I have a SDI type app with 2 rich edit controls in the view (One for receiving text, and one for sending text).. How can I tell which edit control has the focus so when I do a "ctrl + c" to copy data to the clipboard MainFrame knows which edit control to copy the data from? GetFocus doesn't seem to work.
Any ideas?

Doesn't the richedit handle the clipboard stuff automatically??

Doesn't seem to.. Unless when I create it I need to add something.. Here is how I create the controls..
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
if( !m_wndMonitor.Create(WS_CHILD|WS_VISIBLE|WS_VSCROLL|ES_MULTILINE|ES_READONLY, CRect(), this, 100) )
return -1;
if(!m_wndSendText.Create(WS_CHILD|WS_VISIBLE|WS_VSCROLL|ES_MULTILINE, CRect(), this, 101))
return -1;
m_wndMonitor.ModifyStyleEx(WS_EX_CLIENTEDGE, 0);
m_wndMonitor.SendMessage(WM_SETFONT, (WPARAM)GetStockObject(SYSTEM_FIXED_FONT));
unsigned mask = m_wndMonitor.SendMessage(EM_GETEVENTMASK,0,0);
m_wndMonitor.SendMessage(EM_SETEVENTMASK,0,mask | ENM_LINK);
m_wndMonitor.SendMessage(m_wndMonitor.SetEventMask(ENM_LINK)) ;
m_wndMonitor.SendMessage(EM_AUTOURLDETECT,TRUE,0);
m_wndSendText.ModifyStyleEx(0, WS_EX_STATICEDGE);
m_wndSendText.SendMessage(WM_SETFONT, (WPARAM)GetStockObject(SYSTEM_FIXED_FONT));
return 0;
m_wndMonitor is one rich edit control
m_wndSendText is the other

Hi,
I am trying to convert a small piece of c++ code to c# however I am not familiar with c++.
I have a BSTR called sToChange, and an unsigned int called i
the string sToChange is "ZYX123".
in c++ when i is set to sToEncode[0] (which is 90, the char code for Z) it equals 12:
i = sToEncode[0]
//i now equals 12
in c# the same code i equals 90.
What is happening in the c++ code?
Thanks,
John

90 is ASCII for 'Z'.
IIRC, BSTR's are unicode, right? And they don't necessarily map one to one on ASCII. Have you tried converting the BSTR to a char*? It may also be the case that your BSTR string does not contain what you think it contains.
Do a CString str; str.Format("%S", bstrString); and check the contents of str. I'm assuming you are using MFC or ATL7. If you're using ATL7, try ATLTRACE("%S\n", bstrString); to see what the string contains. And if you're not using MFC, ATL nor ATL7, then use WideCharToMultiByte to convert the BSTR to char*.

I am sending a command out my serial port and waiting for a reply. All replies end with '\r'. I am using WaitCommEvent() with EV_RXFLAG as the event, to wait for a '\r' received.
But with the serial port receive queue, if a '\r' has already been received and is in the queue before I call WaitCommEvent(), will it still return that the event has happened? Or will it timeout? Anyone know?
Thanks,
dan.

I'd say the event will be triggered for buffered characters --otherwise the function is nearly unusable in non-overlapped mode. To make sure, try the following:- Issue the command.
- Wait for a sufficiently long time (say 10 sec.) with
Sleep to make sure the '\r' has been received by the time Sleep returns.
- Call
WaitCommEvent and see what happens.
If WaitCommEvent works the bad way (it doesn't set the event), come back here and we'll try to search for a solution.

