something?
Thanks.

I do not know an exact answer to your problem, but I'm fairly certain it is Unicode related. With Unicode, each character consumes two bytes, which is why example 1 is two bytes short of what you expect. You might try defining both UNICODE and _UNICODE in your project's stdafx.h file.

I am trying to encrypt a video file (any format)using my own algorithm. I want to know how could I get the data of video file. Is there any class or library available that can give me direct access to video file data. Is there any available DirectShow Class Library available for directly accessing video data?
I don't want to change the header of the file. Just need direct access to the video data (in binary) so that i can apply my encryption algorithm on it.
Thanks
Naveed

If you wish to use DirectShow, then the method is to generate a playback graph that first has a source filter (the video file), then possible decoding filters to get raw video data, then a Sample Grabber filter, which allows access to the samples passing through the graph and a Null Renderer filter, which will discard the original samples.
Then, using the Sample Grabber, grab every frame of the video, pass it through your encoding algorithm, and manually write a file. The filter provides a callback for an user-specified function whenever it receives a sample, so no data will be lost. Unfortunately, as far as I know, you cannot reinsert your encoded samples back into the same graph. You must manually write a file header and the actual file.
The final (and most difficult) option is to write a DirectShow filter using your algorithm. This is very similar to writing an encoding/decoding filter. The raw data comes from the input pin, is encrypted, and passes from the output pin. You can then insert an AVI Mux filter and a file writer filter to have a fully functioning encrypting graph. This is the most efficient way, but may require some learning and trial & error procedures.

Hello:
I have an application that makes heavy use of many double buffered images that are dynamicly updated in real time (GDI). I have created the compatible DC's and CBitmaps. I think that I have properly closed all resources as soon as I use them. However when I reach around 64 of these double buffered DC's my application hard-crashes windows with a reboot, and a message in system font that resources have been used up. Is there a limit to the DC stored or is this a symptom of something I am not releasing properly?
|
|
|
|
|
There is a limit to how many DCs can be created at one time, and you just found it  . You must use as few DCs as possible, and release them as soon as you're finished with them. You don't need a single DC per bitmap, just select the bitmaps into one DC as you need them. I recommend creating and destroying the compatible DC each time in your drawing method, rather than creating and storing it for later use.

Does DrawDragRect go by current window location or total scroll window location? Cause right now when I scroll it would continue to display page 1 stuff.
|
|
|
|
|
I was fairly disappointed with DrawDragRect - you must do alot of work yourself and clean up once the mouse button is released. There is a function to translate and scale co-ordinates relative to the upper left corner of the client window, which I remember you must use.
|
|
|
|
|
Any chance you know which function is that? I am searching for it I can't find it.
There aren't too many DrawDragRect example floating around on the net.

I'm trying to print an image with DrawImage (GDI+ library).
graphics.DrawImage(pImage, rfDraw, rfPic.X, rfPic.Y, rfPic.Width, rfPic.Height, UnitPixel);
The graphics object is constructed with a printer device context.
The <rect>rfPic rectangle is the source area to draw from, e.g. (0, 0, 1000, 800) pixels. The rfDraw rectangle is the destination area to draw to, e.g. (100, 100, 6100, 4900) pixels. On a 600 x 600 dpi printer, this should result in a 10 x 8 inch image.
However, the image is blown up to gigantic proportions, so I only see a small magnified portion of the image. Can someone tell me why?
Drawing to screen works fine (same code, different values). I tried other unit values, setting the page scale and a lot of other things. No luck.
Can someone help me please?
Thanks,
giannibal
