No Screen Updates While Processing In Visual Basic?

Jul 25, 2009

I am using Visual Basic 2008 to create some databases. It reads data from textfiles and puts them in SQL databases. After the user presses the Process button I would like to give the user to get some feedback of the process simply by for example label1.text += "Processing File 2".But during the process no Screen Updates are made...only after all databases are processed and VB.net is waiting for new user response it updates my label1.text

Visual Basic 2008 Updates Wrong Record In A MS Access 2007 Database?

Mar 7, 2010

i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:

Screen Blanks After 1 Min Of Processing (of Excel File) / Refresh Or Freeze Screen To Avoid Blank Screen?

Jun 29, 2011

BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

Monitor An Area Of The Screen For A Certain Color In Visual Basic?

Apr 5, 2012

I'm designing a player application to accompany our phone system. As our calltakers take calls, it makes recordings of each call. They can go to a list module, find a recording and double click, which opens my player. The issue i have is that if the calltaker gets another call, my player doesn't know it and will continue playing. I'm looking for a way to monitor the screen in a particular area and when it sees yellow or red instead of blue, it will pause my player.

The phone system does not have any API's that I can hook onto, so I have to try it another way.

The screen resolution never changes and the queue buttons where they receive calls will always be static. When they get a call, a small area changes from the background color blue to yellow or red to indicate a call.

**EDIT Final Code based on answers below and question Memory Leak using GetPixel/GetDC in Visual Basic

Private Function CheckforCall()
Dim hDC As IntPtr = GetDC(0)

WinForms - Turning Off Screen Updates By Setting Echo

Aug 13, 2009

In Microsoft Access there was an easy method to turn off screen updates by setting Echo = False. Is there an equivalent in VB.NET for WinForms? I've got a situation where I'm trying to prevent users from seeing controls flickering while they're being updated. I could probably solve the problem by coding it differently, but would rather avoid it if I can.

.net - Which Version Of Visual Studio 2010 Contains Visual Basic SharePoint Templates

Aug 5, 2011

Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.

At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates

Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

Multi-threading Processing - Processing A Large List Of Records And Inserting Them Into SQL Database One By One

Mar 18, 2011

I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.

I have code look like this:

Private Sub btnLoadNow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadNow.Click

Dim autoLoad1 As New Thread(AddressOf AutoLoad)
autoLoad1.Start()

[CODE]...

Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?
