Call A Function From Inside Another And Suspend It Until The Called Function Is Finished

Jan 25, 2010

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.

Does Subroutine Called By A Function Have To Finish For Function To Proceed

Jun 5, 2011

If a subroutine is called within a function, does the function always wait until that subroutine is completely finished before it will proceed with the rest of the function? If so, is there any way to make it not wait and continue on with the rest of function and not care what happens in the subroutine?

Asp.net - Insert Function Is Called More Than Once?

Jul 10, 2011

I have a website where people send each other messages Recently I noticed that sometimes the same message is sent more than once
For example, a message is sent four times within three seconds or twice within a second.I do not understand how this could happen, once the user clicks on the button that sends the message .So all the window switches and a message showup saying "the mail is sent successfully." I checked that if the user refreshes the page after it sends a message, then really the message is sent again.But I do not think that's the case, becouse the message is sent twice within one second.I am writing in vb.net and using mysql data base.Maybe it's related to the queue for the db, i do not know.Here's the code:

Function calls:
Call GlobalFunction.update_mailbox_table(user_id, receiverId, txtMessage.Text, private_picture)
the insert function
Public Shared Sub update_mailbox_table(ByVal user_id As Integer, ByVal receiverId As Integer, ByVal message As String, ByVal[code].....

Function Not Getting Called, And Program Stopping?

Apr 18, 2011

I have a function to pull data from a XML, and to report a specific number based on a value in one of the elements in the XML. Unfortuntately, I can't get any break points to work, so I've been debugging with a trace.he strange this is that when i take out the function itself it works like it should, otherwise the Service freezes when it gets to the function and never uses it. I'm calling the function in while loop which is also within a Try Statement, here's example of the code.

Public
Shared Function GetXNumber(ByVal
audit As Audit.API)

.NET Shared Function If Called Multiple Times Simultaneously?

Consider I have a shared function:Public Shared Function CalculateAreaFromRadius(ByVal radius As Double) As Double

If I have two or more threads in the same vb .net app and each of them calls the shared function at the same time with different RADIUS, will they each get their own AREA? I want to know for each call to the function if it is using same local variables or each call creates new instances of local variables?Will the answers to above questions be same If I have multiple (2+) single threaded apps and they all call the function at the same time with different RADIUS value?

Asp.net - AutoCompleteExtender WebService Fail To Be Called When Function Is Shared?

Oct 25, 2011

I had a problem (which is now fixed) but I've no idea why.I have an Ajax AutoCompleteExtender with a WebService method to populate like <WebMethod()> _
Public Shared Function populateACE(prefixText As String) As List(Of String) However this didn't work - I put a breakpoint in, and it didn't even get hit. However... <WebMethod()> _ Public Function populateACE(prefixText As String) As List(Of String) does work (the only difference being not Shared).

Fair enough, but why? If you have an instance of a class then you can access Shared methods of it; if you don't have an instance of a class then you can access Shared methods of it. So what is going on behind the scenes?

Terminate Process - When The Last Function Is Called It Terminates The Execution Of The Application?

Sep 13, 2011

I have this on the form load;

Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Visible = False
Me.ShowInTaskbar = False[code].....

Notice: I used "End", to terminate the process.What I want to do is when the last function is called (Delete_AutoReq_PracNo) it terminates the execution of the application.

Reason...I'll schedule this application to ran from MS SQL Server at night. So realistically, doing all the processes I would like it to stop...Is what am doing sufficient to stop the application from running or there is a more robust approach..

Function - Convert C# Code - Compiler Complains That DataBound Can Not Be Called Directly

I've been having trouble converting the following fairly straight forward c# code into vb.net 4.0, which I understand has anonymous delegates. I just havn't been able to figure it out yet.

I have tried the following

_combo.DataBound += Function(sender, args)

Have A Column In The Datatable Called Amount And A Textbox Acting As The Filter Called Say Maxamount To Set It?

Feb 9, 2011

i was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?

Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails.

Properties - Default Property Set Being Called Mysteriously Called?

Apr 2, 2012

I have the following line of code in my program:

JCL_History.Enqueue(JCL_History(I))


This JCL_History object is basically a Generic.List encapsulated in a wrapper and has the following method:

Public Sub Enqueue(ByRef value As String)
If Members.Contains(value) Then
Me.RemoveAt(Members.IndexOf(value))

[Code].....

In my testing I have 2 items in this JCL_History list. When I call that first line of code I posted (the one that invokes Enqueue) with I = 1 I expect the first item to be shuffled to the bottom and the second item to be shuffled to the top.

After the thread returns from Enqueue I notice that this is exactly what happens to my list, HOWEVER if I hit the "step_in" button after the execution of Enqueue I go into the Default Property's set method where Index = 1 and value = and it screws everything up, because the item that got shuffled to the end (index 1) gets overwritten by the item value shuffled to the top.

So basically the set method on the default property is getting called at what I think to be a completely ridiculous time. What gives? By the way I'm running VS2005 on XP.

.net - SSRS Report Called From ReportViewer Control Displays No Data In The Report When Called With A Parameter

Apr 11, 2012

Can you look at my coding and let me know what I'm missing or doing wrong?I have a SSRS report that is called from a ReportViewer control and the ProcessingMode for this control is Remote. The report also has 1 parameter in it's DataSet.In the code I placed a MsgBox to make sure the code is finding the parameter and returning the parameter name. I am trying to stick the value of 10 into the parameter for playerID 10. Data for this player does exist.

I believe I need to add some more code to make this work but I'm not sure what else to add.

When the code executes the report is displayed but no data is shown in the report.
