when com5 is power on,i open com5(OK).
when com5 is power off,i open com5(very slow my application)

Have you tried setting these timeouts to smaller numbers.
CommTimeOuts.ReadIntervalTimeout = 0xFFFFFFFF;
CommTimeOuts.ReadTotalTimeoutMultiplier = 0;
CommTimeOuts.ReadTotalTimeoutConstant = 0;
CommTimeOuts.WriteTotalTimeoutMultiplier = 0;
CommTimeOuts.WriteTotalTimeoutConstant = 5000;

hello can u tell me how 2 create xml in vc++ using MSXML 3.0
thx

Please Read Documentation of IXMLDocument in your local copy of MSDN,you will get all your answers to your problem there.
Or you can manully create XML (by following XML standards) through your coding as you have to pass it Remote Server.
During receiving and parsing the XML,use the coding I have given to you in my last POST to you,

Hello,
Is there an easy way to port an ActiveX control (partially based on MFC) back to a plain MFC control?
I'm well aware the good side of ActiveX controls, but here, due to the versioning nightmare and also due that it is poorly written, I will be difficult to continue to use as-is. (Written Quick  &Dirty by a programmer that left the company and now I need to maintain it .
Also, adding new interfaces, or even changing the current interfaces this control has, may corrupt its use on other projects that must run in parallel.
For this, I thought that the best is move back to MFC, so every project has its tailored control and it will not deppend on how/where the ActiveX control is registered.
The ActiveX control is a simple charting control that allows to display constellation, also works as a "scope" control.
Any hint?

Hi all,
Iam very new to windows programming stuff.
I require to add resolution modes in display settings of the desktop on Windows98 plateform.
Where as in windows 2K/XP/NT v have facility to check and uncheck the option " Hide the modes that this monitor cannot display" which adds many resolution modes to change for all display cards..or.. change the value 0/1 of "pruning mode" key in registry path HKLM\SYSTEM\CONTOLSET001\SERVICES\IALM\DEVICE0 ( intel graphics card).
i keep on changing cards like ATI,Nvedia,matrox,etc....
but in windows 98 there no facility in registry as such.
note:
On WIN98 i found one Modes folder in regisry HKLM\SYSTEM\CURRENTCONTROLSET\CLASS\DISPLAY\active driver e.g 0000\Modes
here i can see arround 37 resolution modes in which some are not shown in display settings.
i would like to add these modes into display settings options and customer to choose from that.
if anybody knows requested to help.

My application can able to open the *.xlc format file and shows the content in the file.
My Question was, How can I open the *.xlc file from windows explorer Open With option? How can I pass this *.xlc file parameter to the file to open the file with my application.
Please help me in this...
|

|
|

Are you looking to register the *.xlc with your application. If so the following lonk can help you. file association [^]
or look WinApp::RegisterShellFileTypes.

I have two modules.
1. is a calibration modul, in which I am doing calibration of the system(that is doing some setting) and storing those
values to .INI file.
Now,
2. in second module I want to initialise this module or read some values from that .INI file which is set by first module.
I have some Idea that I need to use
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
but how to pass values to above class?
can any one please help me out. "or" give any sample code.

Unless you are against using __argc and __argv, I would suggest Paul DiLascia's CCommandLineInfoEx class.

hi!
I´m a little newbie. I´m doing a program for my final career project. I´m using a derivied CListCtrl class that is doing its job in a perfect way. But, I have seen in some programs and in windows XP folders that if you select various files with the mouse, the mouse draws a blue rectangle selection. If you does the selection in desktop, this rectangle is transparent (only borders).
More than a question, it is a curiosity...how could I do this? I have reviewed the MSDN and I haven´t found anything.
thanks in advance
(sorry for my poor english

In the MFC dialog editor, set the Selection Type to "Extended"

Hello,
Could anyone recommend an elegant way to insert a CBitmap (HBITMAP) object into a raw CRichEditCtrl (WITHOUT the doc/view architecure)? IOW, I need to create an OLE object from the bitmap handle (actually I am using GDI+ to generate this bitmap).
Regards,
BB
|
|
|
|
|
|
OK, but this HOWTO uses OleCreateFromFile to insert a bitmap FILE into the control, whereas I need to insert a dynamically created HBITMAP without saving it.
Regards,
BB

|
|
how about switch to OleCreateFromData?

Hi
I started learning MFC ... and I have some really stupid questions.
I hope someone can help me.
How can I pass on arguments to the program? In C or C++ I had the main function for this purpose but here ....Can I use InitInstance??
Basically what I want is my program to run like this:
MyApp.exe NrOfParam param param.... (list of parameters)
It's a simple dialog based application.
Second: can I have global variables accesible from every file of my project?
I'd be very grateful for any kind of help.

I am try to calculate 2D convolution and extract the central matrix of the convolution result. Here is my c++ code:
//create the kernel matrix
mxArray *mxKernel = mxCreateNumericMatrix(3, 3, mxDOUBLE_CLASS, mxREAL);
double *Kernel = mxGetPr(mxKernel);
//set the kernel
Kernel[0] = 2; Kernel[3] = 3; Kernel[6] = 1;
Kernel[1] = 0; Kernel[4] = 2; Kernel[7] = 3;
Kernel[2] = 4; Kernel[5] = 2; Kernel[8] = 1;
int Mk = mxGetM(mxKernel);//row of kernel
int Nk = mxGetN(mxKernel);//column of kernel
int M = mxGetM(ImportMatrix);//row of input matrix
int N = mxGetN(ImportMatrix);//column of input matrix
Input = mxGetPr(ImportMatrix);
//create the result matrix with elements 0
ExportMatrix = mxCreateDoubleMatrix(M, N, mxREAL);
Output = mxGetPr(ExportMatrix);
//do the algotithm
int i, j, k1, k2;
for ( i = Mk/2 + 1; i <= M + Mk/2; i++ )//output row
{
for ( j = Nk/2 + 1; j <= N + Nk/2; j++ )//output column
{
for ( k1 = 1; k1 <= Mk; k1++ )
{
for ( k2 = 1; k2 <= Nk; k2++ )
{
if ( ( i + Mk/2 + 1 - k1 >= 1
&& j + Nk/2 + 1 - k2 >= 1)
&& ( i + Mk/2 + 1 - k1 <= M
&& j + Nk/2 + 1 - k2 <= N) )
{
Output[( i - Mk/2 - 1 ) + ( j - Nk/2 - 1 ) * M] +=
Kernel[( k1 - 1 ) + ( k2 - 1 ) * Mk] *
Input[( i - k1 ) + ( j - k2 ) * M];
}
}
}
}
}
my code is quite slow and it is even slower than performing convolution with no extraction of central part. (this means that it is slower even the for loop is less in iterations)
Could anyone point out that how could I optimize this code?
Thanks very much.

Calculate the middle value first - it is being calculated every time here.

There's also stuff here you could calculate before the k1/k2 loops, anything you can calculate once and put in a variable, do it.
I've not taken time to see if the overall approach could change, but those two things should make some difference.
