I have created an image transfer system using the UK GSM network. When the send and receive ends are both on my desk (both modems in the same GSM cell), then I have no problems at all, the system and the software work perfectly.
However, as soon as the ends are separated by any reasonable distance (in to a new GSM cell) the system falls over. Having done some extensive playing aroundtesting I have managed to discover that the modems response to dialing any out of cell number is 'NO CARRIER'. Unfortunately I have very little comm.s experience and even less experience with GSM comm.s.
I can write the most clever code in the world, but if I can't get a call to connect it's a waste. Does anyone have any ideas as to what's occurring here?

How do I do it? :-P
I want to enable copying from a CScrollView derived class the selected data in text format. The clipboard stuff I can do, but what is bugging me is whether I really have to code the selection stuff myself.

Yes, you'll have to do that yourself. What kind of information are you displaying in CYourView?

Thanks for your answer, even though it is not what I wanted to hear  .

You may consider switching to CEditView or CRichEditView then.

Hello,
I am writing a dialog based application in VC++ 6.0.
I need to execute a dos program at one point in the program and use the file generated by the DOS program. Please tell me if you know how to execute a DOS program from my VC++ code. Thanks !!
I really appreciate your input on this.
Thanks you!
Sincerely,
Anjum.

Still using old 16bit DOS apps? Puh! 
However, a 16bit app is started as any other app either using ShellExecute(Ex)() or CreateProcess() APIs.

Hello,
I am writing a dialog based application using VC++ 6.0. It is almost complete. Now I need to change the color of all the dialog boxes and all the buttons on it from normal Grey to Some other color. I am using the funtion SetDialogBkColor() in my initInstance to change the background color .. but all the buttons etc. remain grey. Pleas suggest a way that I can change the color of all the buttons to something other color other than grey.
I really appreciate your effor in solving this problem.
Thanks!
Sincerely,
anjum.

the standard window buttons can't be changed in color... however they can be owner-drawn... check some articles on this site ... Controls - Buttons for example, is a section which contains lots of good info on this subject

Hi,
How can i read the unicode string from a file line by line?
Text contents will be something like this:
English string chines string
Thanks
Neha
|
|
|
|

first you check the first two bytes of the file... if they are 0xFF and 0xFE, respectively, the file is little endian unicode... meaning that every character in the string is two bytes and that the value (up to 65535) is a little endian "short"... if the first two bytes are 0xFE and 0xFF then the file is big endian unicode, meaning that each character is a big endian "short" value... if the first two bytes are anything else, it's not unicode
NOTE: i'm not sure about UTF-8, i never figured out the byte pattern for that format

In release build my exe is crashing while invoking a dialog, its crashing in ::CreateDialogIndirect() function.
Can anybody help me.
I got two Extention dlls, one DllOne.dll and another DllTwo.dll. I am handling menu clicks into DllOne.dll's mainfrm.cpp. into a function called Fun1(). In Fun1() i am trying to invoke a dialog from DllTwo.dll. There are two Dialogs into DllTwo.dll, For first Dialog its working fine in Release Build but the second one is not working (crashing into CreateDialogIndirect()). Both of these dialogs are working perfect in Deug build. Please Help
Thanks

Try using AFX_MANAGE_STATE(AfxGetStaticModuleState()); at the beginning of the dll function in which you are aceessing the dialog.

Hi all,

Hello,
I have never given any beautiful look to my apps. since they are used to move machines and to control their movements.
Now that I have some time I would do it, but I don't know if I can use icons from the Microsoft library "SHELL32.dll" and so others...
Is it legal to use them?
best regards.

I have a windows gdi region (or even a gdi+ region) and I am trying to determine an intersection point on its edge from a line constructed between the region's centre and another point outside of the region. Is this possible?
I know there are functions to determine whether or not a point lies within a region or not, but this only leaves me with the brute force method. I could iterate pixel by pixel from the outlying point up to the region's centre point until ::PtInRegion() changes from returning true to returning false. But this seems rather innefficient.
Please help!
Thankx,
swine

Thanks but that's the easy part!  The hard part is to do it with any given region (this includes regions with curves and diagonal lines, etcetera)...
