How to read a file and write into a text file? Ask Question. Asked 12 years, 4 months ago. Active 5 years, 11 months ago. Viewed k times.
I want to open mis file, copy all the data and write into a text file. My mis file. File name — 1. I tried this code. Improve this question. As noted earlier, this function returns a string with the actual bits in the resource. These are the values that can be used for format parameter here:.
Since we have four icons in our AboutVB. I created an application with four OptionButton components labeled Earth, Water, Air and Fire and four Click events — one for each option. The code for each OptionButton and the Form Load event — to initialize it looks like this with the Id and Caption changed accordingly for the other OptionButton Click events :. The "big deal" with custom resources is that you normally have to provide a way to process them in your program code.
The example we'll use is a fast way to load an array with a series of constant values. Remember that the resource file is included into your project, so if the values that you need to load change, you'll have to use a more traditional approach such as a sequential file that you open and read. 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 :.
