VS 2008 Variable Changing - How To Stop It
Feb 18, 2010
The following procedures sorts a listview column based on what the tag is, 'Numeric', 'String' or 'Date'. When you click on the column header the sort procedure kicks in. On the first click it will sort ascending and on the second click it will sort descending.
My problem is that when I click a second time it won't sort descending but re-sorts ascending again.It appears when the sortorder is passed to the ListViewColumnSorter.vb classes it changes back to ascending even though it's called as descending. I've bolded the offending variables using a Numeric search.Now here's the really iritaing thing, I have exactly the same code in another application and it works perfectly?
Private Sub lvwResults_ColumnClick(ByVal sender As Object, ByVal e As System.Windows.Forms.ColumnClickEventArgs) Handles lvwResults.ColumnClick
SortMyListView(Me.lvwResults, e.Column, , True)

This is my code for a trial application. The code is pretty basic but what i couldn't figure out was how i would be able to prevent users from changing the date to extend the trial ("error" i would be getting).

There is an older version of the software which works fine on all of our deployment platforms, but the version I am trying to push out is working fine on 32-bit desktop installations, but is crashing-and-burning when it attempts to access Crystal Reports and Informix installed DLLs on a 64-bit machine, running terminal server sessions (yeah, I know, could I change anything more about the deployment platform?)One of the suggested avenues of investigation was changing the solution platform from "Any CPU" to x86.On attempting to do this, Visual Studio seems to stop being able to connect the partial classes constructed by XAML objects, with objects declaring that they have no "InitializeComponent" methods, and then failing on down the line until I reach the maximum number of errors.
Oddly, changing the solution platform, and then rebuilding in Expression Blend compiles just fine. Changing the platform back to AnyCPU makes the problem disappear. All projects have compile and debug configurations set to Active. I can't see any reason why simply changing the targeted platform would stop the XAML from generating partial classes Okay, it seems to be that there are some external DLLs to the project, and that those are the cause of what I'd call the first-level compilation failure, as they don't seem to contain any classes once the target platform has switched.In VS2008, this causes the cascading failure of absolutely nothing working at all, as described above, but at one point I somehow managed to import the project to VS2010 with only those errors in place (missing classes, etc.), without the rest of the project imploding.I'm now working on reconstructing those classes from those DLLs, and hopefully will be able to get together a project that will compile on multiple target platforms by the end of the day.

am running VB express (2008 edition). I have a class that holds 2 arrays (1 array represents the digits of the integer side of a number the other holds the decimal digits) I have overloaded all the operators to work with these numbers as if they were one. Each operator has the following format:
[Code].....
whats happening is that the sign of the b variable (and only the b variable) randomly changes. Almost allways at the statement bb=b (bb is in place so when I reach that point I know what the variable had before the calculation). I can watch it change as I step through the code (stepping over the operators) I can watch it change almost allways at the bb=b, but sometimes in other odd places (such as the d=a*yparam statement). I can change the values back to their original and step through the code(stepping into the operator this time) and it will not do it. It NEVER does it when stepping into the operator, only when I dont, and only sometimes. I have spent the last two days working on debugging this one problem, with every other variable in the function it works like it should and I am not sure what to look at next. I know it does you no good without seeing the code but didnt think pasting 8,000 lines of code would go over too well so I would be willing to send the source to anyone

When start is pressed i want it to click 2 or 3 different locations on my screen if this is posible with about a 1 second delay between each pointer move.i could really use some help with getting started or even better a link to an already created application for this.

Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

I am trying to use the value of one variable to call another variable of the same name.I have 2 variable one called VAR1 and VAR2.
The variable VAR1 has a value of "VAR2"
The variable VAR2 has a value of "HELP"
I want to be able to get the value VAR2 from the variable VAR1 I have defined the value of VAR2 early in the code and now I want to call that value by using the value of VAR1.The reason I am doing it this way as I have a list of 50 variables that are pulled from one system. Each of these variables have the same name as the columns of a spreadsheet. The total number of Variable stay the same but the total column headers may vary each time. I need to loop through each of the column headers match them with the variable names and add the data to the spreadsheet.
VAR1 = "VAR2"
VAR2 = "HELP"
i =1
[code]....
This is the tricky bit...if the value of the cell(1,i) = "VAR2" How do I get it to display the value of the variable of the same name In this case how will I get it to display "HELP" when I only have from the VAR1 value "VAR2" I know my code will bring back the value as a string but I want it to bring back that string as a variable and display the value of that variable?
