Re: C# Forms/Controls Heath Stewart8-Jan-04 4:18 Heath Stewart 8-Jan-04 4:18  You mean the PaintEventArgs.ClipRectangle? The clipping region is the area that has been invalidated and needs repainting, yes. This will not affect the controls themselves, however (as you've noticed). In order to do that, you have to position the child controls. Changing this clipping region will have no affect, other than perhaps not painting all the invalidated regions. As far as it being straight zeros all the time, this doesn't seem right. Try overlapping it party with another window, or opening a dialog on your app and see if the clipping region is something else. I've done quite a bit of this and have never seen an "empty" rectangle. My other suspision is that - since the default value for numeric types of which Rectangle is made is 0, that you might have some bug in your code (no offense - just meant as another possibility). On a side note, clipping regions are often used to make non-rectangular dialogs, like Windows Media Player, RealOne, etc. Windows Layers are a better alternative but is only supported in Win2K and up and isn't as easy to program (though better in the long-run).   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Is there such a class for user specified system fonts? IE: Message Box? Menu, Selected Items, Active Title Bar, Inactive Title Bar? Window Text? Thanks, -Luther Re: C# SystemFonts Heath Stewart7-Jan-04 18:30 Heath Stewart 7-Jan-04 18:30  Control.Font uses the DEFAULT_GUI_FONT, the stock object (see GetStockObject in the PSDK) for controls, menus, etc., if available. You can get the font used specifically for menus from SystemInformation.MenuFont. As far as the caption bar fonts go, there isn't any managed way to do this.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

However, after testing this, I've realized that only one of the selected files is actually passed as a command line argument to my program. How can I find out what other files are selected so that I can open them also? Thanks, Blake Re: clicking "Open with" when multiple files are selected Kentamanos7-Jan-04 14:25 Kentamanos 7-Jan-04 14:25  Do you know of any programs that support this feature? I can't find any. I tried all sorts of applications. I'm thinking it's a limitation of the OS (shell in particular) and not something you can work around. I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Re: clicking "Open with" when multiple files are selected Anonymous7-Jan-04 20:24 Anonymous 7-Jan-04 20:24  Textpad (www.textpad.com) supports it. So do zipping utilities like winzip and winrar. Re: clicking "Open with" when multiple files are selected Kentamanos7-Jan-04 20:38 Kentamanos 7-Jan-04 20:38  At least from what I can tell on my installation, Textpad doesn't really support opening multiple files with "Open with...", it creates a new menu entry (shell) for launching it. I know Winzip and Winrar create a bunch of new shell commands as well, which is different than using "Open With...". Are you actually selecting two files, right clicking them, selecting "Open with...", and then picking Textpad as the program and having it open both? If so, my installation doesn't do that... I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Re: clicking "Open with" when multiple files are selected blakeb_18-Jan-04 11:52 blakeb_1 8-Jan-04 11:52  Yes, you're correct. I was using the menu entry instead of "Open with" and I had just assumed that Textpad would work the same way when using open with as it does with it's menu entry. But apparently not. I guess now my question would be how to make a shell entry that would work like that. Any tips on how to go about finding out what files are selected? Thanks, Blake Re: clicking "Open with" when multiple files are selected Kentamanos8-Jan-04 12:08 Kentamanos 8-Jan-04 12:08  Take a look at this article. (It's in C++ but I'm not sure if some of these things are even possible in C# without Interops. It will give you a good starting point.) I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins C# Deployment Question Larry J. Siddens7-Jan-04 9:18 Larry J. Siddens 7-Jan-04 9:18  OK, I guess I'm just stupid, but. I have a C# app that I created and want to send it to someone else. What needs to be sent along (with the .exe) so they can run it. Thanks. Larry J. Siddens Re: C# Deployment Question Mazdak7-Jan-04 9:24 Mazdak 7-Jan-04 9:24  Well, generally if that person has .NET framework installed on his/her machine it will works, but if your program has configuration,database files or using custom assemblies it should be shiped with exe file,so typically it is better to create Set up project for your projects and add your settings and file to it and ship installshield only,not only the exe file.

Re: C# Deployment Question Niels Penneman7-Jan-04 9:26 Niels Penneman 7-Jan-04 9:26  1) Create an installer for your app in VS.NET OR 2) No installer First of all, the .NET framework should be installed on the target computer. Include dotnetfx.exe it's on the component update disk / prerequisities disk of VS.NET... Next thing to do is to check te references. If all references are made to files of the .NET framework you don't have to include any more files. If you have used custom .NET dlls (in app directory if you have chosen copy local) or COM dlls (via interop) you should include these in your distribution (COM: dll AND interop dll files, interop files are in your app output dir, main dll can be anywhere) greetz *Niels Penneman* Software/Dev Site Personal Site Re: C# Deployment Question Larry J.

Siddens Re: C# Deployment Question Kentamanos7-Jan-04 10:18 Kentamanos 7-Jan-04 10:18  That's the .NET Framework installation. Take a look here. EDIT: Here's a more direct link.

I entered 6 digits without decimal and it did not catch the exception. I don't know what's wrong. Any help ? Re: Regular Expressions Kentamanos7-Jan-04 9:27 Kentamanos 7-Jan-04 9:27  In most regular expression syntaxes, "." is a symbol that means "any character". You probably need to escape the . with a backslash, like "\.". I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Re: Regular Expressions Heath Stewart7-Jan-04 9:30 Heath Stewart 7-Jan-04 9:30  ^\d{5}(\.\d{2})?$ You didn't escape ".". Without escaping, this means that it matches any character or none. For instance, to match any 5 characters, you could use .{5}.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Re: Regular Expressions Kentamanos7-Jan-04 11:08 Kentamanos 7-Jan-04 11:08  I'm pretty sure you know this and just had a brain fart while typing, but for anyone else reading this... . actually means any character except possibly "\n" depending on options you set for your regular expressions. In other words, it doesn't match "none". More details here. I, for one, do not think the problem was that the band was down.

I'm so used to typing .* for so many things I practically think of it as a single pattern element!

Re: Regular Expressions Member 8054957-Jan-04 9:58 Member 805495 7-Jan-04 9:58  I have changed my code and it works.

Is there such a thing? I believe I cannot become a better programmer until I start understanding this: how the OS I'm coding for is actually behaving/responding to this code.

Mazdak7-Jan-04 7:49 Mazdak 7-Jan-04 7:49  I don't think you can find a book for a whole of windows cause it has very very different parts,also it is not open source ,so I'm not sure you can find out exactly all parts for that. But you can get some information if you want to work on a specific field ,you can get a book specially for that part. For example you can find out a lot about securities and how windows security acts in a books that specially about this topic. Same about other field.There is no general book for general purpose I think. Mazy No sig. available now.
