How to get the time from a computer Stuggo13-Jul-04 4:11 Stuggo 13-Jul-04 4:11  Hi all, I'd like to know how would i be able to code an application to copy the time (copy a time stamp) from a client computers clock. Example Program: A simple windows application with a button on it, when i click the button, the client computer returns a time stamp or time strap from the computer's clock to the form "04:17pm", to a label or textbox. The source code would be very much appreciated ..! Thanx! Re: How to get the time from a computer Heath Stewart13-Jul-04 4:20 Heath Stewart 13-Jul-04 4:20  Logically, you should look at the DateTime structure in the .NET Framework SDK, which has a static property called Now. If you further look at the documentation for ToString, the solution's quite obvious: textBox1.Text = DateTime.Now.ToString("hh:mmtt");   Microsoft MVP, Visual C# My Articles Response.Redirect is not working.. a peculiar problem..One solution found !! PhaniKatakam13-Jul-04 2:07 PhaniKatakam 13-Jul-04 2:07  I would like to share a solution with all of you guys to the Response.Redirect problem. I have a scenario: 1. An asp page containing two submit type buttons 'Back' and 'Save'. 2. Save may do some action and stay in the same page.. 3. But Back would do same as save button..but Goes to Home Page. 4. U may have Save_Click () serverside code in aspx.cs 5. U can simulate the same from back.. and also hidBack to maintain from which button its coming from... <input type="image" id="Button2" style="Z-INDEX: 101; LEFT: 304px; POSITION: absolute; TOP: 136px" value="Back" OnClick="return ClickBack()"> <script language="javascript"> function ClickBack() { document.Form1.hidBack.value = "YES"; document.Form1.Button1.click(); //IMPORTANT:: RETURN FALSE TO NULLIFY POSTING BY BACK BUTTON. return false; } 6. Server side code may look as private void Save_Click(object sender, System.EventArgs e) { if(Request.Form["hidBack"] == "YES") { Page.Response.Redirect("Home.aspx",false); } Response.Write(" U pressed first Button"); } </script> 7.if WE DONT HAVE //IMPORTANT:: code line, it will postback twice to the server..there by Response.Redirect doesnt work. 8.

