Proper Way To Determine AM or PM perlmunger5-Jan-04 12:31 perlmunger 5-Jan-04 12:31  Until now, I've just gone on my merry way assuming that the only way to determine whether a time was AM or PM was either to get back a string with .ToShortDateString() and parse it out using Split, or to check to see if the Hours field in the date's TimeOfDay field was greater than 12. I haven't been happy with either answer, but haven't found a better one. What is the "proper" API way of doing this? Or is what I've mentioned all I get? -Matt ------------------------------------------ The 3 great virtues of a programmer: Laziness, Impatience, and Hubris. --Larry Wall Re: Proper Way To Determine AM or PM Heath Stewart5-Jan-04 13:44 Heath Stewart 5-Jan-04 13:44  Why not just check if DateTime.Hour >= 12?   -----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?

I recall stepping through the debugger on a recent project and I could have sworn a 1 o'clock appointment record was coming up with an hour value of 1 rather than 13, but sure enough, I just built a simple desktop app to test it again and it came up with 13 on a 1:00 pm. I had just ASSumed that there was someething I was missing to determine meridian. Oh well. Here's to assuming!! Thanks.

If anyone knows 6 or so objects, i'll have a play with them. Thanks Cata Re: Practice - Simple COM Interfaces Heath Stewart5-Jan-04 13:40 Heath Stewart 5-Jan-04 13:40  Look in the Shell Programming section of the Platform SDK. There's TONS of easy and useful interfaces in there that you can use. Other important often easy ones are like IPersistFile, IPersistStream, and other IPersist* interfaces.   -----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?

There appears to be no documentation, although I've found what appears to be the shell section in the following path: X:\Microsoft SDK\Samples\winui\Shell I've found a few examples, but there isn't much documentation. Am I in the right place? Additionaly, how do i access the windows help files associated with the SDK? Are they automaticaly linked to VS.net? Or do i have to tie them in manualy? Additionaly, .NET can't build C. I'm looking for a microsoft certified C compiler, but they don't have any listed on their site. They are either C++, or .NET. Do i even need to compile them? Or are they all already present in the windows directory? Cheers Cata Re: Practice - Simple COM Interfaces Heath Stewart6-Jan-04 2:21 Heath Stewart 6-Jan-04 2:21  Why are you looking in directories? You're supposed to be looking in the help files which - at least for the core that should include this stuff - is a required download. Click on Start->Programs->Microsoft Platform SDK Month Year and you'll see the help files. You don't need to build anything. And "certified C compiler"? You do realize that VS.NET includes the C/C++ compiler - it's the same compiler that builds mixed mode and pure .NET assemblies when the /clr switch is used. The PSDK also includes the compiler and linker in the bin directory, as is the common place for binaries in SDKs and in *nix systems. Again, though, you don't need to build anything. Just look in help for information. If you don't have all the right help files, click on the Update link in that directory and install all the relevent documentation.   -----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?

OMG! I didn't even know it was in the start menu! Heh... I'm not stupid... really... just 99% of what I do is mistakes :P So, how does .NET compile C? I mean, you don't get C Projects? Does it just compile C with C++ then? And no, I never knew Cata Re: Practice - Simple COM Interfaces Tristan Rhodes6-Jan-04 3:01 Tristan Rhodes 6-Jan-04 3:01  Ok mate, I've got it.

