Purpose: to cover the use of Tcl under the variations of [Microsoft Windows] that continues to grow at an alarming rate. Why is the growth in use of Tcl on these platforms alarming? ''A more likely interpretation of that sentence is that it is the growth of variations of [Microsoft Windows] that is alarming.'' ---- [Iain B. Findleton] ( Jan 2002 ) wrote an article on comp.lang.tcl about his experiences with Tcl on Windows.

Note that this version is different than the one posted to comp.lang.tcl - there has been some problems trying to get the autoposting software version updated :-( ... See [Microsoft Windows and Tk] for information about the graphical extension and Windows. Also, the [Tcl Developer Xchange] hosts a surprisingly (well, it surprises [CL]) active Web forum on Win* issues [http://resource.tcl.tk/bboard/q-and-a.tcl?topic_id=31&topic=wintcl%20%2d%20Windows%20issues%20and%20extensions] Other info will be added as people encounter it. For instance, Tcl runs on Windows 95/98/Windows NT, Windows 2000, and soon [Windows/CE]. ---- A frequent problem in DOS/Windows vs. C/Tcl is the use of backslashes as path separators. Tcl parses c:\test to have a Tab (\t) as third character, with "est" following that. Since strings may get parsed several times, the safest is to use slashes internally. You can get that canonical form from a backslashed pathname with set canonicalpathname [file join $backslashedpathname] Going back to backslashes may be necessary for [exec]: set backslashedpathname [file nativename $canonicalpathname];#RS ---- How can one tell whether a given application is already running under Windows (e.g. is 'internet explorer' already running?), if it is running, how can one simply switch to it (without opening a new browser window or anything)? ---- On Windows I have a third party application (the dvi previewer Yap.exe) which can tell another application to go to a particular file and source line. Unfortunately it can't use dde (at least not directly) but can only execute a command line, so it wants to do something like this (it lets you design the command line): app.exe open %f -line %l where '%f' will be substitued by the file, and %l by the line. Now, I have a Tcl/Tk application already running, which wants that information. How can I get it to my application in the easiest way?? [RS] In [Inventory of IPC methods], I have sketched a proc '''fsignal''' which uses a file in a well-known directory. You could write a little script that calls fsignal send Open [list $filename $lineno] and your "receiving app" could, when idle, call foreach {filename lineno} [fsignal wait Open] break ---- A recent question and answer from comp.lang.tcl asks: ''What options are available for printing from a TCL (not TK) script running under Windows (NT/9x/2000)?'' (See also [Printing a canvas under Windows].) One way is to just open and write directly to a device like LPT1. set pr [open lpt1 w] If the printer isn't attached to the local PC, you will need to capture the device to the network queue. One way to do this is with a command-line like: net use lpt1 \\server\printer /persistent:yes ---- A topic that's sure to come up more and more often is "[What WinForms has to do with Tcl]". ---- A frequent, sometimes implicit, topic is "[How Tcl accesses the Win32 API]". Also important for getting the right Windows feel is to "[Register file types under Windows]". ---- See also: * [windows icons] * [Windows binary resources] * [Reading version information from Win32 executables] * [Building Tcl DLL's for Windows] * [Combining GUI applications developed with Tk and 'native' Windows toolkits] * [Consio] library for accessing Windows console functions * [Embedding Windows applications in Tk frames] * [Expect for Windows] * [Generating PDF on Windows] * [How to ensure my Windows or MacOS Tk process has a console] * [Integrating Tcl and Emacs on Windows] * [Parallel port] control on Win9x/NT/2k/XP, see also [LED display driven by the parallel port under tcl control] * [Playing with Windows file associations] * [Reading Portable Executable headers] * [Reading version information from Win32 executables] * [Robust environment variables on Windows] * [SDX under Windows] * [serial ports on Windows] * [Services under Microsoft Windows NT], * [Symbolic links in Windows/CE] * [Techniques for 'driving' Windows applications] * [Tk widgets look fine under Windows] * [TWAPI] - Tcl Windows API extension * [Using Kill on Windows 98] * [Using Windows Controls in Tk Windows] * [What WinForms has to do with Tcl] * [win32] * [winapi] - Another Windows API extension at a lower level * [wince] * [winChooseDirectory] * [Windows file finder] * [Windows Helper Utilities] * [Windows Registry Browser] * [Windows shell links] * [Windows Speed Cleaning] * [Windows Start menu] * [Windows wish console] * [Windows: getting desktop properties] * [winico] * [wintclsend] * [winutils] * [winutil] * [WippleWobble - A Mini Web Browser (for Windows)] ---- '''Display control panel''': ''[Bob Techentin] wrote in [the comp.lang.tcl newsgroup]:'' According to knowledge base article "Q192806 How to Run Control Panel Tools by Typing a Command", just type "control desk.cpl" at a command prompt. You find that article at http://msdn.microsoft.com as well, if you get to the knowledge base and search for either the title or the article number. If you want to do this from C, you can look at Q232536. Works fine from ''[exec] control desk.cpl'' too, but returns an error code, so you might want to catch it. ---- [LV] 2007 July 12 For a list of some of the free code development environments on Windows, see [tcl editors] and [ide]s, If your favorite isn't listed, please update the appropriate page with your favorite tool's name, etc. ---- [LV] 2007 Oct 16 Note that there are several ways that one might use Tcl on Windows. One is natively. [ActiveState] makes [ActiveTcl] available, and there are others who also make Windows binary versions of the [tcl] and [tk] libraries, and often others as well. Another way to run Tcl applications on Windows is via an [X] window server. This mode would have the Tcl applications running on some other platform, and displaying via the X window protocol back to the Windows machine. This mode is more along the lines of an X terminal. More and more frequently, Unix developers find themselves faced with this situation. There are several tools which make this mode possible. One is the Hummingbird Exceed X Server. Another is called the Xming X window server. Cygwin used to have an X window server as well. I believe another is called X-Deep/32. There are others as well. If anyone has a link to a comparison of the various alternatives, please add it to this spot. ---- [RS] 2007-10-16: One recommended way of getting Windows binaries is [Building Tcl/Tk with Mingw], and I can recommend it too. You first install the mingw/msys development environment (just unzip one big file - gives you a [Unix]-like tool environment), then unzip the Tcl/Tk sources, configure, make, make install, and you end up with the tcl/tk libraries and executables. See the wiki page for detailed instructions. Worked well for me even on [Windows 95] with 8.5b1 (and that combination officially isn't supported any more). ---- [Category Windows] | [Windows specific Tcl commands] - [Arts and crafts of Tcl-Tk programming]
