i have written an editor in vb.net. now i want to put the functionality of 'save' and 'save as'. the functionality must b in such a way that if a user has once saved the data, he may not b asked for the path of the file to be stored. can some one tell me how can i do that?
regards

Just save the file path in a variable and when you click your Save button, have it read the whether or not the file path is set. Like so:
If FilePath <> "" Then
SaveFunction(FilePath)
Else
SaveAs()
End If
Hope this helps you out.

how to set an image size as the screen resolution size?
Happy Holidays

What? Are you asking how to change the magnification of the image? You would normally just use one of the DrawImage overloads that let you specify the size of the drawn image. It'll be scaled automatically to that size on the target drawing surface.

You're still not.

So, what's stopping you from drawing the image, or whatever your app is doing, using one of the DrawImage overloads?
You have to spell out what your app is doing and how this image is being displayed. Is it in a PictureBox? Is it the background image of a control or form? ...?

Hi there,
Is there a way to update a certain dll's components in a ComPlus application via InstallShield or VB code?
Any help or hint on this will be appreciated.

If I understand the question, no you can't edit the .DLL. You have to change the code, compile it, then replace the .DLL file with the new one.
With InstallShield, you can make a patch installation that will make the necessary changes to the .DLL file, but it needs the original .DLL file and the new one to build the edit patch because the edit will only work on the version of the .DLL file.
It's a heck of a lot easier to just unregister and replace the old .DLL file with the new one and re-register.

Hi,
Right-clicking on a file and selecting Properties will always change
the access date, because Explorer is accessing the file to retrieve
several items of information. In Explorer, you can add "Date Accessed"
to be displayed in the "Details" view to see the "real" access date.
Also, using cmd.exe's "dir /TA" or the VBScript below shows me
different (real) access dates, so I would think it is the File class
in .Net that have the problem. I suggest you post in some of the .Net
developer newsgroups.
'--------------------8<----------------------
Set oShell = CreateObject("WScript.Shell")
Set oFSO = CreateObject("Scripting.FileSystemObject")
sDesktopPath = oShell.SpecialFolders("Desktop")
Set oFolder = oFSO.GetFolder(sDesktopPath)
For Each oFile In oFolder.Files
sFileInfo = sFileInfo & oFile.DateLastAccessed & ", " & oFile.Name & vbCrLf
Next
WScript.Echo sFileInfo
'--------------------8<----------------------

The LastAccess date in the last time the file was read/written to. If you get Properties on a file in Explorer, the file is opened and read to fill in some of the informaiton in the Properties dialog box, like the Version of Summary tabs. This is something that we all know about. Just about noone ever uses the LastAccessed date/time either because it's too easy to change it. The LastModified date/time is far more commonly used.
You're not telling anyone anything we didn't already know. Besides, posting something like this in the forums is pointless because it'll just drop out of sight in the next week and noone ever searches the forums before they post a question anyway.

Ya..
Actually i wanted to know when the File is last opened or executed.
The requrement is like that.
I want to trace the date and time of my software's last run.
Just Understand that..This is to track the events going on in our client place.
I know that what u are telling is making the sense.
But you must know what i want..
Thanx 4 ur reply..
Any suggestions from you??

Your applicaiton should log this somewhere. Depending on the security requirements, you could even log this to an encrypted XML file hidden somewhere or to the systems own event log. But, depending on the LastAccess time is not reliable at all, considering you can screw it up just by getting properties on it or if backup software runs and backs it up to tape or something.

You put the BeginTransaction at the start of your queries. If you have an error then use RollbackTransaction to undo the changes you've made on the database. If everything works then put CommitTransaction at the end and close the connection.
A note of caution: While a transaction is in progress parts of the database will get locked out from other processes that are trying to access it. This is to ensure the safety of the transaction and other processes that are accessing the database. When you start a transaction perform the queries you need quickly so that the locks don't last long. And do not wait for user input inside a transaction.

Hello to all, I am a newbie with the visual basic language and i am currently building a small application for my company to edit a specific part of a database. I am using the ado data control for this and i have everything functioning expect for my delete button, thing is it works but it only deletes one record from the field whereas i would like it to delete all the records in the field that match the data in a text box that data is entered into by the user. Please any help would be appreciated, i've been fighting for weeks with this. I even tried using sql queries and they fail me as well, cause my delete command doesn't seem to work. Feel free to ask questions if i haven't made my self clear enough. Thank you.

What is the SQL query you are using?
