"Add/Remove is impossible, because the code element 'C...' is read only"

I am making a SDI application in that i have used splitter control in that splitter contol i have made a list control using this code
CListCtrl& lc = GetListCtrl();
lc.ModifyStyle(0,LVS_REPORT);
lc.InsertColumn(0, _T("Name"), LVCFMT_LEFT,50);
LVCOLUMN col;
col.mask = LVCF_FMT | LVCF_TEXT;
col.pszText = _T("Monitor Type");
col.fmt = LVCFMT_LEFT;
lc.InsertColumn(1, &col);
lc.SetColumnWidth(1,150);
lc.InsertColumn(2, _T("Host(Url)"), LVCFMT_LEFT,150);
In my application when i click a toolbar button a dialog box opens up and the user has to fill the values in that dialog boxes columns and when the user will press the save button then those values will be saved in previous list control
Now the prolem is i am calling object of that list ctrl class in my dialog boxes class its giving an error degub assertion failed when i run the program
and when i use dialog variables in list ctrl class it does not add up the values to list ctrl
how to do it

Perhaps, if you include the piece of code decribed above, our lives will be easier. Moreover, please, surround your code with preformatting tags:

In a DLL function,I need to call a exe and pass parameters to that exe.
Actually the parameters are to be used in a function of the exe file.
In Dll function
<br />
extern "C" __declspec(dllexport) PlotWave(double *Data,int nData,int mode)<br />
{<br />
HWND hExeWnd=FindWindow(NULL,"WFP"); <br />
if(hExeWnd)<br />
{ <br />
SetForegroundWindow(hExeWnd);<br />
ShowWindow(hExeWnd,SW_SHOW);<br />
} <br />
else<br />
ShellExecute(NULL,"open","C:\\wfp.exe",NULL,NULL,SW_SHOW);<br />
<br />
}<br />
Now I have to pass those parameters(double*,int,int) to the wfp.exe.
I know in ShellExecute we can pass parameter to the file we want to open.
But how can my wfp.exe accept that parameters.
What should I write in my wfp.exe to do so.
I tried using SendMessage(hExeWnd,WM_PLOTWAVE,0,0).
My wfp.exe only can recieve the message but how to get the parameters
because SendMessages() accepts only WPARAM and LPARAM.
Help please!

Look up GetCommandLine and CommandLineToArgv.

Entry point function of your exe(main,winmain etc.) will take care of that.
You need to Parse its parameters. In case of windows application you can use GetCommandLine, as suggested earlier.

In this case, you can wrap required information in structure. i.e.
class myInfo
{
double *m_pDouble;
int m_iFirst;
int m_iSecond;
public:
myInfo():m_pDouble(NULL),m_iFirst(0),m_iSecond(0)
{
}
};
myInfo *pSendInfo = new myInfo;
SendMessage(hExeWnd,WM_PLOTWAVE,(WPARAM)pSendInfo,0);
Now, in command handler you can unwrap the information.

Thanks for your replies.
As I need to pass a double pointer as a parameter,
ShellExecute would not be working.
As suggested by prasad,I used SendMessage() function.
In the DLL function
<br />
extern "C" __declspec(dllexport) void __stdcall PlotWaveForm(double *Data,int <br />
nData,int Mode)<br />
{<br />
double *pData=new double;
SendMessage(hExeWnd,WM_PLOTWAVE,(WPARAM)pData,0);<br />
delete pData;<br />
}<br />
In the recieving application(.exe),I cast the pData to double* as
<br />
void CWFPDlg::PlotWave(UINT Msg,WPARAM wparam,LPARAM lparam)<br />
{<br />
double *WaveData=NULL;<br />
WaveData=(double*)wparam;<br />
}<br />
Since wparam is a pointer to double array,
I used WaveData[i] to get values to plot the wave,but the values
in the array are not correct.What's the problem.

There should not be any problem.
poda123 wrote: double *pData=new double;//just checked for one parameter
SendMessage(hExeWnd,WM_PLOTWAVE,(WPARAM)pData,0);
delete pData;
I hope you have passed some value in array.
poda123 wrote: double *WaveData=NULL;
WaveData=(double*)wparam;
Does WaveData showing some garbage or showing just NULL.
If its showing garbage value; try commenting delete pData; statement after SendMessage.

You can also use WM_COPY message during execution or use shared memory

Plz provide me some link related to mfc collection classes especially map classes

thnax alot for the link.
are there any good articles in code project for easy understanding?
|

A google search on "mfc collection classes" yields links to many articles.
The MFC/ATL documentation for each class is pretty good too, with code samples.

Here is one[^].
BTW a simple search with Google with keyword as "MFC Collection classes" should have helped you much better.

Hi All,
I use a CStatic to show a bitmap in a dialog. The bitmap is a thumbnail of a file. Everytime when a file is chosen, the code call CStattic::SetBitmap to associates a new bitmap with the static control and the bitmap will be shown out immediately. But I minimize the dialog and maximize the dialog again, the bitmap in the CStatic control can't be shown out.
Do you know how to show the picture out again when the dialog is maximized?
thanks,
Eric

Sounds like you've got a problem with the control not repainting itself. What if you call Invalidate() on the CStatic when your form is shown ? ( NOte : this should have happened by itself )

Is the bitmap getting deleted after you set it?
If you're using CBitmap, and it goes out of scope, it will delete the gdi object.

The code is like this:
{
CBitmap tempBitmap;
...
HBITMAP hBitmap = HBITMAP(tempBitmap);
m_picHolder.SetBitmap(hBitmap);
...
}
When call SetBitmap again, the bitmap can be shown out. But it will disappear after minimize and maximize the dialog.
Thanks,
Eric

You need to create on heap , using new.
Or , make CBitmap object, as member variable along with m_picHolder.
