Creare file res vb6

This example creates an empty text file at the specified path using the Create method in the File class. The path name is malformed. For example, it contains illegal characters or is only white space ArgumentException. The path is read-only IOException. The path name is Nothing ArgumentNullException. CopyMemory copies block of memory to a different block of memory without regard to the data type that is stored there.

This technique is well known to VB 6'ers as an ultra fast way to copy data inside a program. This program is a bit more involved because first we have to create the a resource file containing a series of long values. I simply assigned values to an array:. Then the values can be written to a file called MyLongs. It's a good idea to remember that the resource file doesn't change unless you delete the old one and add a new one. So, using this technique, you would have to update the program to change the values.

To include the file MyLongs. Then select the MyLongs. You also have to change the "Type" of the resource by right clicking that resource, selecting "Properties", and changing the Type to "longs". Note that this is the file type of your MyLongs. Then read the resource file:. Next, move the data from the bytes array to an array of long values. Allocate an array for the longs values using the integer value of the length of the string of bytes divided by 4 that is, 4 bytes per long :.

Now, this may seem like a whole lot of trouble when you could just initialize the array in the Form Load event, but it does demonstrate how to use a custom resource. If you had a large set of constants that you needed to initialize the array with, it would run faster than any other method I can think of and you wouldn't have to have a separate file included with your application to do it.