Peace Cata if files exist continue else exit Leon Radley5-Jan-04 11:03 Leon Radley 5-Jan-04 11:03  I'm down a little program that shows image sequences and I'm having a hard time with error handling, i have an xml settings file that i first want to load and when that has loaded and only if it has been successfull do I want the program to continue so heres the code at it's current state. but it doesn't seem to be picking up if the file really exists or not, and I usually get a nullrefrence exeption, so how's the best way to check if the file exists? private bool readXML() { bool returnValue; doc = new XmlDocument(); if(File.Exists(xmlSettings)) { doc.Load(xmlSettings); nodeReader = new XmlNodeReader(doc); nodeReader.MoveToContent(); title = nodeReader.GetAttribute("title"); name = nodeReader.GetAttribute("name"); totalframes = Convert.ToInt32(nodeReader.GetAttribute("totalframes"))-1; rotate = Convert.ToInt32(nodeReader.GetAttribute("rotate")); reverse = Convert.ToBoolean(nodeReader.GetAttribute("reverse")); autoplay = Convert.ToBoolean(nodeReader.GetAttribute("autoplay")); play_ms = Convert.ToInt32(nodeReader.GetAttribute("playms")); autoresume = Convert.ToBoolean(nodeReader.GetAttribute("autoresume")); autoresume_ms = Convert.ToInt32(nodeReader.GetAttribute("autoresumems")); if (nodeReader != null) { nodeReader.Close(); } returnValue = true; } else { // If any errors are found Exit Application DialogResult result; result = MessageBox.Show(this, "\nError: settings.xml Missing!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); if(result == DialogResult.OK) { Application.Exit(); } returnValue = false; } return returnValue; } Re: if files exist continue else exit Nick Parker5-Jan-04 12:54 Nick Parker 5-Jan-04 12:54  What does the path look like for xmlSettings? The code to check if the file exists is correct, however you need to check the path, is it absolute or relative? - Nick Parker   My Blog Re: if files exist continue else exit Leon Radley5-Jan-04 19:30 Leon Radley 5-Jan-04 19:30  It's as simple as xmlSettings = "settings.xml"; how would the path look if a wanted to place the file in a folder in the program folder? and a want to keep it relative. Re: if files exist continue else exit Nick Parker6-Jan-04 12:56 Nick Parker 6-Jan-04 12:56  Well, typically this will work (i.e.; xmlSettings = "settings.xml";), however say you want to place the file two directories above the executing file path you could simply do: @"..\..\settings.xml". I have seen an instance where when using an open file dialog can cause the selected path (even though not related to your particular file) being appended as the path infront of "settings.xml" when you call the Load(..) method. You might check into something such as Application.ExecutablePath so that you know you are always getting the absolute path to your file. - Nick Parker   My Blog Re: if files exist continue else exit Niels Penneman7-Jan-04 9:10 Niels Penneman 7-Jan-04 9:10  maybe you better get the application path first, as the working directory is not always equal to it ... something like string path = new FileInfo(Process.GetCurrentProcess().MainModule.FileName).Path greetz *Niels Penneman* Software/Dev Site Personal Site .NET & MSN Messenger 6.1 Niels Penneman5-Jan-04 10:27 Niels Penneman 5-Jan-04 10:27  Does anyone know if I can change my MSN nickname with .NET code in an existing MSN Messenger 6 session? I could do it by communicating with the server but I want to keep my Messenger session running... I have seen somebody doing it with VB5 or 6 but the guy doesn't seem to have any website or e-mail address and VBDE could not decompile the executable. I know the application does something with API functions, to open the Options dialog, change the name, close it. It's rather annoying and I want to know if any other methods exist?

Is there any way to draw someting on a panel, then draw something above it and treat those layers separately? I mean, I don't wanna redraw the first layer, when the second changes, neither the second when the first does, because it may takes quiet much time... I've searched about layers in msdn, but found nothing. Tried to set the second panel's backcolor transparent, but even in this case, it does cover the dynamic drawing on the first panel MS Visual Studio.NET 2003 C# Re: GDI Layers Heroz5-Jan-04 9:50 Heroz 5-Jan-04 9:50  "Is there any way to draw someting on a panel, then draw something above it and treat those layers separately?" Well, the panel isn't an important thing... MS Visual Studio.NET 2003 C# Re: GDI Layers Heath Stewart5-Jan-04 9:57 Heath Stewart 5-Jan-04 9:57  You don't need different controls (not layers, that's a different matter) to paint different portions. All you need to do is paint the invalidated regions which are passed to you in the PaintEventArgs of the Paint event (for code handling other controls) or the OnPaint method (for controls extending a control to override). For some things, this isn't always possible or necessary (like for a button, very little needs to be repainted so the whole thing is typically repainted). Just use the PaintEventArgs.ClipRectangle to figure out which regions you need to repaint.   -----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?

Best code for this multithreading issue? profoundwhispers5-Jan-04 6:32 profoundwhispers 5-Jan-04 6:32  Currently, I'm fetching page IDs from an XML file. I want to write code that does the following: 1- Add these IDs to an array? arraylist? some kind of list? 2- Start 5 threads that will access this list simultaneously and download a page from the internet (for example http://www.page.com?pageid=ID) provided that each page should be downloaded only once. 3- These pages are saved on disk. What happens in case of a powercut? How can I know which page did I stop at? Thank you very much. Sammy "A good friend, is like a good book: the inside is better than the cover..."
