Do this...
CMenu* pSysMenu = GetSystemMenu(FALSE);
pSysMenu->RemoveMenu(SC_MOVE, MF_BYCOMMAND);

Trap WM_NCHITTEST, and make sure you never return HT_CAPTION, and trap WM_SYSCOMMAND, disallowing SC_MOVE.

I have an MFC app that we use Microsoft Visual C++ 6.0 to compile.
I need to get information from a secure website into my app using 2 way SSL. I have tried using MFC's CHtmlView to obtain this information, and was successful; however, my users have all different types of web browsers. For example I have a user that has installed their X.509 certificate into Netscape, but not in Internet Explorer.
I need to somehow make a 2 way SSL connection from my app that uses the default web browser's certificate (which is password protected) and then obtain the body text of the webpage.
I was thinking about maybe trying to use ShellExecute and then obtain the windows handle (the first parameter) and somehow capture the body of the webpage. But I have not seen any examples on the web for this.
Ideally, I would like to not display the default browser, but just use the default browsers certificate store to communicate via 2 way SSL. All I need is to obtain one line of text from this secure webpage (generated from a servlet running on weblogic 8.1)
Thank you for any responses.

I am using Visual C++ 6.0 MFC. I have a tab control with dialog resources as tab pages. If I click on OK or CANCEL buttons the CWnd::SendMessage(WM_COMMAND, wParam, lParam) returns a value of 1 and everything is good. If I click on any other button control (whose resource value is stored in wParam) the CWnd::SendMessage(WM_COMMAND, wParam, lParam) returns a value of 0. Does anyone know what's going on inside the SendMessage() function? Why does the function not recognize the control ID?
Thanks

Did you see MSDN.
From the MSDN:
"The SendMessage function sends the specified message to a window or windows. It calls the window procedure for the specified window and does not return until the window procedure has processed the message."
Syntax
<br />
LRESULT SendMessage(HWND hWnd,<br />
UINT Msg,<br />
WPARAM wParam,<br />
LPARAM lParam);<br />

Thanks to everyone at CodeProject for providing a fantastic resource for programmers.
I am using several comboboxes to navigate through a flat file database of my own construction. Three of these comboboxes are almost identical in structure and function.
When I select a record from the drop down list from two of the combo boxes (all are set in dropdown mode with identical checkboxes), the record is displayed, and the statements:
pComboBox1or2->SetFocus;
pComboBox1or2->SetEditSel(0,-1);
pComboBox1or2->Clear();
clears the edit box of comboboxes 1 and 2 exactly as expected.
However, when I use the same exact lines for combo box 3
pComboBox3->SetFocus;
pComboBox3->SetEditSel(0,-1);
pComboBox3->Clear();
in the same exact point in almost identical code for combobox 3, the edit box of the combobox refuses to clear.
Interestingly, calling the combobox3 lines from the combobox 1 or two functions clears the combobox3 edit box - however this is not adequate as I need to clear the edit box after selecting a record.
While trying to figure this problem out, I placed a 500 iteration loop around the statements for combobox1or2, and noted a flashing edit field - which ended with a blank edit field. When I tried the same thing with the troublesome combobox3, the edit field did not flash (although it took about the same amount of time for the process to finish), and the edit box did not clear.
I have tried everyhting I can think of to make the code for the various boxes as similar as possible, and find it very strange that two of the three comboboxes work as expected, while the third does not.
Any suggestions?
Thanks in advance for your assistance.

your problem is that combox1 and 2 are ok in a same way but combo3 its not same,Right?
|
|
|
|
|
Correct.
All three boxes are almost completely identical in every way - except their behavior. Combo 1 and 2 behave linearly (as expected) every time I try, but combo 3 does not behave linearly much at all, especially with respect to the key behavior of leaving the edit box blank after the record selection is complete.
Completely disabling the edit box, for example painting over it to hide the functinoing edit box underneath might be acceptable. I tried using the Drop List box, as a menas of achieving a secondary goal of preventing user input, but this makes the functioning bozes also fail to clear their edit boxes after record selection.
It is as if combo 3 is not completely switching out of Drop List mode when I change the selector in the resource editor (visual ++ 6.0) except that combo 3 allows changing the edit box text in drop down mode while combo 2 does not allow edit of edit box (in drop list mode).
A good work around would be a means to permanently hide the edit box so it didnot matter if it was not cleared and this would have the added feature of preventing user confusion/text entry in the edit box.
Thanks for your reply.

Possible workaround:
after trying many things such as calling the complete or partial selchange functions that did work, breaking the edit box clearing code out into a separate function etc. I appear to have found something that will work.
Inserting a pComboBox3->Paste(); line like this:
pComboBox3->SetFocus;
pComboBox3->SetEditSel(0,-1);
pComboBox3->Paste;
pComboBox3->SetEditSel(0,-1);
pComboBox3->Clear();
appears to clear the edit box.
It may not be pretty - but, well - neither am I.
Thanks to all of you who considered my problem and especially to WhiteSky who responded.

I'm trying to code a function which returns the number of words in an array, strSentence[100, 1000].
Algorithm:
1. return the first occurrence of strWord.
2. Remove strWord from strSentence.
3. Repeat the above steps until (1) returns no value.
I am using strstr to return the first occurrence of strWord within strSentence. However, the following error is being displayed:
SentenceAr.cpp(94): error C2664: 'strstr' : cannot convert parameter 1 from 'char [100][1000]' to 'const char *'
Code:
int CSentenceAr::HowManyWords(const char strWord[MAX_WORD_LENGTH])
{ char *strCurrentSentence;
ZeroMemory(strCurrentSentence,sizeof(strCurrentSentence));
char *ptrPosition;
for (int iCurrent = 1; iCurrent <= iNumberOfLines; iNumberOfLines++)
{ strcpy(strCurrentSentence, strSentence[iCurrent]);
ptrPosition = strstr(strSentence, strWord);
}
Any work around for this, please?

strstr doesn't know about arrays of arrays of chars, it only knows about arrays of chars.
so... ptrPosition = strstr(strSentence[some_index], strWord);

...
strcpy(strCurrentSentence, strSentence[iCurrent]);
These two statements look suspect as strCurrentSentence does not point to a valid memory address.

