All my cases (Systray Clock, TaskBar, Systray Window) are CallWindowProc with the handle returned when I subclassed via SetWindowLong....
Hm, as far as I see the hook isn't even as good as I thought. It has a few minor problems. But if I have no choice I'll keep it. I think I will soon try that HTCLIENT thingy that you mentioned. But right now I can't 'cause I gotta release on my head and just a few more hours to deliver it. (it's the second Beta of the freeware application I'm working on and I'm giving it to some more friends to use and report bugs ::- D ).

We just moved to Visual Studio 2005, and previously we were using a manifest file to make our vc6 apps look ala Windows Xp theme.
1. First of all, what the heck is this manifest file? Does it really do anything useful?
2. What is the correct way to use it for apps created in vc2005?
3. Is there any way to get menus to look half decent without integrating one of the xp-style menu implementations found here in CodeProject?
Cheers and thanks!

1 - as well as turning themes on, it specifies which versions of dlls your app uses.
2 - in your linker properties, you can get a manifest auto generated and embedded in your app
3 - Themes don't really do much for menus, they certainly don't add stuff like icons, which you could get from a library like Ultimate Toolbox, or possibly from samples on CP.

Christian, have any links for dealing with distrusting apps created in VS2005? Something like "Here dummy, it takes two minutes to set your app up for distribution"?
Any help is apprecated.
Thank You

Ok so i have my manifest file being generated to "$(IntDir)\$(TargetFileName).intermediate.manifest". How do I enable the themes? I imported this project from vc6, so it doesn't have it on by default.
Thanks

It will repaint the window. If you want to erase the current shape, you need to change ShapeKind first.

If I high-light some text in a window and right-click the mouse, there will be a popup menu with items like copy, cut, paste, etc.
If I know the handle of the window, how to get the handle of the popup menu? I know about the GetMenu API, does it do what I want?
This is for a non-MFC app. Please note that I don't want to create a new menu, just needs the handle of the existing popup menu.
Thanks.

Generally, the menu is created just before it is used and destroyed afterwards (most developers would do it this way), so you can't get a handle to it. Even if it was kept around, there is no API to get its handle because it is not a Windows function - the application takes care of creating and storing it, and just calls TrackPopupMenu() when necessary to display it.

What I want to do is adding some items to the menu, not replacing the menu. The application is not mine, I need to install a hook to get into the application. Currently I am trying other ways.
Thanks.

Then you might subclass the window and handle the WM_INITMENUPOPUP and, maybe, WM_RBUTTONUP messages.

How can I convert the standard MRU file list in menu File
to a popup submenu in menu File in a MDI application ?
Manosza.

Hi,
I want to add a password at a document level. I have an MDI app. My idea is to add a password variable, allow the user to create a password and archive it during serialization. Then, whenever the user opens that file, during the onopendocument process, I want to open a modal dialog box, get a password from the user, check it against the one that was saved during serialization and then decide to open the document or not. I tried doing domodal on a dialog box during serialization and during the onopendocument functions in CDocument, but neither would work, it kept throwing exceptions. Also, once I get the password and check it against the saved one, how can I abort the opening of the document? Any ideas on how I can do this? Thanks.

do all of this work before actually loading the file; you can do a lot of things before calling serialization.
you first do a "pre-read" (hidden from the user ) to see if the document is protected, then if it's not protected, you load it, if it's protected, read the password, compare it with the one in the document, if password is ok, read the file.
or simply ask for the password, then call the serialization and check there if the password is valid, and exit from the serialization.

Great, thanks for the ideas. I realized that I have some code in my main app's file that opens the last open document. It seems this is causing the problem. I'll try to work it out. Thanks for the help.

Hi Arnold,
checkout the LockNote[^] project at SourceForge. It's open-source and it does exactly what you want to do. So dig into the sources and you'll surely find many answers for your problems.

Is it possible using plain C to compact and repair a MS Access Database trough ODBC?
I'm trying the following code, found it in the WEB:
void CompactAndRepairDB ()<br />
{<br />
RETCODE retcode;<br />
int subscrp;<br />
<br />
CHAR szDriver[] = "Microsoft Access Driver (*.mdb)";<br />
CHAR *szAttributes2[] =<br />
{"REPAIR_DB=db.mdb\0\0",<br />
<br />
"COMPACT_DB=db.mdb db2.mdb General\0\0"};<br />
<br />
for (subscrp = 0; subscrp <= ((sizeof szAttributes2 / sizeof(UCHAR *)) - 1); subscrp++)<br />
{<br />
retcode = SQLConfigDataSource (NULL, ODBC_ADD_DSN, szDriver, szAttributes2[subscrp]);<br />
if (retcode != TRUE)<br />
{<br />
for(int i=1;i<=8;i++)<br />
{<br />
DWORD dwcode = NULL;<br />
WORD wlen = 0;<br />
char szerr[SQL_MAX_MESSAGE_LENGTH] = {0};<br />
if (SQLInstallerError((WORD)i, &dwcode, szerr, SQL_MAX_MESSAGE_LENGTH-1, &wlen) == SQL_SUCCESS)<br />
printf ("Code: %u %s\n",dwcode,szerr);<br />
}<br />
}<br />
}<br />
}
After creating the new compacted file I copy it over the old file.
Though when I run the compacting program I get the following error:
Driver's ConfigDSN, ConfigDriver, or ConfigTranslator failed.
I'm not using an ODBC datasource, only using filenames.
Thanks in advance,
Anfernius

Hi guys,
I hope I do not have overlooked something small in my code, or you probably will make fun of me:
I have a function that determines if a critical error has occured in really old code which just returns a list of structs containing error information. Someone already added a std::string containing the error-message to these structs, and I can simply get that one.
I need to ignore a certain error message (which virtually always occurs), so I wrote the following code:
<br />
std::string noRecords = "no records found";
for (int i = curr.numberOfElements(); i > 0; --i) <br />
{<br />
if (std::string::npos != curr.currentElement.info.find_first_of(noRecords))<br />
{<br />
return true;<br />
}<br />
curr.setToPreviousElement();<br />
}<br />
return false;<br />
<br />
which is supposed to return true ("a real error occured") if there is any other error than "no records found" and false otherwise (i.e. "just noRecords errors").
As mentioned before, I cannot change the implementation of the errorList. Just ignore the naming, please, as I had to "obfuscate" a little.
Well, the result: obviously "no records found" is a part of "unexpected end of file". Thats what currElement.info (the std::string) contains.
I also tried the following comparisons:
curr.currentElement.info.find_first_of(noRecords) < 0
curr.currentElement.info.find_first_of("no records found") < 0
curr.currentElement.info.find_first_of("no records found") != std::string::npos
but to no avail. I tried over 100 info strings with the above function, it never got inside the conditional.
I HOPE that this is really simple (that means, I messed up somewhere). find_first_of actually IS the string::find_first_of(), I double-checked that.
GNAH.
Cheers,
Sebastian

First of all, this is the wrong approach. You should fix the bug, not hide it.
find_first_of will find the first char in your string which is one of the chars in the string you passed in. I think you want string::find.

First of all, I know, but there is nothing I can do about it.
And, BUMMER, I totally misunderstood the MSDN. Another problem if you're not a native speaker and just "taking a glance" at the docs.
Of course, find() is what I have to use.
Thank you very much, Christian.
Cheers,
Sebastian

I understand that the equivalent for __gc in VC++ 2005 is ref keyword. Similarly can anyone update me on the equivalent for __gc* in VC++ 2005.
Thanks in advance
