View 1 RepliesI've got this variable iCurrentScreen. I've got a breakpoint on the line of code that writes something to the event log and I've made that breakpoint conditional so it only breaks when iCurrentScreen =1. However, whatever's setting it back to 1 I don't seem to be able to track down. Before I go putting breakpoints on every line of code that changes the value of iCurrentScreen . is there a way to tell the system to let me know when iCurrentScreen becomes 1 no matter where it happens?

View 4 RepliesWhen i test a project i usually press Ctrl+Break to pause the execution to change a value here or there, but unfortunately VB opens a new tab titled "No Source Available" and it become difficult to back to the tab that i was working with specially when there are a lot of opening tabs.
Is there any option to stay on the current tab when pressing Ctrl+Break?
So I have some vb.net code, and I have a nested For loop inside a For loop, and then I have EXIT FOR statement, will it break out of one loop, or the whole chain?

-VB6 and VS2008 IDEs use Ctrl+Break to pause execution for debugging.
-I need a way to map another key combination to trigger a Ctrl+Break
My setup may make this easier or harder but to be clear I am running Kubuntu 9.10 (latest stable) and WinXP in a VirtualBox VM. Obviously all VB6/VS2008 dev is taking place in the virtual machine.So maybe it's possible to have the linux host send through Ctrl+Break based on a key mapping, or maybe it's possible to remap directly in WinXP. I'd settle for any solution as atm I need to use the XP On-Screen keyboard to send a Ctrl+Break.
The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

I have a variable declared in the 'Form1' class and I want to change it in a sub in different class to a different value, and then use it agin in the 'Form1' class. However, I don't seem to be able to change the value in a different class. Is there any way I can rectify this?
View 3 RepliesI have a variable whose scope needs to be global, because it needs to be called in a function as well as in a button press. So I declared the variable in a Module so it would be global.The problem is that the value of this variable needs to be equal to the value of the text property of a textbox in the form.You enter a string into the textbox, in this case I entered "Hello". Then you click the button and it displays what you wrote.You click OK in that message box and change the value in the textbox. In this case I changed it to "Goodbye". Then I hit the button again, but the variable did not change values and the messagebox displays "Hello" again.

In some part of my code i need to redefine the type of variable that was defined with a different type at the beginning

*****What do I put here?*****(when exp reaches 1000)

what i want is that idx keeps incrementing after each line, without incrementing it on a seperate line.
I'm trying to make an application to do mathematical equations, but I also want to implement error checking. So that if someone doesn't put anything in one of the fields the output textbox will say "Error".
But the problem is that I already declared the variables I used as a numeric value, in my case decimal.
So, when I make an if statement that says if inputbox1="" then outputbox1="Error" it doesn't work.
I think that in order to get this to work I would have to have it setup so that the variable that is exported to the text property of outputbox1 could switch between being declared as a decimal or string value based on what the user put into the textboxes. But I'm not sure how to go about this. Declaring the variables inside the if/elseif statements won't work because the variables need to be declared before they are calculated within my if/elseif statements.
I'm multiplying X*Y*Z in a loop of 200 interations Y is declared as a constant. A timer can cause the loop to pause for 10 seconds.
During this 10 sexond pause I would like to change the value of Y. It needs to be changed only for this run, not a permanent change which can be done in the declaration.

I use:variablename = listbox.text
in the listBox_SelectedIndexChanged event and this works.
When I use the button_click event I use:
variablename = listbox.selectedindex
But this does not work in the listbox_selectedindexchanged event.you let me know if it is okay to use it like I did above or if I will run into problems and why you cannot use the selectedindex method.
I have a MainPage - mainpage.xaml Inside the MainPage I have a frame that hosts other pages. The first page that is auto loaded is the LogIn - LogIn.xaml
The user enters their email to login (no password required, just email to identify, its an internal app so passwords are not required or even wanted by users).
On MainPage.xaml the header should have a "Hello " TexBlock (name: ui_txbUserName). The LogIn page has a method which on submit gets the UserID (for other reasons and saves it) and the User Name.
I want to change the ui_txbUserName when the person logs in and update if he/she logs out of one account into another. I have looked at INotifyPropertyChanged and Dependency Properties and im just not sure how to go about doing this!
