If you want to print a barcode, use font. Lots of results: http://www.google.com/search?hl=en&q=barcode+font&meta=&aq=0s&oq=bar+code+fo[^]

Depending on your requirements you merely use a font. You can download a code 39 (3 of 9) font for free online which can hadle uppercase letters and numbers. Certain barcodes are limited to the characters they can handle and the more you use the longer the barcode becomes (which is true for code 39). I have found the most useful barcode to use is a code 128 type. These barcodes are a fixed length (regarless of the amount of characters) and also use all of the 128 ASCII characters . Code 128 barcode fonts require a checksum (validity check) in order to read characters so they are more challenging to use but if space is limited on the items you wish to apply barcodes to, I would recommend purchasing a code 128 barcode font and checking articles online that can help explain how to create this checksum. Good luck

NumericUpDown object question.

I'm a vb.net newbie; I'm currently developing an application for windows mobile on VB.

The program runs a math calculation every time a button is pressed.
I have a NumericUpDown box, is it possible to have the button be pressed automatically every time the value is changed on the NumericUpDown box?

I have heard of button1.performClick() but I have no idea how to use it.
Also I've noticed that the NumericUpDown object has a "ValueChanged" declaration.

Thank you

Any help would be greatly appreciated. Smile | :)

on valuechanged event of numericUpDown use following code

Private Sub NumericUpDown1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NumericUpDown1.ValueChanged<br />
call button1_click(nothing,nothing)<br />
'or<br />
button1.PerformClick()<br />
    End Sub

hope this helps

Why are you clicking the button?? Why not just handle the ValueChanged event of the UpDown control and call the code that does your calculation from there??

Hi All,

I want some information regarding Windows Vs VB. For Ex. if I want examples which work with VB 6.0 to handle desktop functions. can anybody have some info please provide me.

Thanks in advance.

VB6 is a dead language and examples are becomming more and more scarce. I highly suggest moving to VB.NET. As for examples, you're going to have to be a lot more specific in what you want to do with "desktop functions". At this time, the only thing we can do is direct you to Google and start searching for examples.

We're not going to write your code for you. YOU have to write the code and when you get stuck with a specific problem, then we'll help.

At this time, the only thing we can help you with is tell you to go to Google and start searching for examples, probably using search terms like "c# image zoom", or go to Rent-A-Coder to pay someone to write your code for you.

This is so trivial that if you don't have the resources to learn how to do it, it means you probably have no VB books, which is probably why you have no idea how to do this and seem to think that telling us your laziness is 'urgent' is the way to resolve the issue.

Before doing a SaveAs, convert to the Opposite of "Read Only" (Write Enable)

Probably simple for most in here but I am trying to find how to convert an xls file (Excel) from "Read Only" to it's opposite. Here is the code I have:

xlsBookTs = xlsApp.Workbooks.Open("F:\filename.xls")
ExcelTsOpen = True
xlsSheetTs = xlsBookTs.Worksheets(1)
xlsBookTs.(((NEED HELP HERE)))
xlsBookTs.SaveAs("F:\filename\ts" & Format(Me.MonthCalendar1.SelectionStart, "yyyyMMdd") & ".xls")
ExcelTsSaved = True

Basically it loads the default file ("F:\filename.xls") and saves it with the date but needs to be in an adjustable format when it Saves As.

Many thanks in advance to those who offer usable advice.

Why is the workbook read only?

If it's protected, you can call Unprotect, if the file has readonly-flag, you can remove it, although I think that if you save it using SaveAs, the readonly flag won't be set to the new file (not sure though).

Sadly the new file saves as a Read Only. The initial default file is read only to protect it.

Is the file read only, or is it protected (using excel) and therefore read only? Also check that the saved file isn't open in your app (that you call close on the workbook).

The file loaded is read only, not Excel protected. I need to save it as another name (easy) but remove the "read only" setting (hard part) in code.

Once an Excel file is opened "ReadOnly", that's it. You can't change that unless you close the file and reopen it with full access. Your only option is to save the workbook to another file using SaveAs.

I am trying to save it with a Save As, only the Save As is also saving it as read only. I need to use code to disable the Read Only in the converted file at Save(SaveAs) time.

The file cannot be saved as ReadOnly. Only when you open the file does this come into effect. Possibly your code still has the file open after it's saved??

Hi dave. I realize the read only cannot be saved.

The file loaded is read only (not Excel protected). I need to save it as another name (easy) but remove the "read only" setting (hard part) in code.

For some reason, the new file, although saving under the new name as I have wished also carries the "Read Only" setting from the original file that was copied.

I need to change that during the "Save As" part so as to remove the "Read Only" setting on the newly named and saved (SaveAs) file.

It needs to be done in code also, not via manual access from the windows explorer.

Thanks for your time and efforts so far Dave.

Last time: THERE IS NO READONLY SETTING! The file is only determined to be "ReadOnly" when it is loaded by Excel. If the file is already open by another process, or another instance of Excel, the file will be opened as "ReadOnly". THERE IS NO SETTING IN THE FILE THAT DOES THIS.

If the file was just saved as a new filename, but you haven't closed it in your code's instance of Excel, ANY ATTEMPT TO OPEN IT IN ANOTHER INSTANCE OF EXCEL WILL RESULT IN IT BEING "READONLY".
