With .Net 3.5 / VB 2008 / WinXP...I'm using a Listview control in Details view. Two columns with an image on the left and text on the right. FullRowSelect is set to true. All works fine except that in the selected item the image is not visible. It's replaced by a white background. I need the image to be visible within the selected ListViewItem's blue background. Do I need to switch to OwnerDraw or is there another way to keep the image visible?

A particular VB.NET project is actually throwing 'Build Failed' But when I try rebuilding again it says 'Rebuild Succeeded'. It keeps alternating this behavior. Kind of random. Any vbc.exe issue of long locking the PDB or xml files?
View 9 RepliesI have a vb.net 2008 windows form application that I was just assigned to work on. how to maintain and test changes to both the pre build and the post build events? Can you tell me how to test these events? My postbuild event, I believe calls a project file in the solution file that wraps files together in a bundle in debug mode. Can you tell me how the posbuild event works and when it is called?
View 2 RepliesI am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?

I can't understand what I am doing wrong ... I have a form on which there is a label . This label is actually part of a control array of labels (it was created by the migration wizard trough the upgrading process) . Each time I run the program and call my form , a message appears saying :Control array element 12 doesn't existAnd this is what I don't understand .I can see it during design time , how come it disappears during run time ? I have even checked its Index property , it's 12
View 3 RepliesI have a vb.net 2005 windows form with a menu strip that keeps disappearing both in design mode and when the program runs. I noticed that on other forms there are more properties listed for the menu than this one has. Anybody familiar with this problem?

I have a panel on my GUI with radio buttons. When I run the code to determine which is the checked radio button from that panel, the code runs fine, but the panel disappears from the GUI after that. Here is the code I have to determine the checked radio button:
Dim rbName = (From r As RadioButton In Panel1.Controls.OfType(Of RadioButton)() Where r.Checked Select r.Name)
System.Console.WriteLine(rbName.First)
I have tried using:
Panel1.Visible = True
and also
Panel1.Show()
Panel1.Refresh()
but it doesn't show the panel again. I tried the same thing for individual radio buttons such as RadioButton1.Visible = True and it doesn't work.
I have a bound datagridview and a dataset with tables.
I have two sets of comboboxes bound to the same field "Restaurant" in the tables (mirroring each other).
In the "NewEmployeeRestaurant" combobox I change the value and it reflects in the datagridview. I can shoot around clicking all over the datagridview on other employees, but when I return to the employee I changed, the value remains what I changed it to. All is good in the world.
However, when I go to the "EmployeeRestaurant" combobox with the same settings, I change the value and it is reflected in the datagridview. So far so good. But when I go to another employee then click back on that employee I changed, the datagridview still shows the new value but the combobox is empty! NOT COOL!
Me.Show()
Me.WindowState = FormWindowState.Normal

I have some very simple questions about making a release build exe in vb.net using MS VB 2010 Express.
I realize that my project's executable is built in the bin/debug folder. However, when I copy this to any other location on my computer or someone else's, this executable does not function. I have read that I need to create a release build but in MS VB 2010 Express, when I use the Project-Properties menu and change the Compile tab configuration to Release and the path to binRelease, I still get the exe in the binDebug folder and not the binRelease folder.
1) Is it normal that exe's from the debug folder do not function outside of the debug folder?
2) Most importantly, if the release build produces a faster exe, could someone please explain step by step how to do this with MS VB 2010 Express ? I do not see any button on the compile tab in the project properties that actually builds the release.
I am using VS2008 on Windows XP SP3. I have a form with two pairs of dependant comboboxes which are bound to a SQL database table. In each pair, the second combobox's choices are dependant upon the selection of the first combobox.
Both pairs of comboboxes behave as expected. However, when I use the binding navigator to look through other existing records, the text in the second pair of comboboxes disappears on records that already have selections.
The database table still holds the information, but it just doesn't display in the combobox. Again, this only happens on the second pair of comboboxes, not the first pair and both sets of comboboxes are set up exactly the same (albeit on different tables).
We have a question regarding VB.Net 2008. We are used control array in vb.net and third party timer controls. When handle received from external application to timer control event procedure, after this form becomes blank and controls disappear. What we have to do to persist the controls.
