Can you give me exmple how to write a messsage handler ,
I did it only with the class wizard of mfc,
and this is the first time I need to add a timer
to a class that don't connected to any window,
even if I creat a fictive window like dialog box the SetTimer(...)
works only if the dialog is opened by DoModal.
thanks

I see all kinds of articles and documents on tokens using strtok_s, but none of them show how to get or capture the actual value of a token.
It looks like a token is a pointer, to a place in a char array. but it doesn't seem to give you the length. In the autos, it looks like an array of chars, but I know better now.
char *szServerName[50] = {""};
szServerName = token2;
would be invalid,
I figured out how to step through the source char array in a name value pair
eg. ServerName, DELL760
token1 = ServerName
token2 = DELL760
but I can't figure out how to capture the values. Plus you can't run token1 in a switch, because there is nothing to compare to.
void CA_SQLServer_Scan::_process_SQL_BufferData( std::vector<char> pData, int pLength )
{
int msgLength = pData.size();
char *szWords = new char[msgLength+1];
for (int i = 0; i < msgLength; i++) {
szWords[i] = pData[i];
}
szWords[ pData.size() ] = '\0';
char seps[] = ";";
char *token1, *next_token1, *token2, *next_token2;
char *szServerName[50] = {""};
char *szInstanceName[50] = {""};
char *szClustered[5] = {""};
char *szVersion[25] = {""};
char *szTCP[5] = {""};
char *szNP[80] = {""};
if ( strcmp( szWords, "ServerName" ) !=0 &&
strcmp( szWords, "InstanceName" ) !=0 &&
strcmp( szWords, "Version" ) !=0)
{
token1 = strtok_s( szWords, seps, &next_token1);
token2 = strtok_s( next_token1, seps, &next_token1);
while (token1 != NULL || token2 !=NULL)
{
if ( token1 !=NULL || token2 !=NULL )
{
token1 = strtok_s( next_token1, seps, &next_token2);
token2 = strtok_s( next_token2, seps, &next_token1);
}
}
}
delete [] szWords;
}

That won't work either since szServerName is defined as an array of pointers.

would be invalid,
Surely it's invalid. You just need to use strcpy() to copy the value from the token. And compare it with the required value.

I think there is quite a lot you don't understand unfortunately; this is a bit of a mess.
You need to understand the difference between a char* and a char* []. You are also using a vector in your function when you are just passing a null-terminated string. Given your array of SQL information you know that it is in pairs of strings <keyword>;<value> so you just need to split the string into it's constituent parts and process each keyword as required. Something like:
void CA_SQLServer_Scan::_process_SQL_BufferData(char* pszData)
{
char *token1, *nextToken, *token2;
char seps[] = ";";
char *szServerName = NULL;
char *szInstanceName = NULL;
char *szVersion = NULL;
token1 = strtok_s(pszData, seps, &nextToken);
do {
token2 = strtok_s(NULL, seps, &nextToken);
if (strcmp(token1, "ServerName") == 0)
szServerName = token2;
else if (strcmp(token1, "InstanceName") == 0)
szInstanceName = token2;
else if (strcmp(token1, "Version") == 0)
szVersion = token2;
if (token2 == NULL)
break;
token1 = strtok_s(NULL, seps, &nextToken);
} while (TRUE);

I had my bubble burst last night by another comment on my experimental code.
I tried if token1 == "ServerName", but it always came out false. Didn't think to use strcmp on the value. I tried to do a switch to, Switch (token1) but it wasn't valid.
Well like I said, I'm only 4 weeks into this. I think once I get a clear understanding of working with data in c++, everyone will see better cleaner code from me.
There alot of people from this technology company pushing me toward using vectors for everything, but I do really need to understand the char first.
Thanks in advance, let me soak it in for an hour.

Sorry to have to do it again, but I am finding it difficult to understand why you are working on this project when your knowledge of C/C++ is at the level it is. You seem to be struggling with some very basic concepts, which are vital to get your program to work. I would agree that using vectors (and other STL classes) would be a good thing but you really need to have a good grasp of the basics first.

I have SDI application and two panes. I would like bottom pane to have fixed size (instead of top pane having it). When user moves splitting line bottom pane should maintain newly fixed size. When window is resized, so that there is no room for top pane, bottom pane should occupy whole area. When window is enlarged again bottom pane should occupy last fixed size (ie. enlarge to a certain point and then stay fixed). Standard CSplitterWnd does not have this functionality, and last pane is always expanded to the end, and all previous panes are fixed. I was searching here for appropriate splitter class, but no luck so far. Maybe I'm missing something obvious. Is there a ready made solution? How should I solve this problem?

