View 1 RepliesIs there an easy way to copy a resource audio file to disk?
it is very easy for an image file (in two steps for clarity):
Dim a11 As Image = My.Resources.Speaker
a11.Save(Image_Path & "speaker.png")
All the examples on how to do this with an audio file seem to be very long winded and there are a lot of short audio files that I want to copy.
There must be an easier way in a few lines of code.
i have program that must connect to a database at startup, i want the program to first check if the database exists (incase the user deleted it by mistake). If it doesnt exist the program must copy one which i have as a resource, to a certain folder. I have run into a minor problem though.. How do i copy the file from resources to the folder because, the IO.File.Copy() method only allows me to put the file path.

I have a resource file that I include in my shared code library that has all of my re-usable classes in it (all the resources go into their own namespace). Now, what is the best practice regarding resources... should I include them in the same DLL, or should I have a seperate resource DLL and/or are there any benefits from seperating them out into their own file.

View 1 Repliesi want to know or it is possible to use flash (swf) files embeded in a form in vb i use vb 2008 express edition and windows vista ultimate if jes can somebody show me the code for something?
View 1 RepliesI have created a form with a tab control, and on each of the tabs I wish to play a different .swf file. I am using the Shockwave Flash Object in VB and the following code on tab 1 to play the first movie. AxShockwaveFlash1.Movie = "1. Lets Learn some notes.swf"But for some reason when I click the button to load that form, I get this errorAn error occurred creating the form. See Exception.InnerException for details. The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))This error doesnt appear when I try and navigate to the form without the Flash Object being present, so i'm guessing its this thats the problem.

(Visual Studio 2005, i.e. .NET 2.0)
Deleting a file is one of the controversial matters of computing. When a user deletes a file (removing it also from the Recycle Bin), they assume that the file is indeed deleted. However, what happens is that only the reference to that file is deleted, so the system can no longer remember where the file is located, but the file itself is very much intact.
I am looking for a way to delete a file permanently, the way e.g. the application Wipefile would do it, by applying successive overwrites (up to 30) over the actual position of the file on the disk. There must be a way to do this through code (I just presented an example that this has indeed been done ), so I'd like to know how to do it.
I'm using XamlWriter, XML Transform (with XSLCompiledTransform), and XamlReader to create deep copies of a user control with multiple user controls and lots of inheritance.
I have it working and am using it in my Print and Print Preview logic. The problem is that it's SLOW and I need to speed it up. Currently when the user selects Print Preview it takes about three seconds for the view to display. I need to reduce this to less than one second!

I am trying to programitally download a file from a https server, that uses cookies (and hence I'm using httpwebrequest). I'm debug printing the capacity of the streams to check, but the output [raw] files look different. Have tried other encoding to no avail.
Code:
Sub downloadzip(strURL As String, strDestDir As String)
Dim request As HttpWebRequest
Dim response As HttpWebResponse
request = Net.HttpWebRequest.Create(strURL)
request.UserAgent = strUserAgent
[Code].....
So I get the right size file downloaded, but dotnetzip does not recognise it, and the files that get copied out are incomplete/invalid zips.
due to folder size limitation in Outlook/Exchange I must archive older mails on disk as *.msg files. So I am still able to search for <TEXT> in explorer.
I create the *.msg files by drag&drop a bunch of mails from the Outlook folder to the disk folder. Unfortunately the changed-at date displayed in explorer is the date of the file creation and not the sent-date as displayed in Outlook.
I know how to change the changed-at date using SetFileTime but I don't know how to extract the sent-date from the .msg file to use it.
My question is: how can I open (in VBA) a .msg file and extract the sent date of the mail?
My application uses structures that contain strings and arrays that I want to write to disk. I understand that I can create the fixed length data types in the structures by using "ReDim" and "String$", but my question is: Does VB reallocate the storage for the structure which includes these redimensioned members in-line (which would be necessary in order to write the contents to disk), or does it allocate heap and merely store a pointer in the structure?If only a pointer is provided, is there a straightforward workaround to allow me to create fixed length data types in a structure that could be written to a disk file?Or, Is there an I/O method that will handle the situation by recreating a contiguous buffer containing the structure before writing it to disk?
View 1 RepliesAfter I ran a disk-cleanup (in my case AVG PC-TuneUp), the loading of my VB.net project gave error on a missing file.Changing the build-configuration (DEBUG->RELEASE->DEBUG) would recreate the file and all is OK. But I have basic configuration-info for the build, maybe in more complex cases some important details could be lost when the file gets deleted.I would think an information as critical as that, would be placed in the project folder, or be part of one of the many files that make up the project, but not in the temp-folder.

View 1 RepliesI am using BinaryWriter class to write a binary file to disk. When I invoke the Write method, passing an unsigned short value, it writes it in little-endian format. For example:
bw.Write(0xA000);
writes the value in the binary file as 0x00 0xA0. Is there a way to make BInaryWriter use Big Endian? If not, is it possible to create a new class, inheriting BinaryWriter and overload the Write function to make it write big endian?
I have a mySQL table(IMP_SCANS) holding the file, it's name and size for every document:
scan_1 blob
description varchar
filesize int
doc_no varchar
doc_date date
I managed to insert a file to the table. Now I need to save the file to disk.
So I have the code:
Dim conn As New MySqlConnection
Dim cmd As New MySqlCommand
Dim myData As MySqlDataReader
Dim SQL As String
Dim FileSize As UInt32
Dim fs As FileStream
[CODE]............
I all works fine up to the line: myData.GetBytes(myData.GetOrdinal("scan_1"), 0, rawData, 0, filesize) Where it says "Object reference not set to an instance of an object". I cannot figure out why I receive this error.

I have a program that must copy a file to 3 locations, the local hard disk, a USB drive, and a network location. I have the file (about 70mb) loaded into a byte array. My quesion is, since I'm not actively modifying the byte array, can I impliment a form of multithreading where all 3 threads read the same byte array at the same time?
