Is there a way to get the program that is locking a file, in vb 2005?

I'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?
View 4 RepliesI need to process a text file created by a Streamwriter. I have the Streamwriter object but the file location is determined by the user. The problem is, I need to process *the file* not the contents-so I need the location.
Steamwriter doesn't seem to have a Location or File property. Or am I just missing it? How can I tell what file a Streamwriter object is writing to?
Does anybody know of a way to determine the current name and link to the program on a computer currently as default associated with a file extension? For example, if you have a "*.jpg" file, it most likely will open in WINDOWS PICTURE GALLERY under Vista on default. If you associated another program with the "*.jpg" extension, then this file will be opened with tat program instead. "*.jpg" is here only an example!

I have a small database program that gets data from csv file, I created a function that formats the font color of textboxes based on dates and values.
CODE:
I place this in text changed event and I have a problem implementing it, because the date conversion will not take place until the data is loaded. The second part works but not the first(Date) part.
I can create a button and use its click event to format the text boxes just fine, however i wanted the text boxes to be formatted on the fly . The problem is no matter where i call the function the date conversion wont work.

They are running the exe and at times the program crashes unexpectedly and display the message: "... has encountered a problem and needs to close" I know I should have added code to handle the exception, but is there a way that I can find out which line in the program caused the error? What is generally as good way to track errors in a program after it has been released?

View 11 RepliesI am attempting to have my program select a file, create DataTables and then perform some other functions.

This was working at one time but after adding to my project I must have placed something in the wrong place inadvertantly or it has soemthing to do with adding columns,?
I am having a problem with my program that is desinged to read a 3rd party text file database. I posted previosuly about a problem inserting an item in a new row and the column was expectig a different data type. It appears that sometimes the column is being determined to be of decimal value, I dont understand why. the fields contain information such as
Col1
F123456
CLW-12321 etc....
So my column fills with
123456
12321 the letters just get chopped off
So I added MaxScanRows = 0 to my schema file and that took care of the problem
Except now several of my columns that contain Date Values are coming back
9/24/2010 00:00:00
without the setting MaxScanRows = 0
The date returned 9/24/2010
Here is the code for my schema ini file I am creating:
HTML
Dim fs As New FileStream("Schema.ini", FileMode.Create, FileAccess.Write)
Dim writer As New StreamWriter(fs)
[CODE]............
I have been trying different settings hence the dimmed out lines
Here is the code to fill the datatable:
HTML
[CODE].............
I am thinking that without the MaxScanRows = 0 setting the datatype for Col1 is being incorrectly determined
I am not sure what is happening with other columns that contain date values. Apparently If i use MaxScan Rows=0 all columns are being pulled over as string value which creates numerous problems. If I dont use maxscanrows then all columns appear to be correct except Col21 MLSNUM which is being pulled in as a decimal. Can I change that in the schema file?

I 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 RepliesWhen 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.