I got a little question about distributing a .Net C# Application. Many of you already did such things, and maybe you find the time to give me a hint on doing this I created a small C# Application and I wish to upload it so that anybody can use it. I gave it to a friend for testing but the problem is that the Application crashes when you try to run the executable. The target computer already had the .Net Framework 1.1 installed. What I sent to my friend is the executable and two DLLs. The program uses the WinSock control and the two DLLs are something like AxInteropWinSock.dll or something like this, the only difference is that one of them does not have the "Ax" in its name. This is not so important... what's important is that I sent the .exe and the two DLLs in the same folder. I took them from the "Release" folder of my .Net Solution, after I ran the solution using "Release" configuration. I saw on the Internet stuff about using MSI files to make a setup or assemblies. I don't know how to use those and the Microsoft documentation is terrible. I would prefer to give this to somebody in a zip file, without any complicated setups and stuff like that. It's a simple application, I'd rather avoid using MSI files and so on. Any help is greatly appreciated, thank you for your time and have a nice day. Axonn. The Greater Mind Balance Re: Problem when Distributing A C#.Net Application Heath Stewart13-Jul-04 3:56 Heath Stewart 13-Jul-04 3:56  MSI is not a magic bullet that will solve your problems. Obviously, something is missing. If all you use MSI for is copying those assemblies into a folder, then something as simple as COPY or XCOPY or just zipping it up will do fine. The difference between Interop.something.dll and AxInterop.something.dll is, by default, that the Interop assembly contains the typelib wrapper (RCW, or Runtime Callable Wrapper) and the AxInterop assembly contains the control(s) that extend AxHost, a Control which wraps ActiveX controls. Distributing those assemblies isn't enough, however. Since they are only wrappers, you need to distribute the WinSock COM control that you're wrapping. All those assemblies do is make the COM control and typelib useable in .NET (through the RCW). This is where MSI would be handy. COM controls need to be registered on the system and MSI can do that easily. You can add the file to the File System editor and in the file's properties (in the PropertyGrid), set the registration to SelfReg (something like that). You don't need to do this, though. If you don't plan on mass-deploying this, just direct users to download the WinSock COM control and install it it, if it has it's own installer. If you do want to distribute this to anyone, though, I'd recommend using an MSI package. VS.NET's Windows Installer projects are very simple to learn, but are by no means complete (for our installs, I use Wise for Windows Installer, which is a full-blown authoring package for MSIs and MSMs from Wise[^]). The VS.NET is simple to use and you should explore it a little. For example, in the File System editor you can add folders to whatever pre-defined folder you want, then add your project outputs (handy when you want to maintain version compatibility within a solution). Just right click in the folders and seld Add File, choose Project, browse to the project you want and select Build Ouput. Now when you build the MSI project it will make sure the other projects are up-to-date and automatically grab the build outputs (the assemblies) from the projects' target directories. Also add the COM control if the VS.NET Windows Installer project doesn't do it already (it often will). Make sure that it's set to register itself as I mentioned above.   Microsoft MVP, Visual C# My Articles Re: Problem when Distributing A C#.Net Application Axonn Echysttas13-Jul-04 5:19 Axonn Echysttas 13-Jul-04 5:19  Thank you for your answer Heath. I can see why you are a MVP . The problem is that I`m kind of new to the .Net "peripherical utilities". I've been developing programs in .Net at work for a year, but I never had to distribute one. Now I made a little IRC client at home and I want to deliver it and I have problems... Not to mention that I don't know what's that XCOPY or "File System Editor" and where I can find them. But I have MSDN and I will search, that's the least of my worries. First of all... the File System editor can help me? I can add files to my project using that, maybe, but will it register the WinSock OCX control? Can you tell me if the Windows Installer made be Wise is free? Thank you, have a nice day The Greater Mind Balance Re: Problem when Distributing A C#.Net Application Heath Stewart13-Jul-04 5:24 Heath Stewart 13-Jul-04 5:24  XCOPY is a program used to copy files and has more features than the simple COPY shell command (it's not a program, but is implemented by the command shell). The File System editor is a few of the file system in a Windows Installer package. Again, I encourage you to play around with it. It was designed to be simple (overly simple in my opinion, since I've been working with Windows Installer since MSI 1.0 beta). Wise for Windows Installer is most definitely not free (it's a commercial application; it requires lots of time and money to develop), and you can find more information about it at the link I gave you in my first reply.   Microsoft MVP, Visual C# My Articles Re: Problem when Distributing A C#.Net Application Axonn Echysttas13-Jul-04 5:49 Axonn Echysttas 13-Jul-04 5:49  Hmm... so the File System Editor is included in the Windows Installer package. Can you tell me where I can find that? MSDN is very obscure... I can't find anywhere something that says how to get to the File System Editor. (Where it is located on the hard drive or where I can find it using menus or stuff like that) Another question. Would it be enough to use regsvr32.exe to register the winsock ocx on the target machine? Thanks again The Greater Mind Balance Re: Problem when Distributing A C#.Net Application Heath Stewart13-Jul-04 6:09 Heath Stewart 13-Jul-04 6:09  It's part of the Windows Installer project package. Select your Installer project in VS.NET (after adding one, of course), and select View->Editor->File System, or click the "File System Editor" button above the Solution Explorer with your installer project selected (or something in the project). If you don't want to use an installer, yes, you can run regsvr32.exe on your WinSock OCX to register it.   Microsoft MVP, Visual C# My Articles Re: Problem when Distributing A C#.Net Application Axonn Ech.13-Jul-04 10:50 Axonn Ech. 13-Jul-04 10:50  Pfiuu , yes, this will surely work.

What I do want to do is sending information of my Windows Application (some Textboxes) via LAN or net to a server (apache and/or tomcat). My Application is written in C# in Visual Studio 2003 and the server will be implemented in JAVA. So we decided on SOAP and XML for the communication between the server and the client (= my Windows Application). So I had a look for some infos on SOAP and how to implement the main modules, but 'til now I wasn't successfull. So it would help me a lot if someone told me how to do this. Thanks. Stephan.

