Why is that. I know that sizeof(int) also gives the number 4. But why I can't use number 4 directly. Any special reason.
I appreciate your help all the time...

If you are coding 16-bit applications, sizeof(int) = 2.
16-bit DOS / Windows
sizeof int: 2
32-bit Windows
sizeof int: 4
64-bit Windows
sizeof int: 4

eg. if you are porting your app to 64 bit machine somewhere in the future the size of an integer will be 8, and you will have to change 4 to 8 in the code to ensure it works correctly...using sizeof ensures no such change will need to be made...

These two statements are writing to the same location. The second one needs to write four bytes past the starting address of tmpBuffer, like.
memcpy(tmpBuffer, &iReq, 4);
memcpy(tmpBuffer+4, strGetName, 6);

Yes my code overwriting the buffer. Any way pointing the buffer make correction to me, as on my second post. It is ok, right....

I've no idea what you are saying here.

I am porting bc3.1 code to VC++.Net. While compiling i am getting the above error in the below line
extern char MC_320_ATP[];
this is in header file and the cpp file contains
char MC_320_ATP[] = "\n#DIR A320\n 4.2 Micro Computer Test %02d.%02d.%04d %02d:%
02d:%02d";
Thanks for your help
Regards

is there a specific reason that there is a newline after this? or has is just been introduced while pasting the code here?
|
|
|
|

For the newline only. It is not from the copy and paste.
|
|
|
|
|
in that case can try removing it or putting a \ at the end, ie:
char MC_320_ATP[] = "\n#DIR A320\n 4.2 Micro Computer Test %02d.%02d.%04d %02d:% \<br />
02d:%02d";

I tried both. It didn't work
|
|
|
|
|
It is showing error in the header file not in the cpp file
|
|
|
|
|
then the error probably lies in the lines above extern char MC_320_ATP[];, check those...
|
|
|
|
|
Hello,
extern const char* MC_320_ATP[]
const char* MC_320_ATP[]
Hope this helps.
Bekir.

this also didn't work. Any other solutions

If the error is happening in the .H file, then the string won;t matter. But the new line rings alarm bells for me. Try making sure all the text is on one line.
Also try using
extern const char *MC_320_API;
instead.
(Both those have been suggested).
Also suggested, but I haven't seen you reply to it...
The problem might not even be on that line of code - it could be higher.
Try commenting out the line, and see if the problem goes away, or if it moves to the next line.
If it moves, then the problem was "bad" code higher up.
(and yes, if you comment out the extern, you will have errors in your cpp files - this is just a test).

thank you all. I figured it out. I missed a semi colon in the previous included header file.

I would like to build a list control with first column used as a “horizontal header"”.
With the first column locked in place the rest of the columns should scroll horizontally as in "standard" list control.
Any suggestions how to do this?
Thanks for reading
Cheers

Meaning that you don't want it to be sizeable?

Yes, sorting is not necessary in my case.
|
|
|
|

Not really, but it can be fixed size if necessary.
I just want to have horizontal reference same as current vertical header is.
For example – if the first column is an "Index" I want to see this column regardless of horizontal scroll position - for easy reference.
I think Lotus 123 used something like that. I have not found it in Excel – not yet.

Understood. I know of no way to do this with a stock control. You might have to resort to two separate controls.

I can't think of any way as such...
But you could always find a solution by changing the problem.
Look at grid controls, either C Maunders classic Grid Control, or the Ultimate Toolbox one.
I found the "Ultimate Toolbox" one a bit of a fiddle to start with, but I think it's more powerful in the end.
(I used the old CGridCtrl before, and have no great need to suffer to change)
