I have the following statement and the function 'InitialiseOsTransform' is in a Module which is in the project.
If InitialiseOsTransform() = False Then But instead of the code going into this function it goes into the Paint function.
I have used the similar code in another project and it works correctly.

View 2 RepliesI've an app that starts to work from a module wich should load a form an do other things with a class library who raise an event an the form shoud cath it. The problem is that applicarion.run(frmMain) displays the form in the same thread the the code stops work while the form is open. And I need that the app works in this way because the user need to send files to the app using args and this avoid that the app init another instance of it (in other code) and update the form with the info when the event is raised.

I would like to allow my users to decide where they want their data to reside. I have created a data source which is referenced by crystal reports. I would like to replace the |DataDirectory| to point to a path the user selects. or if possible substitute it with vb function.
Below is the line in xml that point to my db. I would like to allow it to call a vb function that will return my db path I am not sure how to replace the connection string by using a vb function in xml.
<Connection ConnectionStringObject="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|MY_DB.mdb;Persist Security Info=True;Jet OLEDB:Database Password=pass" IsAppSettingsProperty="false" Modifier="Assembly" Name="MY_DB.mdb" Provider="System.Data.OleDb" />
I would like to replace |DataDirectory| with the result of a function called MyDBPath(), can anyone assist.

I am writing a control application for an inteface card. The complicated work of initialising communication with the card is written and working fine. However, my problem is to update the text in a dialog label on the communication interface form from a module that contains all the coding for accessing the inteface card. From the module, the interface dll returns data that describes some typical connection errors and the module then calls on Public Subs in the form to display error messages; for example:This is the Public Sub in the Module that initiates communication with the interface card:
Public Sub OpenDeviceInterface()
DeviceID = 1 - My.Resources.DeviceID
h = OpenDevice(DeviceID)
Select Case h
Case 0, 1, 2, 3
[code]....
What happens when these Public subs are called from the module is that the MSgBoxes I made to test the routine show up but the label text doesn't appear.I've tried; Refresh, on the label and the form without success...

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.
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?

View 3 RepliesI 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)

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.

file_send is the function of dll .
prg_Timer is the timer control .
Prg_bar is Progress bar control.
I have an 100 aspx files with one module file for code. All these aspx files have the same backend function, so i created on public module for all these files to access. These files are in the same folder. But for some reason the aspx files cannot access the function from that module.
mod1.vb Code (.vb file)

I am at a roadblock of why the aspx files wont read this module? Also all these files are in the same directory
I have a console application consisting of two modules. One module named "quote" is the main module for the application. Another module named "common" contains commonly used functions and subroutines that are shared between multiple applications.
In the "common" module is a function named "quote". If I attempt to call the "quote" function from the module named "quote", then I get the following error: Error 1 'quote' is a type and cannot be used as an expression. However, if I copy the quote function from the "common" module to the "quote" module, then I no longer receive this error.
There shouldn't be an issue with calling a function that happens to have the same name as a module, but only when that function is located in a different module.
I have a problem regarding calling the function in form to the module..i have 2 module which is User Login Module and the other Module is Update the Fields of Student..my problem is the Update Module when i call the function in form i cant call the function that i used..this my code in udpate module and this is my code in form The UpdateExeQuery that i use in module.when i call in the form its error..
View 11 RepliesI've written a series of ASP.NET pages which have several common methods among them. In my ignorance, the best way I was able to find to move those common methods to a separate file was in a Module. However, what I need is a way to identify from which page was the method called?For example, I have a method call WriteToErrorLog with the following signature:WriteToErrorLog(ByVal sender As Page, ByVal Source As String, ByVal Message As String, ByVal StackTrace As String)
View 1 Repliesi started with 1 solution, 1 project a usual. Then i did it again, different project. Then, i wanted to have the 2 projects in 1 solution - so i copyed the project folder from solution 2 into the folder of solution 1 and added as existing project the project 2. So far so good.
Now i have a module with some public functions in project 2, that i want to use in project 1 as well. So i added to the solution a class module (some classes i want to share also) and i moved the module, (that i want to commonly use) into this class library. But it seems wrong - my application does not find the function again.
Consider I have a shared function:Public Shared Function CalculateAreaFromRadius(ByVal radius As Double) As Double
[Code]...
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?
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?