I do use Outlook 2000 and my aim is to drag and drop Outlook contacts into my C# application (which is a Windows application) in a Textbox. I managed the drag&drop methods but I do only want to insert the telephonenumber, lets say the business number and NOT the whole contact. I added the reference to the Outlook9 library but wasn't able to change my methods to only get the number. Does anyone of you know what I do have to change/add or what ever to make it work?

Your application needs to be able to understand the clipboard format - and there are many - so picking the right one helps. The Outlook typelib is for programmatic access to the objects used by Outlook. Very rarely do typelibs assist with parsing clipboard formats. You should download Mike Dunn's ClipSpy[^] application from this web site (there's others like it, but his is pretty nice). If you drag and drop a contact onto the application window, it will enumerate all the clipboard formats supported as well as show you the data in a hex viewer that the clipboard formats contain. Then, just use GetData("whatever clipboard format"), instead of the very limited and most basic clipboard formats in the DataFormats class (in actuality, clipboard formats are registered strings).   Microsoft MVP, Visual C# My Articles Re: problems with importing Outlook contacts Stephan Wright13-Jul-04 22:38 Stephan Wright 13-Jul-04 22:38  Well thanks for this hint! It says: RenPrivateSourceFolder RenPrivateMessages FileGroupDescriptor FileContents (grayed out) Object Descriptor CF_TEXT The telephonnumbers can only be found in the last type. Because I do only want to extract the telephone number(s) of the contacts. If there are more than one (business and mobile e.g.) that's another thing, but in general, I do only want to extract the number and leave the rest behind. So I have to use the Clipboard Format Text (like it said in Google). But well, where and how do I get to the Clipboard Format?? Maybe an example of some code will extinguish my confusion (e.g. how my example should look like, especially the type in braces!) I am familar with C/C++ but well, C# is different but somehow similar as well. So I am quit new to programming in C#, trying to port my knowledg of C/C++ and trying to understand the rest! Maybe someone of you out there could hint me to what I have to do, because in the MSDN I found nothing and everything I found about CF_Text googling the web, wasn't C#! Thanks! Stephan. Re: problems with importing Outlook contacts Heath Stewart14-Jul-04 3:13 Heath Stewart 14-Jul-04 3:13  The CF_TEXT clipboard format is the same as DataFormats.Text in the .NET BCL. Both are simply defined as "Text" (actually, CF_TEXT is a pre-registered ATOM, IIRC, defined as 1). So, as you posted before, just use dataObject.GetData(DataFormats.Text) and parse the text to get only the phone number. Because of the variability, you might consider using a string tokenizer or the System.Text.RegularExpressions.Regex class for regular expressions. FYI, C# really has nothing to do with this. Since you're new, it's important to understand that C# is one of about 30 languages currently that target the Common Language Runtime (CLR). C# has access to the same classes as any other language. The Microsoft .NET Base Class Library (BCL) is the assemblies that comprise the .NET Framework, but any assembly can be used by any language because they all compile down to the same Intermediate Language (IL) that is contained in a module which is embedded into an assembly (which may also contain assembly attributes and embedded resources, and always has a manifest of what it contains). So, the clipboard and drag-n-drop functionality is actually provided by the BCL assemblies (System.Windows.Forms.dll, specifically). While the same level of functionality is not exposed by the BCL classes, the OLE clipboard and drag-n-drop functionality is encapsulated and used (otherwise you wouldn't be able to drag-n-drop out of your .NET application). I'm currently developing a library that does expose all the functionality in a .NET-friendly manner, but it will be quite some time before it's done (I don't exactly have a lot of time).   Microsoft MVP, Visual C# My Articles SNTP Class don7cry12-Jul-04 21:46 don7cry 12-Jul-04 21:46  somebody can explain about SNTP Class? thanks Nho'c Ti` Re: SNTP Class Heath Stewart13-Jul-04 5:13 Heath Stewart 13-Jul-04 5:13  This forum is for discussions about C#, not SNTP.

Roman Rodov13-Jul-04 1:25 Roman Rodov 13-Jul-04 1:25  It is an interesting concept, but probably not so very well suited for the .NET world with its own memory manager and a garbage collector, also the word "easy" in the article name is in quotes for a purpose. You will be much more better of with an implementation of a "Command" OO design pattern, which will allow your app to support the same functionality but much more elegantly.
