File Filter On More Than ONE File Type?
Aug 2, 2010
I am trying to make a file/drive/folder directory interface with VB. It is all working except the only thing i can't manage to make it do is to filter on more than one file type. I want to be able to filter on BMP and TIF files, i have the following code:
filterList.AddItem "*.TIF; *.BMP"
filterList.SelText = filterList.List(0)
'Apply the file type choosen to the file list displayed
filDialog.Pattern = filterList.Text
The filterList is the list box with the file type extensions and the filDialog is the list box with the files.It only filters on the first file type, so in this case TIF (no BMP), even if you swap them it only filters on the first file type.

how to set up the filter property to look for more than one file type? msdn says we can set the filter to '*.*' or *.txt' etc, but doesn't say how to specify more than one type.I've tried a pipe delimited string but it didn't seem to work e,g '*.txt |*.log|*.xml'.

I made a program which uses a filesystemwatcher component, but it seems to record absolutely EVERY change made, and I want to set it to ignore some file types. How can I set the filter to ignore certain types? For example, .LOG files. I don't want it telling me that that file updates, cause it does it every second practically.

I need to create a dotNet saveAs dialog, but I need to populate the file formats in the dialog. After the person have selected a file, it must connect that to a file format that I populate into the SaveAs command in the Excel Interop. After the Interop SaveAs command, I must check if the file have been saved correctly.

I would like to restrict what they see in the file upload dialog, which is set to "All Files" by default. I understand how to validate that they only uploaded a certain file type, that is not the question here. I would just like to know how to default the file type in the file selection dialog.
Is there any way to change this to "PNG only" or "*.png"?
This is using AsyncFileUpload in the ASP.NET AJAX Control Toolkit.

I'm trying to read in a file. I'm not even sure what kind of data the file contains. Is it binary, unicode, etc? Or maybe it is encryted? I doubt it is encrypted, but I really have no clue. I am pretty sure it contains geometric/drawing data. It shows most characters as boxes.I've attached a picture of the contents when I open it in wordpad. Does anyone have a clue what type this is? and how to get it into a readable format using vb.net?

I want to change the log file filtering at filtering at runtime. I am referring to the traceEventType in the following example.
My.Application.Log.WriteEntry(String.Format("{0:T} DeserilizeProperties", Now), _
TraceEventType.Verbose)
I have found the documentation that allows me to change it in the config file, but I need to do it at runtime. What I am trying to acheive is to allow a beta tester to turn on more detailed logging (according to the TraceEventType...) when encountering an issue in order to email me the log. And then switch back to less detail.TraceEventType.Information)
.Application.Log.WriteEntry(String.Format("{0:T} Send email", Now), TraceEventType.Information)

I am searching through files and only want to include files with certain extensions. Right now I have what is below but it would be stupid to do it that way for 3 or more file types and it isn't completely case insensitive.
If ext = ".jpg" Or ext = ".JPG" Then
I want to check for .jpg .gif .png all case insensitive.

I have a problem to implement action button to execute bat file . I am using SharpDevelop Version : 3.2.0.5698 . this code looks like :
Sub Button3Click(sender As Object, e As EventArgs)
Shell(Environ$("CONFIG") & "wpis_v3.bat")' TODO: Implement Button3Click
End Sub
in wpis_v3.bat I have :
@echo off
%DIR%instatus.bat >> %DRIVE%users
eport.txt
status.bat launches script to check license availbilty on the server and write it to report.txt ... by launching just wpis_v3.bat it works . report is generated with all information about licenses . But when I launch from VB icon - report file is generate but is total empty . I observed that with any bat which contains >> VB doesn't write into file. Is there other way to acchive it ? I would like that VB will show only specific lines from this report.txt - which contain string : "Site" and other "Client" .

Bit of a long shot but does anyone know if it is possible (I said possible, not easy ) to create a file system mini filter driver in .NET? I'm assuming not but I don't really know of any technical reason why... just that every single example on the interwebs is C++.
I realise it would take me a very long time just to convert all of the functions and structures required to .NET before I even got started on the actual functionality of the filter driver itself but theoretically is it possible?

When I look at a file on my hard disk, e.g. test.csv, when I look at the Properties of the file, it is officially known as, "Microsoft Office Excel Comma Separated Values File", and file types of .pdf are listed as "Adobe Acrobat Document", etc. etc. All of this information can be seen in Windows Explorer too when my folders are displayed by Details. How do you get at this "type of file" information with .NET?

I would like to write a generic function that would search a List(Of T) for all elements of type TFilter and return a List(Of TFilter) which comprises those elements.
I've tried this:
Public Function FilterList(Of T, TFilter)(ByVal ListToFilter As List(Of T)) As List(Of TFilter)
Return ListToFilter.FindAll(Function(z) z.GetType.Equals(GetType(TFilter))).ConvertAll(New Converter(Of T, TFilter)(Function(z) CType(z, TFilter)))
End Function
But, it gives the following error:
Value of type 'T' cannot be converted to 'TFilter'.

Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?

OK I have a base query that is returning a list (ObjectQuery, actually but I don't think it matters) I have about 5 subtypes based on the main type and I need to filter them. Everything works fine until I want the results to be of the main type (not a subclass) Basically I have a query that includes everything, then I filter out the types that are not checked in a checkedbox list. (asp.net) Lets say I have an Entity named Task, and SubTask1 and SubTask2 that inherit from Task

I have a VB.NET program with a SaveFileDialog control with the filter set as ".asx|*.asx|.m3u|*.m3u" (without the quotes). It works fine to save a file, but if I then try to save a file with the same name of an existing file and then change the extension in the save as type box, it still thinks I want to save the file as the existing file and asks to overwrite the file, disregarding the newly selected file extension.
I have tried setting the SaveFileDialog.FileName = Nothing after saving a file, so the Save File Dialog Box the File name box is empty, but then I like to click the existing file to get the file name I want, then select a new extension and try to save, but it still asks to overwrite the file with the other extension.
I hope my situation is clear and sorry if it has been already asked a million times...but can anyone point me in the right direction or tell me how I can save the file with the currently selected extension, not the previous selected extension when the file name was entered?
Code:
If SaveFileDialog.ShowDialog = Windows.Forms.DialogResult.OK Then
If Path.GetExtension(SaveFileDialog.FileName) = ".asx" Then
' Code Here to Prepare the CodeASX ...

I would like to query an Employee by matching First and Last name. Ideally, I'd like to be able to specify that in one EmployeeQueryRq QBFC object.
I think I have a start:
Dim EmployeeQueryRq As IEmployeeQuery
EmployeeQueryRq = requestMsgSet.AppendEmployeeQueryRq()
EmployeeQueryRq.ORListQuery.ListFilter.ORNameFilter.NameFilter.MatchCriterion.SetValue(ENMatchCriterion.mcContains)
EmployeeQueryRq.ORListQuery.ListFilter.ORNameFilter.NameFilter.Name.SetValue(LastName)
Is there any way I can add an additional NameFilter to the same request? Or am I stuck walking a response list for the other criteria (albeit a smaller one limited to containing at least one value)?

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.
