View 3 Repliesi have the following function in default.aspx i have webusercontrol which have 10 checkboxes and 1 button i want when i click on button1 of user control then it can access the function of default.aspx page ...if i dragged the usercontrol to default.aspx

How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

I 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)
I'm finding a dropdown in an ascxcontrol on my aspx in the following way.
Dim cp As ContentPlaceHolder = DirectCast(Page.Form.FindControl("ContentPlaceHolder1"), ContentPlaceHolder)
Dim ascx As UserControl = DirectCast(cp.FindControl("drpType"), UserControl)

Is there a faster way without having to acces all the elements on the page?

View 1 RepliesI'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

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).

ive two custom controls, which are used to draw and edit etc...(like paint but customized....) i want to save their images with a single click....So im using the Getimageofcontrol function to do it....its code is below:::
Public Function GetImageOfControl(ByVal c As Control) As Image
Dim rc As New Rectangle(c.PointToScreen(c.Location), c.Size)
Dim i As Image = New Bitmap(rc.Width, rc.Height)[code].....

I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?
Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?
View 9 RepliesI am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript function.
In order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there. Here is what comes up in Reflector for the AddAttributesToRender function in RegularExpressionValidator:

say you have a sub containing an io.streamwriter. That streamwriter is declared and used only inside that sub (and not as static). Should you still call dispose on that streamwriter or is it disposed automatically as it is no longer in use after that sub, until you call that sub again?

Is there a way to define an array inside of the sub call parentheses?
Private Sub sub_name(byval sString, arrString)
sub_name("Some Text", array.{"","",""})
What I've been doing is passing a string and using a split on it to break it into an array in the Sub/Function, but I was wondering if there was a way to make the array inside the parentheses. I've looked through Google, but I'm guessing I'm not asking the right questions or it's not possible.

This is a very basic newbie question, but I still haven't worked it out yet. I have a fair amount of code that I want carried out inside my Form1_Mousemove event, but I also want the exact same code inside the Form1_MoveClick event. I assume the best solution is to take all of the code and put it inside a seperate procedure and call it from both events? Or is it possible to call one of the events manually so inside my Mouseclick event, could I force a call to the Mousemove event?
