You can choose what option will be more useful to you, download file via vbscript, and this post is here to clarify it. Downloading files is something really basic today, because it is really hard to find someone that does not have internet access, download file via vbscript.
You may want to do an automatic update for your program, or to make download of a file only if a user need a specific function from your code, decreasing download download file via vbscript you script. The COM technology allows another program access resources from another program. It is a Microsoft Technology and a really useful one. We can access Active Directory with it and add users and groups without opening the Management Console.
We can download and install updates automatically with Windows Update API without accessing Microsoft Update site. We can write and save a document in Microsoft Word in command line. And the better of all: It does not matter the download file via vbscript language that i am using. I download file via vbscript do that with PHP, VBScript, download file via vbscript, Javascript, C The programming language only needs to support COM access and running in a Windows environment.
Some COM functions are bult-in with Microsoft Windows, another you need to download and install it. COM functions is better because, in general, we do not need to redistribute any 3rd party code because Windows already have it. NET instead.
We need to show the command line prompt to show progress It can't be viewed on the same window from script. WinHTTP and MSXML does not need you to redistribute anything with your code, but you lost some interesting functions from WGET for Win32 it have much more functions than it!
Read WGET documentation! If you need to read the header from page or "Check local file version [ WGET support this download file via vbscript natively, but we can implement it in. NET reading header and getting Content-Length and comparing it with Local file. If you do not need to support Download file via vbscript 9x, choose the 1st one. If we do not do that, our script will return "Access is denied.
I really recommends WinHTTP, only if you do not care that your script will not run in Windows Server versions without you ask for user to change Security Settings, making the server less secure. Then, we define two strings: strLinkthat is the link that we will download, and strSaveTowhere file will be saved.
After that, we change the actual folder to the folder where we want to save the file. WGet saves the file on the actual folder that we are using, than it will save the file there. Window mode. Use download file via vbscript to hide, 1 to show in another Window. Wait for Finish. Use True to wait and only continue processing our script after finish download, False to continue processing script while download is made. But there is some cases that we can not open a second prompt.
Silent script, download file via vbscript. Download file via vbscript have an alternative: Hide prompt and show progress on the same Window. There is a problem: We lose the real-time view of our download. We have to wait download finish to show output.
We will use it to call Command Line in the next lines. It will read all lines of file until the end of file, and then exit from file. Explaining: We use InStr function to check if a string have some text. If the actual line have "Content-Length", it will get the value. We use Mid to read the string from the character 19 to the final of the string, removing "Content-Length" and maintaining only the size.
We can use it to compare the size of the actual file with the server, for example. Use -N to let WGet make this automatically. You can read another information from header data using this method, just use the right values on Mid.
WinHTTP have COM access and is a native component from Windows with SP3 and above. It means that you do not need to redistribute anything with your code if you just want to download a small file, download file via vbscript. I don't think that there is much things to explain here. You need to inform Download URL, download file via vbscript, then we get the file name from URL with Mid, it is necessary for ADODB call.
SaveToFilecall WinHTTP, download file and save it with objStream. Version 6. It is compatible with Windows XP and Serverbut requires manual installation in this OS. You can redistribute the executable and install it Recommended.
If you do not do that, it will use Version 3. Remember to warn Windows Server users that they need to change Internet Security Zone to allow scripts have internet access! It decrease security if a malicious script be executed! With this alternatives, download file via vbscript, you can download a file using VBScript. I recommend you using WGet for large files, then the user won't think that the program stopped, download file via vbscript.
If you can choose WinHTTP or MSXML, i recommend the first one, because it is more compatible even without Windows 9x support, does not require attention in Windows Server edition.
You can use X-HTTPcurl or Internet Explorer API to download files, but i didn't tested then. I do not own all knowledge of the world, and this article only was written because I want to help another people, like the people bellow does. I really recommend you read these references:.
