TreeView With "Recently Chosen Paths" Option

Jun 26, 2009

I have a treeview that I use regulary. During testing I usually got to one of three locations in the treeview. However I have to drill down quite far in the TreeView to get to these locatons. The Treeview Parent node is "C:"

I would like to build some funtionality in so that I can present the user with a list of commonly chosen paths and then have the treeview reload and generate the full path from the list. Maybe this would be generated off a right click menu. Not really sure exactly the best way to do this.

Validate That The Chosen Option Is Appropriate For The Rest Of The Row?

Aug 21, 2009

I've searched for a solution with no luck, can you help? I've a DataViewGrid with a DataGridViewComboBoxColumn, bound to a dataTable which all works fine but I need to undo the user selection in some cases.

When the user selects one of options I validate that the chosen option is appropriate for the rest of the row. I can do this in the CellValueChanged Event and easily determine if its good or bad - is this the correct event to do the check?

The problem I have is that I want to roll back to the default value in the DataGridViewComboBoxColumn if an invalid selection is made:

DBConcurrencyException When Editing A Recently Added Row?

Jan 19, 2011

I have a DGV that is designer generated. I can create a row perfectly fine, and I can edit rows perfectly fine. However, if I try to edit a row that I have just added and saved, i get a concurrency error. As you can see in the code below, I perform some "injection" of information into the rows before they are pushed back to the database.

System.Data.DBConcurrencyException was unhandled
Message=Concurrency violation: the UpdateCommand affected 0 of the expected 1 records.
RowCount=1

I am developing an application in VB.NET. in which I need to open the most recently accessed file (i.e. last accessed file in the previous session) when the application starts.

[2008] Generating Exe From Recently Converted VB6 App?

Nov 13, 2008

We have an application that was written in VB6 which I am trying to convert to use the latest VB (Visual Studio 2008), mostly because it's not possible to buy a licenced version of VB6 anymore (personally I'd have been happy to just keep using VB6, but without having a proper licenced version of it, we basically had to chance).The VB6 version I could simply tell it to compile the application and it produced the .exe file which I could then copy onto the server where it was running and replace the old version and then run it.

It seems like such simple things are not possible in VB 2008.I have got the application converted, and if I run it through the debugger it is working correctly, but now I need to get a compiled application to run on the server and can't seem to do it.I have tried using the publish application thing, and nothing I try succeeds in getting a working application.

Asp.net - Identity Of Recently Added Record And Insert From Gridview?

Jun 24, 2012

I am developing an ASP.Net VB Web Application

The application contains a GridView which displays the records of a user table from my created datable. The database is an Sql server database.

The code below inserts data into one table and through the built in function @@Identity to insert the most recently added record id (tt_id) from the trainingTbl table and inserting that record id into the userAssessmentTbl. Adding the identity to the second userAssessmentTbl table works fine.

[code...]

The issue I'm having seems to be centered on how I insert a uniqueidenifier from a GridView into a userAssessmentTbl database!

And how, I guess using a loop I can insert the UserId records from that Gridview (GridView1) into the userAssessmentTbl table along with the looped id from the @@Identity.

This part of the insert parameter seems to be incorrect:

[code...]

And the error I'm met with is: 'Conversion failed when converting from a character string to uniqueidentifier.'

I've also tried it like this:

[code...]

And im met with the error: 'Operand type clash: int is incompatible with uniqueidentifier'

The qusetion has slightly changed to how do I Insert a String into SQL DB Where DataType Is Uniqueidentifier?

Stopwatch - Selecting The Most Recently Dynamically Created Object With .NET?

Feb 3, 2012

Below is some code that I'm using to create objects with Visual Basic:

For indexCounter As Integer = 1 To TotalParticipants Step 1
participantClock = New Label
participantClock.Size = New Size(100, 20)
participantClock.Name = "participantClock" & indexCounter

[code]....

I'm creating a label, a button, Timer, and Stopwatch. (Though I have sinking feeling I don't need BOTH a timer and stopwatch since I'm counting time.)What I would like to do, is create the label and set that label's text to be the value from the stopwatch. The button that will be created will stop THAT stopwatch.

The problem that I'm having is that I cannot call the stopwatch by name since it wasn't created yet and VB throws a hissy fit at me for it. (After all it wasn't really declared.)So the question becomes, how do you call the most recently dynamically created control and assign events using that control. If it's not possible to do, I do not mind dumping the form and starting over creating 30 stopwatches instead (but I'd like to avoid that, if possible).

Can VB Play Clips Of Randomly Chosen Avi Files

Apr 3, 2011

Can a media player written in VB be modified to do this: randomly choose an avi file from a directory or subdirectory, choose a random starting point within that file and then play a clip of a random length (within user defined parameters) then without prompting repeat this sequence?

I would like just such a media player but there doesn't appear to be one already out there so my only other option is to write one myself. I know nothing about VB and last programmed in BASIC in the 90s. Before I invest time and effort in learning VB I need to know if it can actualy do this at all.
