I'm selecting multiple files from a FileOpenDialog box. Now I want to store the names in an array. This is what I'm trying to do:
For i = 1 To fileOpenDialogOpen.FileNames.Length
ReDim Preserve fileList(i)
fileList(i) = fileOpenDialogOpen.FileNames(i).ToString()

how do I set an object array using a loop so I don't have to type each button name?
[code]...
only problem with that is it assigns a string value. I need it to assign an object. any suggestions?
I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.

Ensure that the order of the places is the same in both arrays. When the names are places are input the distance between them is displayed.

I think the best way forward is pass a parameter to the function findnumber.

The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

View 2 RepliesI am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.

I'm trying to convert old code to VB in VS2005. The code I'm working on is used to store values in a string, which will then be handed to a proprietary scramble function. This function is a given in this case. I've already switched from a string to an array of bytes in my .NET code.
The old code (VBA) was using a string value to store the data, example function for Double value:
Private Function DoubleToStr(ByVal value As Double) As String
Dim Bytes(7) As Byte ' 0-7 Double is 8 bytes
Dim n As Long
CopyMemory(Bytes(0), value, 8)
DoubleToStr = ""
For n = 0 To UBound(Bytes)
DoubleToStr = DoubleToStr & Chr(Bytes(n))
Next n
End Function
The code basically copies the memory contents (using API call CopyMemory) of the memory (held by the double variable) to the memory held by a byte array. It then reads the byte array and converts it into a string. Workarounds could be to convert a bool or long to a string, though that would be expensive in terms of memory/storage eg. 1234564787 would be 10 bytes in a string where as a long is only 4 bytes (factor 2.5 increase).
How to retain the original precision? Converting it to a string would result in endless numbers. Another problem (at least I think it could be) is that in VBA the variables are rather simple, but in .NET they are all objects, so how to retrieve the actual memory location of the value? let alone garbage collection moving stuff around. How to get those variables stored in my byte array?
I'm writing a program that reads randomized test questions from a text file. The text file includes information about how to set up the screen including which pictures, videos or buttons etc. to show for each question. The user responds to the questions and another text file is created logging the results. would it be better to read in all the data from the text file into an array to work with during the test, or should I just read the questions one at a time keeping the text file open while the user responds. The amount of data that would be read into an array for an average test would be about 200 lines which range from a single character to 20 sentences (whose length would of course vary).
