APP Creating PDF File With 0KB Size
Jul 13, 2010
I (SQL Server DBA) have inherited a VB App, being called in a TSQL Script, that creates a PDF using the Crystal reports. Until a month , PDF was being generated with correct extension and size, but for some unknown reason the app creates a non PDF file with Zero size. Interestingly the script that calls the App and send the PDF created as an attachment in an email via MS Outlook, sends it as PDF with data.
Also when trying to open up the same 0KB file in Acrobat, gives an error:
"Could not open because it is either not a supported file type or the file has been damaged (for example it was sent as an email attachment and wasn't correctly decoded)"
FYI, the Exchange server was upgraded so the email isn't working either and its causing a great pain for management to not to be able to have that report.

I am creating a List(Of String), always of size 9.This list contains True/False values. I need to go through this list and find the 3 values that are True (will never be more than 3, but could be less) and then set 3 string values in my code to the 3 index's of those values + 1.
Here is my current code:
Private Sub SetDenialReasons(ByVal LoanData As DataRow)
Dim reasons As New List(Of String)
With reasons
[code]...
I had 3 True's next to each other in the array and the code failed with an exception saying count must be positive or something.Now if there are less than 3 True's, it should set the remaining DenialReason's that haven't been set yet as blank (however they are set as blank in the constructor already to account for this).

being used to PHP and the easiness of creating arrays with no specific size... I'm hating arrays in VB.
Is there a way I can create an array who's size I won't know?
I'm pulling information out of an XML file and need the information available in another sub - so I'm stashing it in a public array I create at the beginning of the form.

Now all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

Alright here's my situation: I have a form. This is a very small form that can be moved with the mouse (formborderstyle=none). The transparencyKey is 0,0,1. The form back color is 0,0,1. There is a label on the form. I drag files to this label(its backcolor is black[0,0,0]). What I want is for the filesize to be checked. I already have the uploading to ftpcode, I just want to know if the file is above my limit I set. (250mb per file)

I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

Language: vb.net
File size: 1GB, and stuff.
Encoding of the text file: UTF8 (so each character is represented by different numbers of bytes).
Collation: UnicodeCI (when several characters are essentially the same, the most popular version will be the one unique.). I think I know how to handle t his one.
Because each character is represented by different numbers of bytes and each line has different numbers of characters, the number of bytes in each line also vary.
I suppose we have to compute hash for each line. We also need to store buffers location where the line each. Then we have to compare buffers. Then we will check whether the same line shows up or not.

I was using the following code to check the file size of a data file on my local machine. Now the data files have been moved to a mapped network drive and this code no longer works. What do I need to change or how do I access file size on a mapped drive?
Dim MyFile As New FileInfo(MyFilePath)
Dim FileSize As Long = MyFile.Length

I'm working on a school project right now and I have everything fine except this one part of the project: "The audit and errorevent logs should be archived if they are larger than 5K and up you need to keep up to 3 copies of the files." I know how to read and write text files just fine, so I don't need help with that. What I don't know is how to archive a file based on file size, or how to keep up to 3 copies of the files?

I am trying to figure out the size of a file after compression.
By using fileInfo.Length I can get the size but that doesnt take into account compression.
I have tried the Api GetFileSizeEx but it always returns zero so maybe I didnt do ti corectly...
