[Code] i need a way to screen each employer status and mapping status before placing them in the DGV. I need to convert the numerical values to their corresponding status. 1 = Good, 2 = Non-Reporting, 3 = Under-Remitting and 4= Non-Remitting(which i already know how to do). I just don't know how to get the values being placed on the DGV. I would love to do this on oracle but i don't know how to.

View 1 RepliesI need help to form a code for a small arrays manipulation. The input data are known: they are two integers "N" and "s". An integer "N" is always divisible by 4.I need to create an array of "N" members, by repeating (N/4 times) this sub-array: 1,2,2,1 (always is the same). In the picture, this is shown in blue. Then I need to add the same array to the existing array, but shifted for "s" places (red array). The result is "yes" if each sum in new columns is always the same (3). Otherwise the result is "no." note there is no need to draw or display something (DGV, table ...). The required result is only "yes" or "no".

I'm currently learning VB.net and can confidently connect to databases and return results to comboboxes run stored procedures ect to datagrids, However I'm wanting to find an online tutorial for doing loops with data so for example
I return the following data into a dataset
Orderno Orderitem Price GUID
111 Pies 1.50 xxx-xxxxx-xxxxx-xxxxxxx
111 orangutang 2.00 xxx-xxxxx-xxxxx-xxxxxxx
ect
I want to display each element on a page in a structured format so as to make a visual representation in seperate entities (labels maybe) of the data like so:
Order number
line 1 (includes item and price in plain text on a page i guess using a label)
line 2 (same goes)
Subtotal( )
The results and formulae i can do but it's simply how to split off the data from my dataset and display elements as seperates (also how will i dynamically create the lables as obviously i'm not going to know in advance how many order item rows will return )
Obviously this is not urgent but if anyone could point me at a tutorial or even better a few lines of code that will do this for the microsoft northwind data so i can mess about with it and play.

View 4 RepliesMy next step is to allow a pause checking the status of the motor and or inputs before going to the next step. Reason is so it does not do many calls to the motor controller so fast. I need some help building a loop that checks status of the motor and if Motor1Active is 1 which means it is running that it needs to wait a bit and then rechecks itself. If it is not running it will continue to the next step command. Here is a sample of what I got but need to figure out say a 50ms wait before rechecking. I guess a loop that rechecks and waits 50ms and then rechecks the status and if done and reads 0 then it goes to the next step. if still 1 output data it waits 50ms and then rechecks. The following is what I got started with but need help with if then else and anything else statement.

View 2 RepliesI've created a form with several controls to specify the inputs to my program. They include TextBox, OpenFileDialog, Button and even a user control for numeric input. When the user clicks the 'GO' button, the program begins it work. Opening several files and processing a bunch of numerical data. This could take many minutes/hours with large datasets.
What I've been trying to do is have another window/form open up and send status information to it for the user to view. The info to be displayed is varied and constantly updated as the program crunches the numbers. Many many programs do just this type of activity.
I attempted to create a second form with a huge TextBox thinking I'd just write stuff to it. I called the .show method within the .click of the 'GO' button and of course the form is displayed but control of the program's execution doesn't return until the form is closed. How to I maintain execution and have a second window/form to display status?
BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?
