View 3 RepliesSaving Form Data Into XML Format?
Sep 20, 2010I am working on developing a program that needs to keep the data of radiobuttons, textboxes, comboboxes, etc. and it needs to be able to save several files(one for each different user). I found a quick solution from a forum, but it will only save the data from a textbox, or a tabpage. The solution that i have came up with, is to use the data, put it into a textbox, to save,then when it opens the file, it will use the data and put it back into the controls. (EX.)
If
TextBox30.Text =
"Full"
Then

This does work but it does reduce some flexibility, and takes alot more programming than what is needed. I am looking for a simple way to save the data, and retrieve it.

Determine Which String: "Input String Was Not In A Correct Format"
May 14, 2009I am receiving this error message: "Input string was not in a correct format." on my ASP.net 2.0 VB project.
When looking at other posts with this error its obvious that each time it will be specific to the users' project. Therefore my main question is, is it possible to generate a more informative error message?
I am already in debug mode but it does not tell me in which string the problem lies. I am converting some strings to integers with "Cint" and have also tried the Integer.Parse() method to no avail.

Determine If File Type Is A Bmp?
Apr 28, 2012I want to scan a directory and see what files are NOT bmp image files. As the file extension can lie I need to interrogate the file itself. I found some code here [url]...?ID=112 that does exactly this however it was written for VB5 and is 13 years out of date! I tried compiling it however VB 2010 baulked and I don't have the expertise to make it work.
View 1 RepliesDetermine If Row In File Is Date
Jun 13, 2011When scanning a data file of this kind of form:
21/02/11 11:00:23, true, false
22/02/11 02:03:43 AM, true, false
22/03/11, false, false
2011-05-21T12:30:20, true, true
The 2nd and 3rd row are not important. How can you, by scanning a file, determine if a row comprises of dates, particularly when they have inconsistent formats? In the example above, for instance:
1) 1st line is date and time
2) 2nd line is date and time but also AM/PM
3) 3rd line is only date
4) 4th line is GMT format.
I'm not requesting code, but perhaps an algorithm or some guidelines on how to achieve this.

View 1 RepliesAsp.net - Determine File Size Before Upload?
Jul 8, 2010So we're having this problem. A user goes to upload a file, and if it's above 10MB, it just kind of times out the page, and clears, and no good error is thrown to describe what happened. Ideally, we would like to examine the file size when the user chooses the file they want to upload but I don't know if this is even possible. Our framework is built with ASP.NET, VB.NET, and Javascript (and ExtJS 3.0), and it runs in IE.

View 3 RepliesDetermine If URL Exists Without Requesting The File?
Jan 25, 2010I would like to check if a URL exists -- without requesting the file. The program needs to check if a PDF or Excel spreadsheet exists at a particular URL. If it does, it might want to download the file, but it should not download it every time.
I currently use the WebBrowser.Navigate method to do this, but it always downloads the file. But I don't want to actually download the .pdf or .xls file, I just want to determine if the URL exists.

View 3 RepliesDetermine Other User Of Excel File?
May 27, 2010I am currently using the FileOpen method wrapped in a try/catch block to determine if a particular Excel file is currently in use or not.
When my app tries to access the file, I would like to be able to notify the user who it is that already has the file open. If I try to open the file in excel while it is in use, the message that Excel provides includes the network login of the user that has the file open. Is it possible to get this information via code so that I can tell the user of my app the login of whomever already has the file open?

ITextSharp Determine If A PDF File Has Fields In It ?
Oct 30, 2008I need to create a PDF drawing of our products with dimensions filled in, based on template files. After the user selects the proper template file for the desired product, a window should pop up that prompts the user for the necessary dimensions, such as width, length, etc. Then the program would fill in all the fields on the template form with the proper values. Some fields would just be filled with the exact values that the user enters in, but other fields may require a calculated value based on the entered values. ie. Overall width = nominal width + 6. So somehow I need to figure out how to make the template hold the equations. Can anyone offer me some guidance on how to make this work the way I described? Can iTextSharp determine if a PDF file has fields in it? Can it loop through all the fields & get the field names?

Jul 2, 2009I'm trying to use Adobe's command line parameters to launch a PDF file with a user's search term passed in automatically. Unfortunately, Adobe's syntax for this command requires me to start Acrobat.exe (or AcroRdr32.exe) and pass in parameters, including the PDF file name.I have users that might have any version of Adobe Acrobat from 5.0 up, or they might be using Adobe Reader version 5.0 and up. I know when I double-click a PDF file, Windows has an association with that file that points to wherever Acrobat.exe (etc...) is installed to launch the program. How can I get access to that information?I've looked in the registry at"HKEY_CLASSES_ROOT.pdf", but don't see much in there that would lead me to "c:Program FilesAdobeAcrobat 8.0Acrobat.exe" or wherever the program is installed. Does anyone know how I can access this information?
