When I insert the following line of code: testje = testSTR.Length the answer is still wrong but when I click "Length" I see the correct value. How to get at that value, so I can use it?

Anyone got any ideas on how i would go about fading in/out a textbox? Because only forms have opacity properties i was thinking of something like setting the background color to transparent and setting the forecolor of the text to the same as the background color. Then using a timer i could slowly change it to black, etc.

View 2 RepliesI had an assignment that I had done, which has been turned in, I was able to get it to graph, but it when it reaches the right side of the screen it drops off, when it is is adjusted using the velleman controls it jumps back up, hw would I fix this.
Here are the instructon for the assignment:
Write a program tat rads two analog inputs from a velleman board and plots the values on a rotating graph. The number of value plotted horizontally should be specified in a text box. Label the graphs vertical values in at least three places. Print the current voltage reading for each input in it's own lable. The graph should auto scale to fille the graph vertically and horizontally.
The two things that I couldn't get to work is the graph drops off the chart and I was unable to place the vertical values in three places.

My reference to the MS Access database file is as follows :-

How can I set the width of a form in inches (or cm) instead of pixels?
I want to print the form, so it needs to always be the same dimensions (4" by 6"). I saw some examples for previous versions of VB, but nothing that works in VB10.
I recently finished a class that we're using to tie Access to some WCF Services. Of course this means that the .Net classes (and all of their properties) need to be visible to COM. Given that I'm using VB10 and the Contact class has about 20 properties I went ahead and used auto-implementing properties.Much to my surprise, the properties were not accessible from within VBA in Access. I tried marking the properties as ComVisible (which I didn't have to do in the past with standard properties) and it still didn't work. After changing the auto properties to standard properties everything worked.

View 10 RepliesI am developing a simple application in VB10 that uses ADO.net to store data in an Access database, and gets input via a serial port RS232. It works well, but is not fully debugged. Unfortunately, a problem has recently started where as soon as i close the program I get a blue screen. Makes it hard to debug. The solution does not even have to have run; it just has to have been loaded and then exit VB10. The blue screen aslo happens to most of the other example solutions that I have downloaded.
Questions:
1)How do you capture the STOP error codes (probably stupid question)?
2) Is there an easy solution that rings a bell? My IT support is trying but not getting anywhere. Have to believe it is hardware related, but the hard drive checks out with testing.
I've been using the vs2010 beta but I can't seem to get edit and continue to work.
Compile -> Advanced Options -> Target platform is set to x86 (Compile -> Platform is disabled and set to Active (Any Cpu)?).Options -> Debugging -> Edit-and-continue is checked but grayed out. Presumably for the same reason I can't debug.Options -> Historical Debugging is set to Events Only. Disabling it doesn't help.I get no warnings when trying to modify files while debugging, they're just read-only (shows a lock icon in tab).
What are some other options that might be disabling edit-and-continue?

View 5 RepliesProblem in VisualBasic 10 on Windows 7 OS I have a form which has 30 lines for user input in format <textbox for Name> <comboBox for Type> <comboBox for Quality> <NumericUpDown for Amount> At the start of each line is a CheckBox. The intention is this enables/Disables the line. I have associated each object with an Array - eg
Dim Name(30) As Textbox
etc
and assigned
Name(1)=Name1

ie enable/disable the boxes on a line dependent on whether CheckBox is Checked The Sub for Picked_Changed refuses to allow referenced to the arrays within, even if not generated by the picking of box (see above - it allowed '=Men3.Value' but not 'Men(3).Value', although the button sub is fine with this)

View 9 RepliesI need to take the items in a listBox and post it in a textBox with a delimiter. I worked some code but it does not work correctly. I think my array is wrong but i am lost. what happening is when i click button it highlights an item in listBox and then adds it one item to the textBox x number of times of items in listBox. so if i have 4 items in listBox it adds same item 4 times. anyway here is what i have.

I need my program to check and see if it contains any of the items in an array. For instance I want the program to only filter .jpg png bmp and gif in a listbox when files are added, so I did this
If str.Contains(".Jpeg") Or str.Contains(".png") Or str.Contains(".bmp")Or str.Contains(".gif")Or str.Contains(".wmf")Then end if I want to have a a list of all these filetypes in an array or so and have it only checking in the whole array instead of typing each one.
I have a small program that talks to a server, grabs the content from a website using a php webscraping program and then places the results in a listbox as a string.
