I am working on an app that is an MDI. When the user clicks a button on an MDI child, I want to "disable" the current MDI child (and only the current child window), open a new window that has control, and then re-enable the child window when the new window is closed...very similar to using showDialog(). The thing I an having trouble figuring out is how to allow the other child windows to be active at the same time as when the new window is open. If I use the showDialog(), all child windows are disabled

I am using vb.net 2003 and an Access database connected via Jet 4.0 OleDb. I have identified the location of my database using a relative path with [code]My program was working fine and I began making some cosmetic changes.I thought it would be a nice touch to add a PictureBox on the first form and allow the user to select the image that he would like to see when running the program.I added a menu item to "change the picture" and on a form added an OpenFile Dialog. I added code to capture the location of the selected file and used it to identify the image to be shown.I included a table in my database to store the file name and path which is loaded when the program starts.This all worked fine. I could change from picture to picture and the image would be updated each time in the picture box and in the database. I could access the database and perform all of the functions of the program.
That is as long as the image files that I selected were located in program startup directory. If I selected an image with the openfile dialog which was located else where then I could no longer contect to the database. I receive an "unhandled exceptions error". Below is the openfle code:[code]Can anyone help me with the proper way to get set up the open file dialog so that the results do not conflict with my database connection, or re-establish the connection?[code]
I am using vb.net 2003. In my program, the user can use an openfile dialog box to locate the address of a image and use it to change the display. The name and path of the image is saved in a database. This image is then loaded upon startup. If the image is located in the start-up directory the image change and saving to the database works great. But if the image is located some where else the image change occurs, but the path of the database has changed to the location of the image. Since the database is not located there, I get an unhandle exception error. What is the code to redirect the program to my startup path?
View 5 RepliesHow to change the database connection by using openfiledilog in windows forms? The application I need to do, need to connect to a database, each time with different path and different name to explore the opened database. All the databases to be accessed are having the same structure, but with different location (in the pc itself), different name, and with different data inside (but the database tables and relations are the same. I understand openfiledialog.filename contains the address for the clicked file, but failed to pass this information to update the Database conection with the new addrerss.

So the code below is called when a user selects Save on an ExtJS popup modal window. This window ONLY contains a combobox. Now, sometimes when a user saves this, and then re-opens it later on, the combobox will appear BEHIND the window all grayed out, unable to get to. Other times, it will be fine and work, and no difference in events happening either time, just complete utter inconsistency.

I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):

View 4 RepliesI deal with a lot of com class code. So, my code generally doesn't have a UI.I can't count on the calling code UI to handle the progress nor would they know the progress of my routines. I'm used to a language that allows you to call a progress window from any code. I've been banging my head up against a wall trying to find a way to create a simple Custom Control that I can simply call from my code that opens a modal window to report the progress.No matter what, I see a need for the backgroundworker in my code. But if the backgroundworker is declared in my code, I can't expose the doWork in the doworker sub.

If I type this code (VB.net 2003):
Dim myDialog As frmTestDialog
myDialog = New frmTestDialog
myDialog.Show()
you'd expect some dialog window to appear in a non-modal state. For some reason, this isn't the case with a program I am working on. Most of the dialogs use ShowDialog() to open them, and one uses Show(). The second I try to show another non-modal dialog, the dialog appears in a modal state. Another strange thing is, before I show the dialog, there is code to shift the dialog location to centre it on the main form - this isn't executed either: the dialog appears at 0,0.
My usual trend is to blame myself for errors (usually the case), then I blame the software; I have checked every single line of code (including the generated code), and it all checks out - the dialog should be non-modal. But ... it's not. I've come across other errors in VB.net 2003; is this another instance?
I'll try creating a new dialog and displaying this non-modal, and see what happens. If it works, I can just transplant the code but this shouldn't be happening, just like if I go to a shop, ask for a cola, I expect a cola not a Chinese panda; more annoying, I return the panda, ask for a cola, and they give me the panda back do loop until I give up The system does using threading, but none of that code connects to the display dialog routines all dialogs are opened with more-or-less the above code (a few have simple validation routines).
I am trying to show a message box when an error occurs in a modal dialog window but for some reason the message box is never shown although I know the MessageBox.Show method is being hit. The try catch block is inside of an event handler for a windows form that is being shown as a modal dialog. I know that the event is being fired and that the error is being caught but the message box never opens. I've replaced the MessageBox.Show with another form show and it works fine but I'd rather use MessageBox instead of creating my own error form. I just can't seem to make MessageBox work. Is this a limitation of MessageBox? Here is a simplified version of what I am doing:
