I need to save actual age (in whole years) for future use in the program. The problem is, 'Years' returns a big, fat 0 every time. Changing "Dim years As Integer" to Dim years As String" does exactly the same thing.

View 1 RepliesI want to change the color of the group header text in listview which separates all the items into various groups, there is no such option to do that directly because no such property exists.
As far as i can think of it can be achieved via overriding the paint event but i have not done any overriding of paint events on windows controls so far.
I'm using the following code to populate a DataGridView with a worksheet. This is working fine, however, I'm unsure how I can get the Text from the page header. (not to be confused with the column header). Later in my code when I am exporting into an existing workbook with a new worksheet, I'm wanting to use the header text as the tab name. The header text being "September 2009" so that when I import/manipulate/export october, the new tab will be "October 2009" etc. [Code]

View 4 RepliesI wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.

View 3 RepliesThe Print Preview document is set to the print document.[code]...
When I print the document (from print preview or my print button) the papersize/margins are different...this is how:
1. If I draw a rectangle from (0,0) to some width or height the point is in the corner of the print preview but on my actual printed page it is about 1/4 in to the right and 1/8 in down.
2. I have an extra inch or so on the right side and bottom of the "page" that print preview will print to but will be cut off in actual printing.
I am assuming that there are some default settings (like the printer gutter and letter paper size) that print is getting from the printer that print preview is not, possibly. I need to have my print preview look exactly like my actual printed page.

I have a 3-axis robotic machine. But due to training purposes, i would like to create a simulator/emulator that act just like the 3-axis robotic machine. I want the simulator to be able to create its own virtual parallel port. So instead when i execute the coding that operates the actual 3-axis robot,whenever i send a trigger to my virtual parallel port, my simulator will start working. So my question is,
1) How to develop a simulator/emulator using Visual Basic.NET
2) How to access and create a virtual parallel port within my computer.

View 2 RepliesI'm using VB2008 and I have a CmdButton and a Listbox. When the CmdButton is clicked, it will look for all the files contained on a fixed directory and the names of the files will be enumerated to the listbox. I have that piece working perfectly.
The question is -- after the listbox is populated with the filenames, can I select one or multiple items from the listbox and copy the actual files from the original directory to a directory that the user will specify via browse folder dialog? Maybe right click on the selected item(s) then export? Just a thought..
lets say i have a string that holds "Monday" and another string that holds "9:45:00 PM". would it be possible to look at the Date.Now() function and see when the next Monday is, and then convert those two strings into a date? lets say the next monday was 05/20/2011. I would want the date variable to hold "05/20/2011 9:45:00 PM". any ideas guys?
View 1 RepliesI am converting a VB.Net application to C#. Everything else is going great. Except this bit. I have a function which builds menus,sub menus and seperators from a database. It can build a MenuStrip or a ContextMenuStrip which can then be assigned to a form.
This means that menus can be extensive and conpmex but managed outside the application, which I also use as part of my security access model. All menus are controlled from the database externally, it also means I can develop visual tools (Treeviews etc) to manage user menus. The application uses menus extensively which is by design.
Programmatically I want to assign an eventhandler to every item that isnt a dropdown or a seperator
In VB I would do this, (works perfectly)
[Code]...
"System.Windows.Forms.ToolStripItem' does not contain a definition for 'DropDownItems' and no extension method 'DropDownItems' accepting a first argument of type 'System.Windows.Forms.ToolStripItem' could be found (are you missing a using directive or an assembly reference?)"
Consider the following case:
Public Interface IHasDateUpdated
Property DateUpdated As DateTime
End Interface
Public Class MyClass
[code]....
Now, assuming I was referencing an instance of MyClass as an IHasDateUpdated; how would I determine the actual name of the property that implements the interface property via reflection?For example:
Dim x As IHasDateUpdated = New MyClass()
' How do I derive "MyDateUpdated" from "x" using x.DateUpdated?
Is there a way to make the actual tabs different sizes? I just want the tabs themselves different sizes not the whole thing. Seems like the itemsize property does this but it will only allow you to set one size. I want each tab to be a different size depending on its text.
View 11 Repliesso I was originally having problems even saving the data, but I can now get it to stay in the dataset, and when I switch to another page it stays there when I go back to it. Although when I close the form and reopen it, the changed data has not saved. I know that it is because I have only updated the dataset and not the database, so was hoping someone could give me pointers of how to approach it.

There appears to be a problem when I use the CallByName function in my actual script. While testing it I used some hardcoded arguments to pass to the procedure in CallByName function. This worked fine. In the actual script these arguments are coming from an XML file. When I read this XML document the values are string values by default:
<Parameters>
<Parameter>A string value</Parameter>

It seems that the autosize columns will only make them bigger. For example, if I have a DGV that fills most of the form and then only three small columns are loaded, there is a whole bunch of darkgrey empty space. Is there any way to snap the side of the DGV to the actual data?
View 8 RepliesI have the following barcode image:
I'm using the following iTextSharp VB.NET script to generate a PDF document containing this barcode:
Dim pdfDocument As iTextSharp.text.Document = Nothing
Dim filename As String = HttpContext.Current.Server.MapPath("barcode.pdf")
pdfDocument = New iTextSharp.text.Document()
[Code]....
When this PDF is generated, however, the image is appearing larger than expected, and is distorted:
I can't see anywhere where I'm setting the image to be a specific size, so why would it distort like this? And how can I prevent it?
It's crucial that this image remains the size it is intended to be so that it can be read by barcode scanners.
How do I determine a mapped drive's actual path?
So if I have a mapped drive on a machine called "Z" how can I using .NET determine the machine and path for the mapped folder?
The code can assume it's running on the machine with the mapped drive.
I looked at Path, Directory, FileInfo objects, but can't seem to find anything.
I also looked for existing questions, but could not find what I'm looking for.