Hi,
I'm trying to plot a non linear graph using MSChart. I set up the array and val stores the result of the calculation. However, the graph I plot appears linear and it's plotted val vs val whereas I want index[0] vs val?
double val=0;
double step=0.5;
DWORD numElements[] = {10, 2}
saRet.Create(VT_VARIANT, 2, numElements);
long index[2];
for(index[0]=0; index[0]<10; index[0]++) {
for(index[1]=0; index[1]<2; index[1]++) {
val = index[0]*index[0];
saRet.PutElement(index, COleVariant( val ));
val += step;
}
}
m_chart.SetChartData(saRet.Detach());
m_chart.Refresh();
}
Any ideas?
Cheers

i have an SDI Application with a single view and i need to create new view, that would be a tool modeless window. what should i do?
|
|
|
|
|
An easy solution would be a simple dialog box. Another solution is to create a new window and then show and/or hide it.

Is there a way of checking what versions of controls I am using in my application so I know what to distribute? I selected controls from the toolbox but am not sure which ones they are on my hard disk.
Hopefully, there is something like depends.exe which shows you the control name, location, version, etc. for everything your application is using.
Meanwhile, I have been looking up the CLSIDs in the header file and searching the registry and using OLE/COM object viewer to correlate the files needed.
The reason I'm asking is that even though I have packaged the rich text control, Richtx32.OCX, into my installation program and have registered the control, I am still having problems with my application's release build -- the rich edit control is not visible. I am running Windows 2000 and have tried running the program on Win98 and NT4 but no success.
Are there any other files I need with the richtext control, the flexgrid control, and the tab control besides their OCX counterparts? BTW, I'm a little confused here, I thought I selected a rich edit control (Edit box) into my form view but the CLSID is coming up with RichTx32.ocx.

Have you called AfxInitRichEdit at the beginning of your app?

Yes. Thank you. I've gotten further.
Does anyone know if there are some incompatabilities or limitations with the tab control, flex grid control, or rich text control with Win98 or other OS's???

I think my question was answered today. Someone asked about some problem he/she was having with the MSFlexgrid control and somebody responded that he needed a runtime license for it.

Hi,
I am trying to use ADO and ADOX, and I have included the following #import statements in the stdafx.h file,
#pragma warning(push)
#pragma warning(disable:4146)
#import "C:\Program Files\Common Files\System\ADO\MSADO15.dll" \
rename ("EOF", "EndOfFile")
#import "C:\Program Files\Common Files\System\ADO\msadox.dll"
#pragma warning(pop)
But, when I use the various objects in both the ADO and ADOX package, I need specify ADODB:: and ADOX:: respectively. If I do not specify this then it gives me an error saying that the class is not defined. Can Some one let me know why I am getting such an error.
 
Thanks,
Arthi

Having to prefix the names from these libraries is not a bad thing per se, but if you want to get rid of this obligation, include the following just after the the imports:
using namespace ADODB;
using namespace ADOX; This will pose problems if there are coincident names in the libraries: in those cases, you will have to include the prefix anyway.

I remember in visual basic there was a function for formatting numbers which seperated the number 1763836382 to 1,763,836,382 or 1.763.836.382 depending on the system settings. is there a function that will do that in c++, or is there just a function that will seperate them with a specified character? (i was thinking sprintf but couldn't find that specific flag for digit grouping)
Thanks in advance.

Take a look at the GetNumberFormat in the MSDN. Here's a quote:
"The GetNumberFormat function formats a number string as a number string customized for a specified locale."
So you can use regular sprintf to format the number as a string, and then format that string to the specified locale.

I have a Dialog application with a CTReeCtrl in it . I am buiding an Object Model using the Tree Ctrl but have an XML string associated with each node in the TreeCtrl . I can generate an XML file by traversing all the nodes in the Object Model(TreeCtrl) and just printing the associated Text for a node into a file .
I need to embedd the text information with each node in the TreeCtrl ?
How should I be going about this .
One option is that
For each node in the TreeCtrl i can generate an entry in a look up table that also contains associated text(data). This can be done by generating unique data for each node and by using the SetItemData method for a TreeView Ctrl .
I want to know if there is a better way of doing this !
Please help  ( ( confused:

|

SetItemData() seems the natural way to go, since you want to associate app specific data with each tree node.
