I have made a program using Microsoft Visual C++ 6.0 using MFC app, and ive decided to "enhance" it...
Its basically a "blog" or "journal" in a way... I was wondering whats the easiest way if someone clicks on "save" (i have it set to save to folder as (date).txt and inside is the entry... But i was thinking about using a Tree for the folder to easily access all journal entries... What would be the easiest way to access all the journal entries added using the same program?
Possibilities;
1) OnSave, saves file to folder and somehow automatically save title to a ComboBox that'll allow you to click on it and allow entry to be viewed...
2) Tree, having tree set to that folder only allowing user to click on file wanted and having it open entry like combobox idea...
Im queued... I dont know how to use the Tree control, all tutorials ive found are based around C:\\ (a tree for full harddrive with 2 classes and millions of files)... Is there a way to make it so that a user can view past save's in a combo box and being allowed to click on date to view entry?

Mentally separate the files (data) from your user interface considerations for a moment.
Suppose you had something like a calendar control instead, that had a different representation for the days that HAD journal entries. The user could go back and forth a month or year at a time. They could double-click on the day for the journal they wanted to see. Hovering over a date would show a tooltip with the subject of that journal. A sort of 'report view' in this control would perhaps have the date along the left column and the subject in the right column. Anyway, just a different way to think about selecting an entry than a 'tree view'.
If your data representation is separate from your user interface, you can experiment with different 'views' of your data without constantly rewriting your program.

Thanks... Never thought of it that way...
A friend of mine made a basic calander program for his class that would show white for non-entered data, and colored for entered data and when clicked it would open another CDialog with the data entry...
Similar to the idea of the ComboBox but i just started using MFC, and im just experimenting and ive caught onto it pretty easily... Thanks for your input ill give it a try...
Do you know any tutorials or open sources to easy access to files without trees that i could review?

There are some 'file helper classes' here on CodePRoject that fill CStringArray with all the files in a specified folder or set of folders. You might want to use them to find your journal entry files. The MFC class CFileFind performs local file searches. Also the FindFirstFile function searches a directory for a file or subdirectory whose name matches the specified name.

Hello, i hope that this question is not misplaced in this part of the Forum, but if it is then i apologies.
I have a Global Hook callback procedure that is executed by the system each time an application tries to install a hook. This procedure (DebugProc)takes the following standard parameters:
int nCode,WPARAM wParam,LPARAM lParam
where WPARAM contains the type hook that is trying to be installed.
LPARAM is a pointer to a DEBUGHOOKINFO structure (defined natively and not customely). Is it possible with those informations to get the process id that has initiated the installation of the hook?

See CreateToolhelp32Snapshot and specifically the TH32CS_SNAPTHREAD.
In the THREADENTRY32 you can correlate th32ThreadID (which you have) with th32OwnerProcessID (which you want to know). Assuming the tool help functions can work within the debug hook procedure.

Absolutely. The hook function is called from the context of the process and thread that performed the operation that caused the hook event to be triggered. This means that GetCurrentThreadID() and GetCurrentProcessID() will give you the thread and process IDs of the thread/process that caused the event.

Thank you for your quick answer. Unfortunately, the GetCurrentProcessId returns the process id of the application that installed the Debug Hook. The Debug Proc Callback procedure is triggered whenever an application (lets say for example a keylogger) tries to install a hook (like Keyboard Hook).
If i call GetCurrentProcessId() from the Debug Proc Callback, i get the process id of the my application (the one that installed the Debug Hook). What i need is to get the process id of the keylogger.

Hi
Would anyone have the source for the project at this address
http://www.codeproject.com/miscctrl/axtraycontrol.asp
Sounds similar to something I have been trying to do with PCR Plates. It doesn't seem to be posted any longer. I click on the download link and get page can't be found.
Thank you

Thanks to DavidCrow for suggesting to use onChar. I did it. Here how it is.
A small code is added to the wordpad sample of the VC++ to remap the keys.
If I type a I should get D and if I type b I should get e on the richedit document. It is working for the first case but not for the second case where unshift character is being sent with the SendMessage. How can I get that too.
void CWordPadView::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// TODO: Add your message handler code here and/or call default
switch(nChar)
{
case 'a':
SendMessage(WM_CHAR, 'D', 0);
break;
case 'b':
SendMessage(WM_CHAR, 'e', 0);
break;
}
}
In this it is working fine for case 'a' but it is not working for case 'b'. That is it is working for Capital letters A B C ... in SendMessage but not for small letters a b c .....
Can anyone help in making this work for unshift letters a b c...too. Thanks.

What happens if you remove the first case?
I've never done it this way, but what you have looks like recursion in the making. If you type an 'b' then a 'e' is sent to the view. At that point (I think) another WM_CHAR message is generated and the OnChar() method is called again. Yes? What happens in the switch() statement when an 'e' is encountered?
Another way to do this might be to actually replace the text in the rich edit control (as the special characters are typed) rather than sending WM_CHAR messages. Your way might work, but without actually testing it, I can't say for sure.

Sir
when I type 'a' then 'D' is appearing as I used D in the sendmessage
when I type 'b' then I am trying to send 'e', but it is typing only b.
when I type 'e' then I am sending 'I' capital I so it is typing I.
I mapped all the requirements for a thru z but, it is not working for all the cases where I am sending small letters but, it is working fine for all Capital Letters.
How can I do it for sending small letters too through sendmessage ? or is there any other method?
I am typing no special characters frequently, so how can I replace the text in the richedit control for every time I press alphabet keys or punctuation keys ?
Thanks a lot

Instead of using SendMessage(WM_CHAR, 'D', 0), using ReplaceSel("D"). This will prevent the recursion that David was talking about. This should work for lowercase and uppercase characters without a problem.

Thanks for great idea, but still it did not work for me. I am a novice and if you can give the piece of the code, the line of code, I'll try with it. It says error undeclared identifier ReplaceSel.
Thanks a lot.

Since you're using CRichEditView, you'll need to use GetRichEditCtrl().ReplaceSel(...)

Thanks for your response. I am still in trouble.
It is giving the following error if I try to implement it.
error C2664: 'ReplaceSel' : cannot convert parameter 1 from 'char [2]' to 'const unsigned short *'
void CWordPadView::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// TODO: Add your message handler code here and/or call default
switch(nChar)
{
case 'b':
GetRichEditCtrl().ReplaceSel("e") ;
break;
...
Can I get some solution ?

You didn't say you were compiling for Unicode Use _T("e") instead of just "e"

Thanks dear Ryan Binns! It worked with _T("e"). Thanks a lot .
Using same replacesel I am unable to put the characters above 128. Is there any way to do that ?
Thank you again.

Hi there
We've tried to write a screensaver that starts (a bit after it starts) and stops (after it stops) a service using the codeproject ServiceHelper class here: http://www.codeproject.com/system/cservicehelper.asp
the problem is that the screensaver runs fine when a user is logged in, but when they're logged out, there are no privileges granted to the process, so we get ERROR_ACCESS_DENIED from the call to the service control manager.
Can anyone help us think of a workaround?
|
|
|
|
|
Can we know, is your purpose to only start or stop this service if YOUR screensaver is running?
Or would you want this to happen for ANY screensaver?
Also, I just examined the source for the service helper class, and it asks for SERVICE_ALL_ACCESS just to start and stop a service. Why don't you try 'relaxing' the requirement to SERVICE_START for starting and SERVICE_STOP for stopping and see if that helps.
