Re: about how to use package installer yu-yu15-Jan-04 20:27 yu-yu 15-Jan-04 20:27  Dear UB, I'm sorry, I'm luck of my explanation. In my case, At first I made some applications(exe files) using C# windows projects( a exe per project(solution)). Next I made an install project using package wizard. Then I included exe files only in this project and I made one shortcut of them in Application Folder. Build this. When I installed default install path, a shortcut link exe file, but when I installed defferent install path, a shortcut didn't link exe file. Now I am looking for some solution. Best Regards, yu-yu Re: about how to use package installer UB16-Jan-04 4:54 UB 16-Jan-04 4:54  Sorry for being such an idiot. It's not your fault, it's my fault that I couldn't understand your problem. So here goes. I just tried it your way, I added two exe files, and created shortcuts for both of them and installed to default path, and to a custom path, but I wasn't having any problem, the two shortcuts worked just fine, for both ways. (I also checked - the shortcuts were linked to the correct path/file) If it is possible here's a suggestion. Try to get all your projects under one solution, then to that same solution add another setup project, then instead of adding files to Application Folder add project output of each project. If you are still having problems post your message to a new thread, I'm sure some one else will give you a good solution. Good Luck!

This is a function in Dll. My installer called a dll. This dll have some functions. One of them is the deleting installed files. I used a dll except for a function deleting installed files, so I could run application both install default path and custome path. thank you for your advices, best regards, yu-yu Re: about how to use package installer UB19-Jan-04 5:39 UB 19-Jan-04 5:39  Hi yu-yu You are most welcome.

Does the .NET Framework have any provisions for Single precision mathematics? I notice all the methods in the Math class take Double precision floating points, and I would like to keep my application pretty speedy, as it uses a large amount of these methods hundreds of times a second. I just don't need double precision math. Thanks in advance. -- Rob Hutchinson How to specify an Assembly reference? Chris Meech8-Jan-04 5:16 Chris Meech 8-Jan-04 5:16  The following line of C# code using System.Data.OracleClient; generates the following error. error CS0234: The type or namespace name 'OracleClient' does not exist in the class or namespace 'System.Data' (are you missing an assembly reference?) I'm pretty sure that the resolution is to specify an assembly reference, but reference to what and how do you do that? Thanks. Incidentally I'm using version 1.1 of the .NET Framework, so the namespace 'OracleClient' is supposed to be there. This begs a bigger question of why do some libraries require an assembly reference and others don't and how is a developer supposed to recognise this difference?

Marc Clifton Re: How to specify an Assembly reference? Chris Meech8-Jan-04 5:50 Chris Meech 8-Jan-04 5:50  After about 1/2 hour digging through the SDK documentation, I've got my answer. In order to use the namespace System.Data.OracleClient, I must compile with a reference to the assembly that implements the namespace. This assembly is noted on the documentation for all of the classes implemented in the namespace. The assembly reference is provided as a compile time command line option as follows csc whatever.cs /reference:System.Data.Oracleclient.dll Chris Meech It's much easier to get rich telling people what they want to hear.

How Windows works... profoundwhispers7-Jan-04 7:39 profoundwhispers 7-Jan-04 7:39  I need a book/document/article/website that could detail (regardless of the programming language, if required for examples) how the Windows operating system exactly works internally. 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. Sammy "A good friend, is like a good book: the inside is better than the cover..." Re: How Windows works... Colin Angus Mackay10-Jan-04 16:59 Colin Angus Mackay 10-Jan-04 16:59  I don't think that is necessary. If you don't know how an operating system works then a book that describes in general the workings and functions of an operating system will do. If you are writing code that will interact with the operating system at a low level then a more specialised book will become necessary (e.g. if you are going to write hardware drivers). However, if all you are going to do is write business applications then knowing how to deal with SQL Server will be much more useful. As a bit of personal history... When I started writing software after a while I came to a similar conclusion, however I have never found out "how the Windows operating system exactly works internally" - I doubt anyone really knows as it took several million man-hours to create - but what did make the difference was sometime after leaving University I was introduced to the concept of patterns. I read about them and came to realise that I was already using some of them without knowing, but I found more that I had never used or considered before and a whole new world opened up. I think the question you need to ask yourself is: What sort of software do I want to write? or What sort of software does my employer want me to write? And from the answer you can work out what you need to know to do that effectively. For example, above I mentioned that learning about SQL Server would serve you better in a business application world. Also learning about DirectX would serve you better if you are going to write games. --Colin Mackay-- EuroCPian Spring 2004 Get Together[^] search trough a TreeView for a TreeNode with matching tag Kalthoff7-Jan-04 5:39 Kalthoff 7-Jan-04 5:39  I want to search trough a TreeView for a node with matching tag.

( Dialog Issues in .NET CF PocketPC 2003 Cowwolfe6-Jan-04 2:48 Cowwolfe 6-Jan-04 2:48  I'm writing applications for the PocketPC 2003 using C# and .NET Compact Framework. One problem I encounter is when I use the Dialog.ShowDialog() command I end up with what appears to be two instances of my application. And of course if the user opens up a second dialog from the first one, now there appears to be three instances of my application. Where I see these instances is under Memory | Settings | Running Programs. Of course, if you select the wrong instance, you end up bring the wrong dialog in to focus and cannot do anything (because another dialog has the focus). Does anyone know how to get around this problem? Am I using the wrong command, "Dialog.ShowDialog()"???

In the main.cs I have: [STAThread] static void Main() { System.Threading.Thread.CurrentThread.ApartmentState = System.Threading.ApartmentState.STA; AWSWndExceptionHandler eh = new AWSWndExceptionHandler(); Application.ThreadException += new ThreadExceptionEventHandler(eh.OnHandleException); Application.Run(new frmMain()); } where 'AWSWndExceptionHandler' is my internal class for exception handling. Then I includ in the form a custom control 'GridCalendar' having a dragdrop functionality. Everything works fine a part from unhandled exceptions thrown in GridCalendar_DragDrop and GridCalendar_DragOver events...they get 'eaten' somewhere and I don't see them... For example the if I have following DragDrop event: private void GridCalendar_DragDrop(object sender, System.Windows.Forms.DragEventArgs e) { throw new ApplicationException("test drag-drop"); //testexc } when I drag and drop an item on the control, the expection 'testexc' is thrown but not bubbled up to the stack, so I don't get any error...the item is not dropped on the control, the form does not crash but the user doesn't know what's wrong... Any idea what I'm doing wrong? thanks Stefano Product Licensing RichLee5-Jan-04 0:03 RichLee 5-Jan-04 0:03  I've read Heath's excellent article on using encrypted XML for licensing a product, and will probably do this for one I'm about to release, as I really only want to deter unlicensed users, rather than make everybody's life difficult.

Explanation : my issue is that I want to drop a grid (datagrid,...) that is not linked directly to a dataset and that I paint cell by cell depending on the values of an array for example. This painting is for the main part a change of the background color of the considered cell and the drawing of a string in it. Need I a dataset nevertheless ? which I fill with my values and link to the grid ? How to draw a grid cell by cell ? Must I use the OnPaint event and cycle through cols and rows ?
