I had a similar issue with a Siemens software (WinCC), the resolution of my computer is optimized to 1900x1280, the problem is that the computer changed automatically the DPI property of the monitor to make the icons and the fonts more readable. The problem came when I started to develope a Touch Pannel, the things I was seeing in the simulation locally, where not fitting the things the panel showed when transferring. It was because of that DPI property. Now I have to work with such a hugh resolution and the normal size of system font (96 DPI) so I am virtually f...ing my eyes to read things in this laptop.
I know that is not related with C++ but it could be a cause, take a look on that. I don't know if that property can be obtained dinamically, but I guess yes. Afterwards you will be able to adapt the size of elements according to that. But for that you should wait to the answer of CP-Gurus or a fitter user than me.
Hope it helps.
Regards.

When I use the following codes to calculate values, I always get different results for Debug and Release config.
Do you know what causes the difference, and which result is correct?
Part of the codes are as following:
========================================================================
GradeData tempGradeDataGD0;
GradeDataCRC tempGradeDataCRC;
unsigned long Index = 0, Orientation = 0, lcv = 0;
unsigned short SegmentID = 0, prevSegID = 0;
double Offset = 0, prevOffset = 0;
double Grade = 0, prevGrade = 0;
double SegLength = 0;
Input_File >> Index >> Grade >> SegmentID >> SegLength >> Offset >> Orientation;
Input_File.getline(tempString, 256, '\n');
tempGradeDataGD0.Distance = (unsigned long)floor(Offset * 256);
tempGradeCompDeceleration = (float)(2 + (2 * 9.81 * RoundToHundreths(Grade) / 100));
tempGradeDataGD0.Deceleration = (unsigned long)floor(tempGradeCompDeceleration * 256);
if(SegmentID == prevSegID)
deltaGradeZnOff = (float)(Offset - prevOffset); // float to ensure the precision.
else
deltaGradeZnOff = (float)Offset;
tempGradeCompVelocitySquare = tempGradeCompDeceleration * deltaGradeZnOff;
tempGradeDataGD0.VelocitySquare = (unsigned long)floor(tempGradeCompVelocitySquare * 256) * 256;
=======================================================================
"tempGradeDataGD0.VelocitySquare" always get different values.
Thanks.

Which values ? What is the type of VelocitySquare ?
|
|
|
|
|
*.h:
struct GradeData {
unsigned short SegmentID;
unsigned long Distance;
unsigned long Deceleration;
unsigned long VelocitySquare;
long ScaledGrade;
};
*.cpp
GradeData tempGradeDataGD0;
Question:
"tempGradeDataGD0.VelocitySquare" returns difference values in Debug/Release config mode.

I want to Know about Api who capture all events occur on a dialog / window with the detail of which type of event occur in which object. Next process is to re generate this event one by one what the order user previously done. At the time of capture or regenerate should not disturb the events of each object.
If any body know which Api give the events details, and how to regenerate the event.
It kind of user action recorder/playback mechanism.

How do I find text in CEdit control?
|
|
|
|
|
First get the text in the edit control using the GetWindowText() or GetDlgItemText() functions
Now use the Find() function of the CString to find the string.
|
|
|
|
|
1st get the text through declaring a CString object type than type cast it to string type.
for example
CString strUpper;
CEdit* pEdit = (CEdit*)GetDlgItem(IDC_EDIT);
if (pEdit)
pEdit->GetWindowText(strUpper);
string strNew = (LPCSTR)strUpper;
|

If your CEdit is inside a dialog, you may also map it to a CString variable, call dialog's UpdateData method and then call the CString::Find method on such variable.

Hi,
I have changed my resource file added Dialogs however the change doesn't seem to take
would anyone know Where to specify the .rc file as input to the linker on Visual Studio

UP!

Don't understand it must be somewhere on Porperty Pages -> Linker maybe -> input ???

Hello, I downloaded code written in c which consists of many individual files and routines. I would like to use his code to create a plugin for a 3d animation program.
I program graphics using in C++ and only program for my software's API. To be honest with you, I'm not really sure how to go about it. Would it be possible to create a project as I normally do and import all the c and header files into a c++ project? Or do I have to compile his code? And if I do, what do I compile to? a dll or exe or something else? If I do, how do I access those routines?
As you can probably tell, I am very new at this. Any suggestions will be appreciated.

if you like, you can add the code to your project without change.
and you also can compile the code to a library to use.

Thank you kcynic,
Yes, I'd prefer to add the code to my project.

That implies a DLL, doesn't it?

yes I am creating a dll. My plan is to import all the C routines into my project and call them using my c++ code. Is this possible?

Yes, as long as those routines are exported correctly.

if some of those routines are in the form of a
main (argc, argv) function and these functions are called from another routine, what would be the best way to tie all of them together.
I am assuming the individual main functions are compiled as separate dlls or libs and then work together via some sort of interface?
Sorry for the inexperience, I only program in c++ within a single API.

There is only one main() routine (not plural as you have stated). In any case, it will not exist in your DLL.

All the more reason to start small and work your way into something like a DLL.

Hi David,
You are right. Incorporating C code in my plugin is a big leap for me. But in this case it must be done. I've already learned alot in the process.
Many if not most of the c files have a main(argc, argv) function.
