I am having a problem with visual studios 2010. I am creating ASP.net pages, but when I test/debug my code, the code-behind files runs the same code that was run the first time it was debuged this session. Meaning, to test new code-lines, I have to restart Visual Studio altogether?
View 1 RepliesCurrently, I'm testing the timer function.
I used the following code for my form:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
I have a problem with this program
Form1.vb
Imports System.ComponentModel<br/><br/>Public Class Form1
Public Delegate Sub updatePB(ByVal value As Integer)
Private bgworker As BackgroundWorker = New BackgroundWorker

Tried searching and found some related issues but none exactly like I was having
I iterate thorugh a DGV and write to one of the fields of the row. After it writes this field, I do an update() command.
Sometimes when you click view code on an item, it doesn't always automatically add in the private sub, why is this? How can I make it so it does? I dislike having to go on events every time =[
View 4 RepliesThe code I have is meant to be used during possible rapid mouse movement by the user. It is supposed to get the current location (works), move to specified location (works), mouse down(works), mouse up (works), then return the mouse to the old position.I added the delay because it seemed that it was having trouble registering the click if done too quickly.
The problem I am having is that if the user is moving their mouse during the time the code is activated, their movement can throw the location of the mouse down or mouse up events off even with the added check routine I added.
'Get current mouse position
Dim MousePosX As Integer = Windows.Forms.Cursor.Position.X
Dim MousePosY As Integer = Windows.Forms.Cursor.Position.Y
Q = True

I have a stored procedure that keeps timing out even though I have set the connection timeout set to 10000. The code that runs the stored procedure is this...

I am using an update panel and when I click a button it will update all the panels. updapanel1.update() is very simple, but my data is not updating unless I hit the button twice. My gridviews shows data for a selected user, and then all the grids reflect that users data. works fine all the update panels work for the gridviews. Now for somereason when i try to do a row count and update the panel with the summary, it does not work, i get either the previous users summary or if i hit update again for the same user i get the correct data.

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?
View 1 RepliesPublic Sub UpdateStaff(ByVal sr As StaffRecord)
Dim oldSr As StaffRecord
Dim q = From staff In db.StaffRecords Where staff.Employee_Number = sr.Employee_Number Select staff
oldSr = q.First
oldSr.Address_Line1 = sr.Address_Line1

The helper function I have written seems to do everything I want apart from update the db. Stepping through the code, the oldSr is updated by the new sr parameter but no update on submit changes.

View 2 RepliesI've one VB.net 1.1 based windows app. I recently added the app.config files. In code it works fine. But, when I compile the application, VS 2003 doesn't generate the appname.exe.config.(I read on google) I manually copied the app.config file to the Release folder. But the code is giving error that the file doesn't exists.
View 7 RepliesI am taking an Intro to Visual Basic class right now. When we do homework, we have to take it into class and put it into a folder that our professor has.When I save it onto my hard drive and I open it from Documents/Visual Studio 2010/Projects/HW Assignment 1, it opens everything perfectly. But on my flash drive, I have the same set up (E:/Homework Assignment 1) and I am not missing any files. But when I double click on the .sln file, it just seems to open the program without my project (display or code) showing.
View 3 RepliesI am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

I have a button inside of a gridview's template field. Onclick i want to the button to open up a modal popup while force updating the updatepanel and formview inside the modal popup because the formview's datasource depends on a hidden field in which i am setting after click also.

