exit Visual Studio, delete the projects *.clw file then start Visual Studio again. The Class Wizard file (*.clw) will be regenerated and all references to the ActiveX control should be gone.

Answer to your question is:
http://www.codeproject.com/script/comments/forums.asp?forumid=1647&df=3&app=25&tid=25406&select=25406#xx25492xx
By the way, do you know how to change the MSysObjects attributes to read only thru VC?
I will be able to read tables info if I could do that. By default, MSysObjects cannot be read. I can change the setting thru Access 2000 but I want to do it thru VC!

What if you use SQL CREATE TABLE statemnt or even better the SQL Stored Procedures in your VC++ along with DAO, instead of the DAO lonely & directly?

I have noticed an anoying bug in my context menu. Here it is:
I have a SDI App, with the base view class of CTreeView. I have split the frame in two views - Left is Tree, right is the ListView.
When i insert the following code in to the OnContextMenu function
CMenu menu;
menu.LoadMenu(IDR_MAIN);
CMenu pContext = menu.GetSubMenu(0);
pContext->TrackPopupMenu(this->m_hWnd, TPM_LEFTBUTTON|TPM_LEFTALIGN|TPM_RIGHTBUTTON,
point.x, point.y, AfxGetMainWnd());
(I'm not sure if the parameters are in the same order - if they are not - ignore it, in the code they are correct)
The first time I right click it shows the popup menu which contains 2 functions, and also adds some elements from the help menu?! The second time i rclick it shows it as it should be. But if I display the context menu associated with the caption (Restore/Minimize/Close etc.) it makes the same stupid mistake.
What am I doing wrong?!
Any help appreciated,
Deian

Continuing with my theme of building useless applications to utilise controls and programming practices to get a fuller understanding of the whole VC++ thing, I have come up with the following idea, but no way to implement it.
Wanted to add some data to my application via a String Table (don't want to use the Registry or write to hidden files) for use in calculations. Also wanted to enable the user to be able to re-map this data to new values that would be available next time the application was started. Seems that according to MSDN I can't write data to String Tables and can't find anything in books, magazines or web sites to help me along.
Anyone have any idea how I can get this idea to work?
Must be possible as Shareware applications (no I am not writing one or trying to hack one) must store the registration key somewhere for the app to know it is registered. Or at least write something to the executable to show it is registered. Don't believe that it would be written to the Registry or a hidden file as this would be comparitively easy to find.

Do you think ? Writing to the executable or a file in the local directory would be easy. Writing a nonsensical ( or at least obsfucated ) value to an obscure part of the registry would be far harder to find. How about creating a file with an unusual name in the Windows system directory and storing info there ? I have shareware programs that I am *sure* write to my boot sector as they still know I have expired my trial after a reformat of the HDD !! ( I own them and get the message after reinstall prior to entering my key ).
I guess all of these methods are kind of user hostile, but I'm sure they are harder to find than modifying the actual executable - surely the first place a hacker wsould look.

hi,
Yupe,... string table is a resource and is read-only. I dont think its possible (to my knowledge) to alter it afterwards.
Thats the reason people go for registry or flatfiles. Actually there is no harm in writing to registry if its not too much data. There are lots of apps. which write to registry extensively .. eg. (www.groove.net).
Shareware programs. have the algorithm inside for generating the appropriate key. You give the username and reg.code, now the program has a key generator inside and hence it generates the corresponding reg.code for this user and compares it with the one you have entered and hence it can recoginize them. Some, shareware store the password info in an encrypted form(using techniques like md5 message digest) and store them in the registry.

Hi, there.
I made a simple dialog-based app, I indend to add a CScrollView in that dialog, so that I can draw digrams in the View which is scrollable.
I searched solution for this case in books without success.
Could you please advise me?
Thanks a lot,

Hello, the codegurus around the world.;)
Technically, this is possible since Paul Dilascia in MSDN Magazine posted the code
to show CHtmlView on the dialog based application about one year ago?
However, I forgot the back number, but try to find the article in MSDN home page.
http://msdn.microsoft.com/msdnmag
Also, I have read the article that someone succeeded in showing CView
on the dialog at the newsgroup of Microsoft.
Good luck.

How to make a new DSN during the instalation with InstallShield.
|
|
|
|
|
One method(and you didn't here it from me) is to create the appropriate registry entries under the HKLM(for System DSN) or HKCU(for User DSN) \Software\ODBC... look at existing registry keys for the appropriate values to use for your DSN. This isn't recommended because the registry may change and your install won't know it...
I'm not very familiar with Install Shield, but I do know that they allow you to create scripts that can call functions in dll's...
Try your hand at using the following ODBC API functions from your install shield script:
BOOL SQLConfigDataSource(
HWND hwndParent,
WORD fRequest,
LPCSTR lpszDriver,
LPCSTR lpszAttributes);
This function declaration and some of the #defines you'll need are in odbcinst.h. I can't remember which odbc dll it resides in, but I'm pretty sure it's on any machine that uses odbc.
This function will create an ODBC datasource, but it's behavior seems to vary from database to database, ie: if there's not enough data in your lpszAttributes parameter, a dialog may show prompting for the rest of the data, or the function may fail... depends on your database software...
Sample use(from docs):
SQL_RETCODE rc;
UCHAR *szDriver = "SQL Server";
UCHAR *szAttributes =
"DSN=MyDSN\0DESCRIPTION=SQLConfigDSN Sample\0"
"SERVER=MySQL\0ADDRESS=MyServer\0NETWORK=dbmssocn\0"
"DATABASE=pubs\0";
rc = SQLConfigDataSource(NULL, ODBC_ADD_DSN, szDriver, szAttributes);
-Good luck!

Hi,
I need to implement an ActiveX control text editor that draws a line at the end of each paragraph. I guess my two alternatives are either to start from scratch, or subclass something like the RichEdit control. I've had a look through various articles on subclassing but I haven't found anything that would give me a clue as to where to start for this kind of thing. Can anyone suggest something that I might take a look at to get started, or is this really a case of writing the whole thing from the ground up?
Thanks,
Richard.

hi,
For storing the screen(client area) content as bitmap,there is a article in MSDN under ...

Hope this helps
