What I'm trying to do is store a query string in a table cell. So I figured the best way would be to convert the query string to some binary format for storing and then when I pull it out of the database I would convert it back to a string of text.

I was given a school project in which I have to make a program that converts numbers between binary,decimal,octal and hexadecimal systems. I have figured out how to make a function to convert binary number to decimal number [code]With this code,a user can enter a number that isn't binary,and program will calculate it. How can I make that program doesn't calculate those numbers or doesn't accept anything else than 0 or 1? This is needed for other cases like octal and hexadecimal system.
View 3 RepliesIs there a way to convert byte values to binary so i can read the values from the bits themselves? I have some byte whose values are 00 09 and I'd like to convert the values to bits to be like this : 0000 0000 0000 1001. Then I'd like to read the value of first 2 bits and the remaining 14 bits separately.

Is it the riff header or the riff header contents(ID, size, Type). I need this info for a Regex string that would look something like this...

how to get the wave file information in vb.net like frequency,no of channels etc from wave file
View 3 RepliesSo, I re did my project in VB.NEt instead of C#. So, I put all the sound files in the resource files. I made a routine to play the sound file but it says that to make sure the sound file exists. Which it does because it played in the resource manager.Here's the sub routine to play the sound:
Dim sndplayer As New Media.SoundPlayer

This works fine for getting the wave file info, It just doesn't display the numSamples which I need.

I have used DirectSound to play a wave file in my application using the function CreateSoundBufferFromFile. It works perfectly.Now I want to play files from a resource dll file. I have created 1n2v32.dll file having nearly 100 small wave files named 1,2,3... I can play them using LoadLibraryEx, PlaySound & FreeLibrary.Now, I am trying to use CreateSoundBufferFromResource function from DirectSound api to play these files. I get Run-time error '432': File name or class name not found during Automation operation I used the following code to create the buffer.
Set LDSB = LDS.CreateSoundBufferFromResource(App.Path & "1n2v32.dll", "14", BufferDesc, gw)

View 3 RepliesI have a created a small application that records and plays audio. However, my application needs to save the wave file to the application data directory on the users computer.The mciSendString takes a C style string as a parameter and has to be in 8.3 format. However, my problem is I can't get it to save. And what is strange is sometime it does and sometimes it doesn't. However, most of the time it failes. However, if I save directly to the C drive it works first time everything. I have used 3 different methods that I have coded below. The error number that I get when it fails is 286."The file was not saved. Make sure your system has sufficient disk space or has an intact network connection".[code]

I've been trying to figure this out for hours now, and I've given up on trying to solve it myself. Basically what I need to do, is convert a "double octet" binary string, such as "11010011 01011101", into a byte or char type if possible.I use the following code to convert my Unicode text into binary:
Private Function ByteToStr(ByVal bt() As Byte) As String
Dim st As New StringBuilder
For Each byt As Byte In bt
[code]....
But that gives me weird results. The "Convert.FromBase64String" obviously isn't what I'm after. Any help would be great. If I can convert the "binary string" into a bytes or chars I can get it into a string.

i need to read binary file and in this file found the string and replace it with other one and save the file afterwords. I found many example to read binary, but to find and replace is for me mistery.
View 3 RepliesI need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
how I could check if a certain file is in text or binary format?I'm using VB.Net 2008 Express.
