I'm trying to do this[code]...
But it still runs asynchronously. I need the browser to actually wait until my code-behind is finished executing, then it can be refreshed
There's a listbox loaded with values that were just deleted from the database, they shouldn't be visible. Problem I have is the window location refreshes before the code-behind is executed, and nothing seems like it was deleted to the user.
I am trying to use PageMethods to call a function from the server side, but I am getting an error that PageMethods is undefined.
Here is what I have put into the html
<asp:ScriptManager ID="ScriptManager1" runat="server"
EnablePageMethods="True">
and here is the function from the code behind.
<System.Web.Services.WebMethod()> _
Public Function LoadChild(ByVal EntityID, ByVal EntityCat, ByVal lnType, ByVal FullExpand, ByVal lnEquip, ByVal lnTemplate) As String
and here is the call to the function using page methods.
PageMethods.LoadChild(lnEntityID, lnEntityCat, GLOBALEQUIPID, FullExpand, 0);
can anyone see why I would keep getting a PageMethods undefined error?
edit - part of the issue may be because the function isnt shared, but when shared is put in, i get this error in about 15 places. - this is refering to the session I am using - here is a snippet of the session being used that is showing an error.
prm4.Value = Session.Item("user_id")
I am getting the word session underlined with the error message below - any suggestions on how to fix this? this could fix the whole issue all together.
Error 305 Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
I'm getting "Me' is valid only within an instance method" error when I convert function to a PageMethods. [code] If I remove Me, I get different error.I got this shopping cart script somewhere online and I'm not sure what to replace "Me.objDR" with something else.
View 3 RepliesIs there a synchronous wait function that won't tie up the UI-thread in .NET WPF? Something like:
Sub OnClick(sender As Object, e As MouseEventArgs) Handles button1.Click
Wait(2000)
'Ui still processes other events here
MessageBox.Show("Is has been 2 seconds since you clicked the button!")
End Sub
I am running several long synchronous operations in my VB.NET application that can take several minutes each to complete. During these operations the form will turn white and the title bar will show "Not Responding" and some users may close the application thinking it has stopped working when in fact it is still running.I am pretty sure I need to multithread to do this, but my initial efforts have been unsuccessful. What is the easiest way to refresh my form every couple of seconds or so while these long operations are running?
View 4 RepliesI have a WinForms app and am trying to add the ability to start up multiple operations based on data entered in a datagridview. The operations must be run synchronously to monitor that they complete succesfully before inserting a row into the DB to indicate that the operation was succesfull. I also have a status event handler on the operation which will return the percentage of the running operation.
So far I am using threads to kick off the operations, however it is updating the progress of just one of the threads. When that thread is complete it is moving on the the next and will work that until completion. I would like them both or more to run simultaneously and be able to report the status of each.
I am basically looping through the rows in the grid and using the values there to instantiate a new class I created. I am then creating a thread and kicking off a sub to perform the operation from the new object. I think I may be close as I know they are all being started, but they are just running one after the other rather than all at once.
Is webbrowser.navigate method is synchronous or asynchronous?
example:
dim ct as integer =0

counter+=1
will counter get increased after firing webbrowser.document completed event?
I connected to the Informix server using RazorSQL, created a stored procedure and tested it, getting the expected answer, so the procedure exists in the database in some form.
I then run the following code:
If ConnectToInformix() Then
Dim cmd As New IfxCommand("dc_routeHasOutstandingQuantity", conn)
cmd.CommandType = CommandType.StoredProcedure
[Code]....
This error does not occur when calling the stored procedure from a live SQL connection.
I want to create an ExpressionTree where a Func(of Vector, Vector, Vector, Vector, Double, Double, Vektor) should be called. So I use
Expression.Call(Forces(0).Function.Method, {Vec1, Vec2, Vec3, Vec4, Double1, Double2})(Vec1-4, Double1-2 are declared as ParameterExpression and Forces(0).Function as Func(of Vector, Vector, Vector, Vector, Double, Double, Vector). But I get an AgrumentException, because Forces(0).Function.Method has seven Arguments. (System.Runtime.CompilerServices.Closure as seventh argument at Index 0).

I have a VB .NET 2010 application. I added a C# project to my solution. I tried to call the form called 'main'. However, I could not figure out a way to do that. What is the best way to do that?

View 5 RepliesDLLs in .net are treated differently than in C++ and other programming languages.When you create a class library project in VS (for either VB or C#) you are creating a DLL. In order to call/use that DLL in another project you have to add a reference to your new program.Go to Project > Add Reference..., or right-click on the project that needs to use your DLL, and click "Add Reference...".
After a short wait you should see an Add Reference dialog box.There are several tabs across the top but each of the components that is listed in a tab represents a DLL. If you expand the "Path" column in the .Net tab you will see the DLL location.If your two projects are in the same solution, you should probably go to the Projects tab and add the project that you need.If your dll project is NOT in the same solution as your project that needs to use the dll, then go to the Browse tab and find your compiled DLL from your DLL project. This will add the DLL as a reference to your solution.
Okay, this is my first newbie question so I'm sorry for this newbie question.I've look at Toolbox and I just can't find whatever this called.I don't even know what the name of it too so if anyone know what this called,

View 2 RepliesI have a Visual Studio solution, containing .cs and .vb projects, as well as .aspx files. As usual, the .aspx files implement an ASP.NET site and make calls to the .cs and .vb projects.
Is it possible to do the reverse... i.e. make a call from a .cs or .vb file to a method in a .aspx file? (Assume for the purpose of this question that there is a good reason for doing this)

View 1 RepliesI have created a new Class Library in visual basic and called it 'TestDLL'. I have a TestDLL.vb file where I put in this code
Class TestDLL
Function ReturnHello() As String
Return "Hello"
End Function
End Class
Then I clicked on the build tab and built the solution. I then copied the DLL 'TestDLL.dll' to C:TestDLL.dll
I am trying to use that DLL in a console application. I have tried this code but I get an error: System.EntryPointNotFoundException was unhandled Message=Unable to find an entry point named 'ReturnHello' in DLL 'C:TestDLL.dll'.
Declare Function ReturnHello Lib "C:TestDLL.dll" () As String I have added TestDLL.dll to the references for the console application and got that to work, however my goal is to load and unload different .dll files without restarting the application. I have a lot more code besides this, but I'm just trying to find out what commands I could use for just calling functions from DLL files.
There was something I was reading about assemblies, but all I get that to do is list the classes in my dll file. I will already know all the names and locations of the .dll files, and also the class and functions that they contain, because I will be building all of them. how I can get a simple function return in my console application.

I'm making a button via images, which changes appearance as the user uses the mouse. For example, when the user clicks on the button, the image changes into the button being "pushed in." My problem is that when the user presses the button and releases the mouse I want it to go back to the image when the user is just hovering over the button. This only happens if the cursor is move off the button and then moved back onto it. I'm trying to call the event/sub where the mousehover event is used in order to get it to change back to the desired image. How do I call this event and/or sub in order for it to work?