I have a vb.net project that has 2 exe's that get built as well as the installer. The two exe's share a bunch of common files. I do not want to have two copies of the common files or mess around with having build events that copy things around (if possible).
My method was to create two projects in the same folder and have them point to the files they needed. This appeared to work until I tried to compile both apps at which point I get an error in a file called Application. Designer.vb. It seems that project files create this file in their folder and when I have two solutions in the same folder they conflict. So my next effort was to create the second project in it's own folder and just add the items as needed. The problem here is that VS2010 doesn't hold a link to a file in a different folder it copies the file to the new project folder. What is the vs2010 way to get this done?
I am trying to write a string to last line of the text file by using timer 1 second interval. I tried use StreamWriter and Writeline but it looks like always write on the first line. Or I have to open the streamwriter when the form load and keep it opening?
View 4 RepliesWhenever I build my VB.Net project, the Assembly version does not automatically update as it is supposed to with the * in the third box in the Assembly Information. The only way I have found to (sometimes - it doesn't always work) get the version number to update is to Clean the Project, remove the *, Rebuild, reClean, put the * back in, and Rebuild again. What could be causing this issue to happen?
I should note that my coworker reports no such issue on his machine when Building the same Project; also, I must admit to some confusion on my part as to how this behavior is even possible, given that the error persists even if I remove every possible intermediate file I can think of that could possibly even be carrying the old version number, so how does it even know the old version number?
I'm doing a form to add/edit/delete values from a data catalog. everything goes fine but the Radgrid doesn't update after Submit Button is pressed in the edit/new dialog. i did it before in a more complex form but i can't figure exactly what's wrong.

I'm trying to update my database, I'm using access 2003, my problem is that for some reason I can update the first row but when I try to update any other rows after that I keep getting an error saying Column 'ProductID' is constrained to be unique. Value '7' is already present.

I've come across some strange behavior. I have a control that binds to a property like so:
<HyperlinkButton x:Name="ProjectBeheerLink"
Visibility="{Binding IsBeheerder, Converter={StaticResource VisibilityConverter}}"/>
In my viewmodel I have the property implemented like this:
Public ReadOnly Property IsBeheerder As Boolean
Get
Return iwtApp.AllMyFunctieRollen.Any(Function(x) x.Rol.Equals(Constants.RoleBeheerder))
End Get
End Property
Then when I raise my PropertyChanged event in my callback method
Private Sub GetMyPersonCompleted(ByVal lo As LoadOperation(Of FunctieRol))
'Init FunctieRollen ect. ...
RaisePropertyChanged(Function() Me.IsBeheerder)
End Sub
my binding does not update. However! If I implement a backend field like this:
_isBeheerder = iwtApp.AllMyFunctieRollen.Any(Function(x) x.Rol.Equals(Constants.RoleBeheerder))
RaisePropertyChanged(Function() Me.IsBeheerder)
And change my property like this:
Public ReadOnly Property IsBeheerder As Boolean
Get
Return _isBeheerder
End Get
End Property
Everything works fine...
I have an installer, and it installs some native dll's along with the program.The dll's are in a separate folder, which I added to the path environment variable.That was done successfully, and the variable shows up in path if I check the windows system settings.
However, if I start the command line program/service, it says dll's not found...I check the environment variable path with the set command, and my folder is not in there.If I do
SET path = %path%;my/folder/here/
And start my program after that, then it works.According to this MS KB article this is because the computer would need to be restarted.unless I do
SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM) "Environment", SMTO_ABORTIFHUNG, 5000, &dwReturnValue);
Now I did just that, using the below code, but the error message persists. My folder in %path% is correctly spelled, I checked that.

So, I'm working on a simple game in Visual Basic, and I have 2 labels. One named "pointsLbl" and one named "pointsleftLbl":
pointsLbl.Text = "Points: " & points
pointsleftLbl.Text = "Points left: " & pointsleft I also have two integers, one named "points" and one named "pointsleft". The problem I'm having is that when the point boost button is pressed, the labels don't update and also don't show the new points and new points left.

View 3 RepliesI have an editable datagridview that's been databound with dataadapter and datatable, and a normal button on a form. When i edit the dgv's cells and click the save button it fires the datagridview_cellvalidating event and if the cell validation is correct it updates and saves the current record to the datasource. Also, before save it commits change in any cell under editing. But when I use a toolstripbutton to do the same work, though it saves the dgv records but doesn't update the current change i.e. it saves the old records that are being fetched when the dgv was populated first during form load. Also, clicking the toolstripbutton doesn't fire datagridview_cellvalidating, datagridview_rowvalidating etc events. What it seems to be is it's not committing the change in any cell under editing. [Code]
Why isn't it happening and how can I make it work? how can I fire datagridview_ cellvalidating, datagridview_rowvalidating and other events; and commit cell value change by clicking toolstripbutton.
