• Visual Basic How do i make a vb.net 1.1 client side web browser object

  I have looked every where, why is there no working examples of making a client side web browser object. You could do it in old vb. And people say you can do it in vb.net, but only give half explained info, that does not seem to work. I have come accross pages saying you can just make a program or user control, and just embed it using object on you web page. but they never give full examples, or do not work. most say make a dll, but you can't share a dll on IIS, so i used another web server, and they still dont work. i need a full example, including web page I got it to work finaly, seems it dont work if the ...Show All

• .NET Development When to use TableAdapter.Update(DataTable) method?

  I'd like to know how can I use the TableAdapter.Update method so that I can update the database that I use whenever a user adds, modifies or deletes a row in a datagridview control. I suppose that I should handle the CurrentItemChanged event of the BindingSource that the DataGridView uses but I'd like to see a full example. In other words I'd like to create a WinForms application with a DataGridView that has the same capabilities as the DataGrid form for the Sql Tables in the Sql Server Management Studio. I know that it's a lot to ask but nevertheless this is something that is missing from the .NET Framework examples and walkthroughs. ...Show All

  Ok.....I have a while loop that executes an increment on a counter for a couple thousand times. I want to be able to show the progress on the counter using a progressbar. Now, I am executing the while loop in the DoWork method of the background worker and updating the progressbar in the ProgressChanged method and when i call RunWorkerAsync then things go wrong.

• Visual Studio Express Editions += and conversions

  I have recently switched to VC++ 2005 express edition, and noticed warnings in my projects which weren't there before. I'm not an expert, so I was wondering if the compiler is right in warning me about a conversion in this code: void main() {     short a = 4;     short b = 2;     b += a; } test.cpp(5) : warning C4244: '+=' : conversion from 'int' to 'short', possible loss of data Where did the 'int' come into existence "b = b + a" doesn't give any problems - isn't that supposed to be exactly the same Hi, I'd better overload these operators and do some spee ...Show All

• Visual Studio Express Editions Can't find DLL at runtime

  First of all, I am out of my element, as my user name indicates.   I received a .DLL and a .LIB from a vendor and some sample code indicating what functions to call within the DLL.   I know nothing else about the DLL.   Support from the vendor is not possible.   I wrote a small program that references or calls one of the DLL functions and have successfully compiled and linked.     When I run the resulting .exe, I get the following dialog box:   “Unable to Locate Component   This application has failed to start because zgenrl.dll was not found.   Re-installing the ap ...Show All

• Visual Basic Migrating from Ms Access to SQL Server 2000

  Hi, Is there many changes need t o be done in order to change my DBMS. Currently, i'm using Microsoft Access in my VB.net program. however, i need to change the DBMS to SQL Server. So what should i do can i still use back the same coding what namespace should i include Hi there, Firstly, I would consider using the Access Upsizing Wizard to migrate your database from MS Access to SQL Server if you have not done so already. If you've migrated via a different means, then a good start would be having the database schemas for the two databases almost identical (you won't get an exact match because SQL Server 2000 has a couple of differe ...Show All

• Visual Basic Flusing mouse input ??

  Hello all, I'm writing a multi-form VB.NET 2003 application. I have forms A, B, and C (alongside a module that holds handles to the three forms). The app takes the user from Form A to Form B when a MouseMove event happens, it takes the user from Form B to Form C when he/she clicks a button on Form B, and finally takes the user from Form C back to Form A if a timer times out. My problem is in the last transition. When a timer in Form C times out, I close Form C and reinstantiate Form A (newFormA= new FormA then FormA.Show()), however, as soon as I show Form A, the app takes me to Form B. Debugging shows that as soon as Form A is loaded, ...Show All

• .NET Development Webservice: "The ASP.NET process identity does not have read permissions to the global assembly cache."

• SQL Server Cannot install 'SQL Server 2005 Express Edition with Advanced Services'

  I tried to install 'SQL Server 2005 Express Edition with Advanced Services'. First, I uninstalled the old version thru Add/Delete Programs in the Control Panel. My first problem was I didn't have IIS installed on my computer, but, I could not find it in the downloads section. Then the installation aborted because old version databases were in C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data. But, it would not let me delete them, saying that they were being used, even though nothing was running at the time that I tried to delete them.
