View 3 RepliesAnyone 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.
Here is my code:

I have just opened VB10 for the first time and it converted my VB8 program beautifully, except that all of the screens are not showing any data !
My reference to the MS Access database file is as follows :-

Do I need to change any of this syntax or is there some other reason why VB10 won't show anything ?
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 try to determine the lenght of a string variable, but get the wrong outcome when using: testje = Len(testSTR). 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?
View 11 RepliesI'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
[code]....
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)
The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
