Access code is VB code, just more limited. Visual Basic for Applications (VBA) is a subset of the full language. When coding Access apps quite a lot goes on 'behind the scenes' that you can't easily see. When manipulating a db with VB directly, you have to provide that functionality yourself. If I understand your question correctly, you are trying to populate a form with data that depends on a user selection from a combo box. You need to provide a function that intercepts the user selection event and executes a SELECT query on the database, then update the form controls with the resulting recordset.

Thanks a lot, Roger. I got the idea.

Can anyone point me to a class for creating an Application Task Bar in vb.net? I have a CS class, but it is incomplete and I am not having much luck repurposing it.
Either source code, or even a control that I can purchase that would allow me to dock a bar to the screen, hide it, etc.
Thanks;

Have a look at this:
John O'Byrne's
taskbarnotifier, a skinnable MSN Messenger-like popup in C# and now in VB.NET too

Not exactly what I am looking for, but a cool control.
I'm looking for a class that implements the Application Task Bar functionality of Docking and Hiding, etc that you get with typical XP-style toolbars on the Windows XP desktop.

I'm getting the following error in my app.
OutOfMemoryException' occurred in system.drawing.dll
On my Main window, I have a Listview, that has a images for the checkboxes, a outlook style bar down the side, and a picturebox that is displaying a animated gif file.
When I minimize my app to the System Tray (I also have a Notification Icon)
Me.ShowInTaskbar = False
When I go to pull it back up, I get this error, from the debugger. Now if I run the program outside of the debugger,after minimizing and restoring the form my images aren't where my checkboxes were.
Now something else I tried, was just having my program minimize to the taskbar. There was no problem at all. My images on the listview are in place of the checkboxes.
I know of course it has something to do with the drawing related stuff, but I'd like to avoid this error, and keep my images on the listview. Dave you have any suggestions..
Thanks in advance.

WIthout seeing any drawing code, it's hard to tell you what's going on. But, if your drawing anything yourself, make SURE your .Dispose() any Graphics objects and release any handles you're getting from Win32 API, using the Win32 API.

The Thing is I'm not doing any drawing stuff my self. I've just got a picture box, a listview with images for the checkboxes, and a outlook side bar. I did some more playing around with it last night, When I minimize my form, i have 2 options for the user, to have it minimize to the system tray, or minimize to taskbar. If I have my progam minimize to the system tray, then restore the form,
Me.ShowInTaskbar = True
Then My images on my listview are no longer there, and all I've got is checkboxes.
Minimizing to taskbar, does everything just fine. I'm not understanding what I'm doing wrong
Thanks again for your help

Are your images store in an ImageList? Try to avoid it if you can.

That's how I have my images, in a image list. I can avoid it if I can set the images at runtime, for when it's checked or not checked. You don't have a brief example on how to just set the image for a item in a listview - I have it on details view and checkboxes enabled.
Thanks for your help

Please any body who might give an opinion about my Save Data ..!
MsgBox("Is Data Correctly Right ?", MsgBoxStyle.YesNo, "Confirmation")<br />
If MsgBoxResult.Yes Then<br />
drcustoms = dtcustoms.NewRow<br />
drcustoms("cstcd") = txtcstcd.text<br />
drcustoms("cstnm") = txtcstnm.text<br />
drcustoms("cstadrs") = txtcstadrs.text<br />
drcustoms("cstphno") = txtcstphno.text<br />
conn.Open<br />
endif<br />
the procedure is after the message box appear and the answer is "Yes" the field should save in the database, if the answer is "No" abort the save.
I'am the new bies and interesting in VB.NET programming. Please give an opnion
if any body know the right and the simple code program.
Best Regards,

Without seeing the rest of your code, like what's drcustoms, dtcustoms, and what the rest of that conn object looks like, it's very difficult to tell you what your doing wrong.
I can tell your that you set the values of a bunch of fields, then opened a connection to a database, but you DIDN'T execute any proecure to write that information to the database, nor did you close the connection to it.

First of all, try something like "Is the data correct?".
secondly, you will need to add
drcustoms("cstphno") = txtcstphno.text
--> dtcustoms.rows.add(drcustoms)
finally, this will just be storing the data in a disconnected datatable. To send the data back to the database, you will need to
a)create a database command,
build a sql string (or preferably use a stored procedure)
execute the command
or b) use the Update method of a dataAdapter

im very confused on how and if you can make a app compatible with different OS
thanks,

What do you mean? An app that works on both Windows (.NET Framework) and Linux (Mono)?
The .NET Framework only works on Windows. It is Microsoft's implementation of the ECMA-335 standard, otherwise known as the Common Language Infrastructure. It describes a language independent runtime engine and a basic set of universal classes and uniform functionality that work under all implementations of the framework.

so basicly no matter what OS(win95,98,me,2k, ect...) as long as u have the .net framework installed you can run any app right?
and also i posted this under the .net framework forum
is there a smaller version of the .net framework redistributable,
the one i saw was 23698 KB, witch is no big deal for someone with high speed internet, but a bare of a DL for a 56k user just to run a app in the framework..

Windows 95 isn't supported, so don't even bother.
Windows 98 is supported, but should really upgrade to XP Pro anyway.
Windows 2000 and XP is fully supported, but still requires that download.
Windows Server 2003 comes with the .NET Framework 1.1 already installed.
Windows Longhorn will have the .NET Framework as an integral part os the O/S.
There is no smaller version of the .NET Framework, you have to install the full version. The .NET Compact Framework is for Pocket PC's and Windows CE machines only.
There are people trying to package their apps with a stripped down, essentials only "version" of the framework. This means that only parts of the framework that are essential to running the app are "installed". This is not supported by Microsoft and noone really knows what the implications are to a future installation of the full framework and what implications are for the installation of service packs for a partial installation of the .NET Framework.

thanks for the info, from what i understand if you install .net framework 1.0
and wanted 1.1 you have to uninstall 1.0 before installing 1.1. If i read that right on the microsoft site so i would say installing parts could cause prob's, but i could be wrong about this.

No, you can run both frameworks side-by-side. You can install 1.0 and 1.1 and 2.0 (when it comes out) without any problems.

Good afternoon...
Currently, we are using MDI(multiple document interface) in VB.Net. We have a parent form named frmMain and it has a main menu. Under the parent form's main menu, it has the following menu items like Data, Figures, Tools, Help, etc... Each of the children's forms have also a main menu under them. But when we run the application and open a child form, the child form's menu items appear in the parent form and no longer at the child's form. How can I make the children's menu items appear in their forms? Are there limitations in MDI? What are they? Can you give an advice?
Thank you in advance....

Using the MDI model built into Windows Form, you can't.

First, don't send a message directly to me or anyone else for that matter, and then post the same message on the board, it's confusing and people can't see the thread that's going on.
Controlling another computer from your is going to be very difficult. Even more so if your not using VC++ to do it.
You'll need to write two programs, a client that is running on the client computer and will provide the interface so you can control the client computer and do the monitoring that you want. The client should report back to the server with any changes in status, like the computer being logged off or being shutdown. The second app will be the server app that collects the status information from the client and provides the user interface to control the client machine.
Figure it will take approximately 6 months of development time times what you get paid per month. Is this number greater than the cost of PCAnywhere, which does exactly what you want to do?