In linked article there is no mention of fixing the size of particular pane. The only advantage of featured class is that it works on CDialog, and that it uses registry. I've checked all other splitting classes, but either required functionality does not exist, or I can't find it. Hence the original question.

handle the WM_SIZE message in the parent class (parent of splitter), then size each splitter panel appropriately.

My current solution is a monstrosity of a workaround that includes CMainFrame::OnSize handler, and a class derived from CSplitterWnd that exposes "ideal" sizes (you can set them but can't get them), and reroutes TrackRowSize/TrackColumnSize to CMainFrame so that proper size fiddling can be achieved. I am not proud of it, but it seems to be working for now.

First read Minimum size splitter
then try:
CSplitterWnd::SetRowInfo (horizontal)
Call this member function to set a new minimum height and ideal height for a row. The row minimum value determines when the row will be too small to be fully displayed.
When the framework displays the splitter window, it lays out the panes in columns and rows according to their ideal dimensions, working from the upper-left to the lower-right corner of the splitter window's client area.
void CMyFrame::OnSize(UINT nType, int cx, int cy)
{
if(::IsWindow(m_wndSplitter.m_hWnd) && ::IsWindow(m_wndSplitter2.m_hWnd))
{
m_wndSplitter.SetRowInfo(0, cy*2/3, 10);
m_wndSplitter.SetRowInfo(1, cy/3, 10);
m_wndSplitter2.SetColumnInfo(0, cx/4, 10);
m_wndSplitter2.SetColumnInfo(1, cx*3/4, 10);
RecalcLayout();
}
}
CSplitterWnd::SetColumnInfo (verticle)
Call this member function to set a new minimum width and ideal width for a column. The column minimum value determines when the column will be too small to be fully displayed.
When the framework displays the splitter window, it lays out the panes in columns and rows according to their ideal dimensions, working from the upper-left to the lower-right corner of the splitter window's client area.
Example
void CChildFrame::OnSize(UINT nType, int cx, int cy)
{
CMDIChildWnd::OnSize(nType, cx, cy);
CRect rect;
GetWindowRect( &rect );
if( m_bSplitterCreated )
{
m_wndSplitter.SetColumnInfo(0, rect.Width()/2, 10);
m_wndSplitter.SetColumnInfo(1, rect.Width()/2, 10);
m_wndSplitter.RecalcLayout();
}
}
CSplitterWnd::RecalcLayout
Call this member function to correctly redisplay the splitter window after you have adjusted row and column sizes with the SetRowInfo and SetColumnInfo member functions. If you change row and column sizes as part of the creation process before the splitter window is visible, it is not necessary to call this member function.

Thank you for MSDN reference, but my goal has nothing to do with splitter's minimum size. The ideal solution would be the one that has different RecalcLayout algorithm that recalculates layout the way I want it, having in mind what panes have fixed size (until user changes it), and what panes should be resized when the window is resized. Currently only the last pane is resized (the rightmost, or the "bottomest"), and all previous are fixed. Along with RecalcLayout rewrite there should be an update in TrackRowSize/TrackColumnSize so that fixed panes remain fixed (unless the user is resizing one just now), and resizable panes get resized to compensate for current pane reconfiguration.

I wonder if what you want to use is CDockablePane.
The MFC "Visual Studio" Project style (available in VS2010) demonstrates usage of the CDockablePane and has the behavior you're describing.

Funny this. I created project from VS template and tested it a bit. If you shrink the window to a minimum then left and right dockable panes will also shrink and will not grow back. Then I tried the same thing with Visual Studio itself and the same thing happens. Dockable panes shrink, but do not grow back. But at least we have middle area that takes all the non-fixed space.
If those dockable panes could be prevented from undocking, hiding, auto-hiding, and if they could be made without titlebars, so that they resemble another client area, then I would have something close to original idea. But without the panes growing back when there's available space.

how to add the help file in an SDI Application i tried with this

MSDN says:
The following example calls the HH_DISPLAY_TOPIC command
to open the help file named Help.chm and display
its default topic in the help window named Mainwin.
Generally, the help window specified in this command is a standard HTML Help Viewer.
MSDN Example
HWND hwnd =
HtmlHelp(
GetDesktopWindow(),
"c:\\Help.chm::/Intro.htm>Mainwin",
HH_DISPLAY_TOPIC,
NULL) ;

hi i have use the GetCurrentDirectory now i want to change the Directory with SetCurrentDirectory can any one explain with Example
thanks

Well, the MSDN can, as always: SetCurrentDirectory[^]
If after reading the article something is still unclear, please post a detailed description (with source code showing what you have tried). It's hard to target a specific problem with a general question...
