Hi there. I am busy with making kind of script in batch.
I need to insert into it kind of "Resume" function.
I know how to write variables into a file.
But is it possbile to get it back?
Is it possible to get variables from registry?
I found a nice BAT => EXE converter. It looks really professional if you run .exe in place of .bat. I would like the user to download .exe installer of my batch program, and install the real program. But is it possible to install it (place file of program) as .exe? I don't know much about .exe languages.
If I understand your questions correctly,
Do you want to read a variable that was previously written to a file back into the batch script? Yes, it is possible to read a file into a variable as long as you know the file's format.
Yes, it is possible to read keys and values from the registry using the reg command.
Once you convert a .bat script into an .exe you can distribute it however you like. Place it in a .exe installer, zip it in a archive.

I need to dump all of my code for my project into a single text file. Is this possible in Visual Studio 2010? I haven't been able to find any options for this in VS. Is there a third party program that can do it? Every search I've done just turns up "how to print from VB", but does not address printing my actual code. Even if I have to do it module by module, that would be acceptable, but copying and pasting is a bit much.
Just FYI, I'm not talking about printing output from my program. I'm talking about printing the program itself.
Thanks.
This can be done outside of visual studio. Start a command prompt, cd to your project directory and:
type *.vb >filecontent.txt
If you have multiple project folders, you'll need to do this for each one as the type command doesn't have a /s subfolder type of parameter.
Alternatively, you could create a batch file that changes to each folder and performs the type command to output the file contents.
I know i can use 7z or winrar but i want to learn this for myself.
How would i implement a self extracting archive? I can use C# or C++ but let me run down the problem.
When i open the exe i need some kind of GUI asking where to extract the files. Once the user says ok I should obviously extract them. I implemented a simple example in C# winforms already BUT my problem is HOW do i get the filenames and binary of the files into an exe?
One upon a time i ask Is it safe to add extra data to end of exe? and the answer suggested if i just add data to the end of the exe it may be picked up by a virus scanner. Now its pretty easy to write the length of the archive as the last 4bytes and just append the data to my generic exe and i do believe my process can read my own exe so this could work. But it feels hacky and i rather not have people accuse me of writing virus just because i am using this technique. Whats the proper way to implement this?
Note: I checked the self-extracting tag and many of the question is how to manipulate self extracting and not how to implement. Except this one which is asking something else Self-extracting self-checking executable
-edit- I made two self extracting with 7z and compared them. It looks like... well it IS the 7z.sfx file but with a regular 7z archive appended. So... there is nothing wrong with doing this? Is there a better way? I'm targeting windows and can use the C# compiler to help but i don't know how much extra work or how difficult it may be programmatically and maybe adding data to end of exe isnt bad?
It is possible. I used the following technique once, when we needed to distribute updates for the application, but the computers were configured so that the end user had no permissions to change application files. The update was supposed to log on to administrator account and update required files (so we came across identical problem: how to distribute many files as a single executable).
The solution were file resources in C#. All you need to do is:
Create a resource file in your C# project (file ending with .resx).
Add new resource of type "file". You can easily add existing files as byte[] resources.
In program you can simply extract resource as file:
System.IO.FileStream file = new System.IO.FileStream("C:\\PathToFile",
System.IO.FileMode.OpenOrCreate);
System.IO.BinaryWriter writer = new System.IO.BinaryWriter(file);
writer.Write(UpdateApplication.Data.DataValue, 0, UpdateApplication.Data.DataValue.Length);
(Here UpdateApplication.Data denotes binary resource).
Our solution lacked compression, but I believe this is easily achieved with libraries such as C#ZipLib.
I hope this solution is virus-scanner-safe, as this method creates complete, valid executable file.
I have a DCL script on VMS which calls a perl script. Is there a VMS/DCL command I can use that will tell me every file handle opened by the perl script?
Set default to the disk the app runs from (or you might have to try each disk in succession if it's a really large or distributed app). Then the command is
show device/files/nosystem
If you're on a more recent version of VMS and the lists are too long, you can pipe it with a search by doing this:
pipe show device/files/nosystem | search sys$input (name of perl script)
You need to find the documentation for undocumented VMS features :-)
Seriously I think that set watch might do what you want. If you issue
$ set watch file/class=(all,nodump)
$ perl yourperlscript.pl
You will get loads of output that will hopefully include what you want. I havent done it for years, you probably tune the options to fine tune it. See

Jason, I need more clarification for a). Are you saying that you want to run your perl script in a batch file and have the batch file monitor the files being accessed by the perl script? Or something else?
Hmm, not sure about that. Maybe add a linux tag to your post so that some linux people can see this and chime in. I'm not sure why your perl program wouldn't know what files it opened. It's your program, wouldn't it access the files you told it to access? Or if you're computing the filenames somehow (which I've done in cobol, but still know at least which directory to find them in, and what naming scheme they use), you'd still have clues like what I mention. Also, since it's your program, and if you're computing the filenames, coudn't you also make your Perl program output it's own little report of what the files were? Like, just after it computes the filename, have it copy the name string to a separate report file.
How would one go about associating a file type with his application? I know how to read the command line arguments but I am not sure how I can "register" the file extension with Windows. Furthermore, my application is a stand-alone executable, so how would I keep Windows up-to-date on the location of my program?
I did a fair amount of searching and all I could find were old articles that didn't explain everything. How can I create file associations to a stand-alone executable in VB.NET?
Everything is handled by the registry. If you want to make your program self-register it's current location when run see this example.

There are many programs out there that will allow you to pack a few files together and generate an executable that has the necessary code to extract them. Somehow, those files are residing inside the executable. I am interested in doing the same thing; how is this done?
FYI, I'm interested primarily in Windows .exe files, if it makes a difference.
Look at this: Article
You could probably save a file/files in a resource, compile it into the exe then use some code in the exe to extract it out to a file.
ie:
http://www.codeproject.com/KB/winsdk/binaryresources.aspx
Self extracting .exe files are usually archive files (zip, rar, tar, etc) concatenated together with a small program that does the extraction then executes the program that was extracted from the archive.
A really sophisticated one could extract the archive into memory and then jump to the extracted code and run it, but back in the old days, that sort of thing was easier to do.
If you wanted to write your own in Windows, you would create a small console application that did the extraction, and you would include the 'real' program in the console programs' resources.
There are also products like pkzip and winzip which do it for you. If your time is worth anything, those would be more efficient.
UPX is a well known packer for Windows .EXE which can be found here on WikiPedia. And here is the main site on sourceforge for UPX.
Hope this helps,
Best regards,
Tom.