This should probably be:
ptrPosition = strstr(strCurrentSentence, strWord);

CSentenceAr.h
int HowManyWords(const char strWord[MAX_WORD_LENGTH]);
CSentenceAr.cpp
int CSentenceAr::HowManyWords(const char strWord[MAX_WORD_LENGTH])
{ char strCurrentSentence;
ZeroMemory(strCurrentSentence,sizeof(strCurrentSentence));
char ptrPosition;
for (int iCurrent = 1; iCurrent <= iNumberOfLines; iNumberOfLines++)
{ strcpy(strCurrentSentence, strSentence[iCurrent]);
ptrPosition = strstr(strSentence, strWord);
}
}
Now I'm getting more errors:
SentenceAr.cpp(89): error C2664: 'memset' : cannot convert parameter 1 from 'char' to 'void *'
SentenceAr.cpp(93): error C2664: 'strcpy' : cannot convert parameter 1 from 'char' to 'char *'

This is not necessary (if strcpy() is to be used later on).

The compiler is telling you exactly what the problem is. Parameter 1 needs to be a char*, but strCurrentSentence is just a char.
jon_80 wrote: SentenceAr.cpp(94): error C2664: 'strstr' : cannot convert parameter 1 from 'char [100][1000]' to 'const char *'
Parameter 1 cannot be a 2D array. Chris showed you a solution. Why did you not use it?

The program uses a fixed array, so I need to work around it. Sorry, but I'm a newbie.
Now I'm getting: SentenceAr.cpp(100): error C2664: 'strcpy' : cannot convert parameter 1 from 'char' to 'char *'
for (int iCurrent = 1; iCurrent <= iNumberOfLines; iNumberOfLines++)
{ //retrieve line of text
strcpy(strCurrentSentence, strSentence[iCurrent]);
ptrCurrentSentence = &strCurrentSentence;
while (bFound == true)
{ ptrPosition = strstr(ptrCurrentSentence, strWord);
if (ptrPosition != NULL)
{ iResult++;
}
else if (ptrPosition = NULL)
{bFound = false;}
}
}
return 0;
}

strCurrentSentence needs to be at least as large as strSentence[iCurrent].

Try this instead:
int CSentenceAr::HowManyWords(const char strWord[MAX_WORD_LENGTH])
{
const char* delimiters = " ,.!?;:\t\r\n()";
char buffer[MAX_WORD_LENGTH] = {0};
memcpy(buffer, strWord, MAX_WORD_LENGTH);
char* token = 0;
unsigned long wordCount = 0;
token = strtok(buffer, delimiters);
while (token != 0)
{
if (strlen(token) > 0)
{
++wordCount;
}
token = strtok(0, delimiters);
}
return (int)wordCount;
}

I'm not sure, but after following through the code, the code checks whether the word we are looking for is greater than length zero, hence always returning a value of at least 1.
What I was trying to do was to check for how many times $searchword appears within an array of an array of chars (simply put an array of strings) $sentences.

My apologies, the algorithm I posted will count the number of words in a character array. To find the number of times a substring appears in the array, you need to modify the algorithm to use strstr instead of strtok:
unsigned long HowManyWords(const char strWord[MAX_WORD_LENGTH], const char* substring)
{
char buffer[MAX_WORD_LENGTH] = {0};
memcpy(buffer, strWord, MAX_WORD_LENGTH);
char* token = 0;
unsigned long wordCount = 0;
token = strstr(buffer, substring);
while (token != 0 && *token != 0)
{
if (strlen(token) > 0)
{
++wordCount;
token += strlen(substring);
if (token >= buffer + MAX_WORD_LENGTH)
{
break;
}
}
token = strstr(token, substring);
}
return (int)wordCount;
}

Thanks.. I have updated the code accordingly, adding also a memcpy so that memcpy is used to copy the variables to local variables. I assume that this is a workaround for strstr (right?).
However, token seems to have a value of 0xcccccccc <Bad Ptr> when debugging, so the program never really checks.
Code:
int CSentenceAr::HowManyWords(const char strWord[MAX_WORD_LENGTH])
{
// initialize local variables
char strSearch[MAX_WORD_LENGTH] = {0};
memcpy(strSearch, strWord, MAX_WORD_LENGTH); //copies fixed array to strSearch
char* ptrToken = 0;
char strSentence[MAX_SENTENCE_LENGTH] = {0};
int iWordCount = 0;
for (int iCurrent = 0; iCurrent <= iNumberOfLines; iNumberOfLines++)
{
ptrToken = strstr(strSentence, strSearch);
while (ptrToken != 0 && *ptrToken != 0)
{ memcpy(strSentence, this->strSentence[iCurrent], MAX_SENTENCE_LENGTH);
if (strlen(ptrToken) > 0)
{ ++iWordCount;
ptrToken += strlen(strWord);
if (ptrToken >= strSentence + MAX_WORD_LENGTH)
{break;}
}
ptrToken = strstr(ptrToken, strSearch);
}
}
return (int) iWordCount;
}
