Doing cryptographic operations in Classic Visual Basic 6 and VBA is tricky because VB6 doesn'thave unsigned types (except the Byte type).That da*n sign bit keeps messing things up. A simple operation in C likex<<=8 is not a simple matter with a Long variable in VB6.Try this experiment:

This will 'carry over' the sign bit into the high word and print:Which is not what we expect. The correct way is to append an ampersand (&) to cast it as a proper long:Likewise, migrating values from string types to bytes and words has itsdifficulties.To convert back-and-forth between String typesand Byte

How to read a binary file into 2D array. Use C# to read a binary file such as an image file into a byte. C#.NET Read Binary File Into Byte. The goal is to read a binary file in a var and post the contents to a. Enigma tv server cracked. VB and VBScript operate on a byte array. Net - Binary Files. Reader and Binary. Visual Basic Code Snippet - Convert file to byte array. This.Net Visual Basic code snippet convert external file to byte array. Converting file into byte array important to store binary file in database, send to other systems using remoting. To use this function simply provide file path to external file. C# reading binary file or byte array to EOFHere is my problem: Some binary files have. From my understanding it used to increase the memory space for the program should it later need use of it but it causes a problem for me, if I read a binary file into an array then execute it directly into memory it causes the process to crash since the extra bytes create a problem.

Jul 20, 2015 The My.Computer.FileSystem object provides the ReadAllBytes method for reading from binary files. To read from a binary file. Use the ReadAllBytes method, which returns the contents of a file as a byte array. This example reads from the file C:/Documents and Settings/selfportrait.jpg. Visual Basic Code Snippet - Convert file to byte array. This.Net Visual Basic code snippet convert external file to byte array. Converting file into byte array important to store binary file in database, send to other systems using remoting. To use this function simply provide file path to external file.

arrays, use the built-in VBAStrConv() function.This should produce the results:

Note how the StrConvfunction avoids the need to declare the size of the byte array beforehand.(Thanks to Robert Garofalo for pointing out this useful function).For more information see Using StrConv with ANSI, DBCS and Unicode charactersets.

If you want to convert to a byte array without the Unicode conversion,do this:

This will produce the result:This time, we get two bytes for each Unicode character.See Microsoft Knowledge Base Article - 187675 HOWTO: Copy a String to a Byte Array Without Unicode Conversionfor more details.

If you want the string encoded in UTF-8, seeHow to convert VBA/VB6 Unicode strings to UTF-8.

VB6/VBA Code

The functions provided here inbasConvert andbasUnsignedWordcan help you manage some of these issues in your code.Thanks to Ernie Gibbs for pointing out a subtle error in basUnsignedWord.uw_WordAdd (2008-06-25).The code in basConvert replaces the now supersededbasByteUtilswith better and faster dynamic arrays.However, the functions in basByteUtils are still useful for ASP and VBScript applications.The source code to these three files is in binaryutils.vb6.zip (9 kB).

Vb6 Array Example

Note: Users with operating systems that are set up to use full 32-bit Unicode OS or oriental CJK charactersmay need to do a global replace of Asc() and Chr() with AscW() and ChrW() in the basConvertand basByteUtils functions above. Thanksto David Wolf of Intuit Information Technology Solutions for this tip.
