I'm somewhat ashamed that I didn't saw the MFC setting, but the keyboard problem remains unsolved.
If I set keyboard mapping to VC6, F4 maps to View.NextTask. In .NET, only build messages are considered as a "task". I want to be able to use a keyboard shortcut to step forward in for example the find output or output from an external tool such as LINT.

Modify F4 to point to "Edit.GotoNextLocation"

hi guys,
i am using a derived class from the CDaoRecordset ( Table-type )class for my database. I tryed the following code and i got an assert. The assert is in the requery() function. I cant use the Requery() function i dont know why !!!
Please see code:
in my function
m_pSet = new CDaoTable;
m_pSet->Open();
m_pSet->AddNew();
m_pSet->m_Auto = "XXX";
m_pSet->Update();
m_pSet->m_strFilter = "Auto='XXX'";
// here i got the assert
m_pSet->Requery();
...
The assert is in the daocore.cpp line 3611 "ASSERT(CanRestart());
Best Regards
Sonu

I think it's because of your cursel type I don't remember now which one couldn't use Requery(),but you can check in MSDN

Hi,
I have inserted an ActiveX control in an automated session of Word in my App, but now I´m trying to get the dispatch pointer and it doesn´t work, I made:
Word::InlineShapePtr pShp = m_pWord->GetSelection()->InlineShapes->AddOLEObject(vClassType);
Word::OLEFormatPtr pFmt = pShp->OLEFormat;
IDispatch *pDispatch = pFmt->Object;
TRACE(pFmt->ClassType);
IGDIGraphics Control(pDispatch);
COleVariant x((long) 10, VT_I4);
COleVariant y((long) 10, VT_I4);
COleVariant title(TEXT("Method called from the App"));
Control.DrTextSimple(x, y, title);
(*) The IGDIGraphics is a wrapper class created by the Wizard of MFC...
The when I try to execute the method the program crashes, what I have made wrong ?, Thanks in advance

Hola Braulio,
Maybe this totally misses the shot, but something caught my eye. I guess IGDIGraphics encapsulates a pointer to some COM interface called the same. If so, why are you providing a IDispatch * to the ctor of Control? Shouldn't you obtain the proper pointer from pDispatch through QueryInterface? Just a guess...

Hola Joaquin !
MMmm..., I think "pFmt->Object" returns and IDispatch, in theory the constructor of the wrapper class would accept that dispatch and then I could use that sugar class, but... 
How could I do it in the hard way ( without wrapper classes), I would like to get the interface and then call "invoke" or get my interface, but I´m not used to COM and MFC
Thanks for your help, Bye !

You can verify this by looking into the code for the wrapper. Some call to QueryInterface should be done inside to retrieve a proper pointer from the IDispatch *.
Also, assuming that the wrapper actually does the QueryInterface thing, can you verify that the pointer obtained is not null? Maybe what you're passing does not implement IGDIGraphic after all.

For doing that you must obtain first the GUID for the interface. With this piece of info, the rest is simple following the documentation on QueryInterface (call pFmt->Object->QueryInterface(...)).

Hola !
Finally the problem was using the class generated by the MFC wizard, I change to smart pointers, and it worked perfect ( and Smart pointers are pretty cool as well, it looks like VBasic code !).
Thanks Joaquin !, Bye !

Can you you have more than one "throw" statements with the same parameters for a single try, throw catch execution.
Ex.
try {
Function()
}
catch ( CString s ) {
AfxMessageBox(s);
return FALSE;
}
Function() {
//some coding
if() {
CString dum = Error in this file;
throw dum;
}
//some more code
if () {
CString mud = SUCCESS;
throw SUCCESS;
}
}

Yes you can. From the point of view of the local flow within the function, each throw behaves as a return.

Just an FYI. Throws should never be used as part of normal program flow. The overhead is massive.
Exceptions (i.e. throws) should only be used for that, exceptions to normal program flow.

ShowWindow (hWnd, SW_MINIMIZE) doesn't work in this case and
neither does WM_SYSCOMMAND with wParam = SC_MINIMIZE.
There's no counterpart to WM_MDIMAXIMIZE and I want all the child windows minimized by one command in the menu. Any idea?
|

|

Iterate truough the children window of the frame with EnumChildWindows and call CWnd::ShowWindow(SW_MINIMIZE) on each of them.

Windows weren't minimized in MDI fashion, that is as small bars with icon, text, close and minimize, maximize buttons.
Instead it was only one small bar in the lower left corner of MDI frame window - for all childs !

Yep, I've reproduced the behavior you describe. Try putting the command handler in your CMainFrame and passing m_hWndMDIClient as the hwnd parameter or EnumChildWindows (I've just done it and it works, though a little slowly).

I am new to all this and have made a text editor ( one of the most easy things
to start with ) but i want it to save an encrypted file that no other text
editor could read, so when you click save it asks for a password the saves
the encrypted text then when someone tries to load it they have to enter
the password??
Thanks in advance Steven Richardson!
P.S. i have Borland C++ Builder 5

How long is a piece of string? A really easy way to do it is just to take the raw text and XOR each byte with a constant byte value. That turns the text into garbage. Then you check the password. If it matches you XOR each byte of the garbage with the same constant byte and voila your original text is back.
Example:
Encryption - 101 xor 011 = 110
Decryption - 110 xor 011 = 101
This is really insecure but it's dead easy. It depends on what level of security you need. If you're just looking for something to stop casual observers then this will do the trick but if you expect someone to expend some effort in cracking your encrypted text and it's security is important then you need to look for something more significant than this.
There are plenty of industrial strength algorithms about but I'm no expert on current practices. Just google for 'encryption' for details.
The other potential problem with what you propose is that your security model is trivially broken if the password is revealed. Look for 'public key encryption' to avoid this.

Hi, I have following technical question. Maybe someone has the knowhow, so I wouldm´t have to worry about seeking further
I have a server, he receives from somewhare a port number. So I want to find out what process communicates wia this port.
More rigurous:
I would like to find a method about determining a Process ID knowing a port number of a connection opened by this process.
Any hint would be highly appreciated.
Thanx

I don't know how it's done but Foundstone have a free tool called FPort (in the Intrusion Detection section) that will do it for you. As far as I'm concerned actually doing this is deep voodoo.

I am trying to print an area of the screen (specifically the VIEW only). I have a Dialog bar on top. When I do a GetClient rect, I get the size of the VIEW. This is fine. However, I grab the DC of the screen which includes the bar. The screen coordinates has the right width and height dimensions but not the offset to take into account the bar which I don,t want. From my view how would I get the dimensions of the View RELATIVE to the entire screen? Any other way? I am putting this in a derived view which ALL my views derive from. Thus, I really do not want to make this specific for this app but instead a general solution without knowing if there is none, one or ... Dialog bars on top.
Thanks in advance.

Hi Stan, maybe <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmfc98/html/_mfc_cwnd.3a3a.clienttoscreen.asp">CWnd::ClientToScreen</a> is the function you're looking for.
