Re: Problems with ListView and columns (finally fixed) Luis Alonso Ramos12-Aug-02 19:36 Luis Alonso Ramos 12-Aug-02 19:36  I fixed this problem!!! The problem was I was calling lstView.Clear() and that removes all items AND columns. I now call lstView.Items.Clear() and everything works as it should!

But if any control in the form has the TabStop-property set to true, there will no event be raised before leaving the control. The only event raised is the KeyUp event of the form, if the KeyPreview is set to true. But when it is raised, the focus is already in the next control. Does someone know a way to check, if the tab-key is pressed? I thought I could work with the Leave-event, but I don't know, if the control will be left because of the tab-key. Thank you for your help, Michael muenchen-michi@gmx.de Re: notify if tab-key is pressed Luis Alonso Ramos24-Jul-02 6:32 Luis Alonso Ramos 24-Jul-02 6:32  I'm not sure, but there is an AcceptTab property (and AcceptReturn too, I don't know if it only applies to multiline)... you could try setting that to true and handling KeyDown/KeyUp/KeyPress... then you call SelectNextControl to move the foucs to the next control in the tab order. -- LuisR ──────────────   Luis Alonso Ramos   Chihuahua, Mexico   www.luisalonsoramos.com "Do not worry about your difficulties in mathematics, I assure you that mine are greater." -- Albert Einstein Re: notify if tab-key is pressed Anonymous24-Jul-02 11:11 Anonymous 24-Jul-02 11:11  Hi Luis, thanks for you answer. But these properties only apply to multiline textboxes. So this won't help me. Michael muenchen-michi@gmx.de Re: notify if tab-key is pressed Luis Alonso Ramos24-Jul-02 11:41 Luis Alonso Ramos 24-Jul-02 11:41  Why would you like to trap the tab key? to be able to prevent the user from tabbing away from your control?? what for? maybe we can find another solution. -- LuisR ──────────────   Luis Alonso Ramos   Chihuahua, Mexico   www.luisalonsoramos.com "Do not worry about your difficulties in mathematics, I assure you that mine are greater." -- Albert Einstein Highlighting in RichTextBox? leppie24-Jul-02 3:58 leppie 24-Jul-02 3:58  Hi all Has anyone a clue how to do or approach this?

Re: Highlighting in RichTextBox? jparsons24-Jul-02 4:36 jparsons 24-Jul-02 4:36  I think that the only way you're going to be able to do this is if you add the code with the rich text format codes applied. You will have to get the text from the box via Rtf. This will give you the text of the box with all of the format codes applied. You can then manually edit it and put in the format codes that you want. However this is a very large pain in the ass. Jared jparsons@jparsons.org www.prism.gatech.edu/~gte477n Re: Highlighting in RichTextBox? leppie24-Jul-02 5:17 leppie 24-Jul-02 5:17  Thx But SelectedRtf (and Rtf) from a RichTextBox seems to be very picky. I was try just to copy SelectedRtf from one RichTextBox to another and 9/10 times exceptions was thrown. I will try it though. Maybe it was escaping or something.

ComboBox - MultiColumn mikasa24-Jul-02 2:53 mikasa 24-Jul-02 2:53  Hello, I am trying to find out if anyone has a ComboBox Control for Visual Basic .NET that will handle Multi-Columns. Also, I have seen a Drop-Down TreeView Control as well on this site...has anyone Implemented this into .NET yet? I could really use both of these ASAP! Re: ComboBox - MultiColumn David Stone24-Jul-02 12:37 David Stone 24-Jul-02 12:37  The TreeView control can be downloaded at www.asp.net. It is part of the IEWebControls package. As for the other, I haven't seen one yet...

I want to use Cookie to keep Shop Cart information at client side. I also defined a class and some functions to work with them, for example adding an item to Cookie (Shop Cart), updating items and deleting an item. But when I use these functions, no changes apply to the cookie value. I think it is because the class doesn't have access to change Response and Request of Page. Please let me know how I can solve this problem. Here is the code I developed (Unnecessary parts are not shown.) C# Class: public class ShopCart { /* ... */ /******************** Cookie Remove_Name ******************/ // Removes an Item from Cookie public void Remove_Name(HttpRequest thisReq, String Cookie_Name, String sName) { HttpCookieCollection MyCookieColl; HttpCookie MyCookie; MyCookieColl = thisReq.Cookies; MyCookie = MyCookieColl[Cookie_Name]; if (MyCookie!=null) { if (MyCookie.Values.Get(sName)!=null) { MyCookie.Values.Remove(sName); Response.Cookies.Add(MyCookie); } } } } // class ASP.NET Call script: ShopCart myShopCart = new ShopCarts.ShopCart(); myShopCart.Remove_Name(Request, "eShopCart", "item_01" Look forward to hearing from you all.

Now i'm looping through them and updating them one at a time .This is taking much time .Is there an efficient way of doing this?

Then add the entire table to your Database.

IOW If you have to alter a property during the foreach loop, you will get an exception and you have to revert to the for statement. As far as I can see , the foreach statement is purely a shortcut for IEnumerator en = Array.GetEnumerator(); do { Object obj = en.Current; } while (en.MoveNext()); MYrc : A .NET IRC client with C# Plugin Capabilities.

Re: multiple updates SimonS24-Jul-02 21:33 SimonS 24-Jul-02 21:33  The idea of creating a new dataset with this data and then adding it as a whole to the database might work (as per post). Another idea would be to package all the data into parameters (i.e. have a parameter each for: ID, Desc, Status and add all ID's to the ID parameter and all Desc's to the Desc parameter etc...) You can then split these up using T-SQL. I have some script for this if you'd like. You're probably going to have to weigh up the performance as well as whether or not the "tasks" table can be recreated each time.

When creating a task, we can supply the user and password in which the task shall run. The problem I am having is that I want to schedule a task to run with all the priviledges of the current authenticated user, in other words, the person running the program should be the person executing the task when the time comes. I am trying to avoid saving the password of the user and sending it to the task scheduler. Are there anyway I can tell the system to grab my credentials and use that to run the scheduled tasks? Thanks, netmodules jparsons23-Jul-02 10:37 jparsons 23-Jul-02 10:37  I've recently been playing with command line compiles of my C# projects. Beeing accustom to C and C++ I'm used to building all of my files into object code and then compiling all of hte object code together in the end. Looking around I thought that "csc /t:module" was the answer. However i was very mistaken. Everything will compile with /t:module just fine and it willa ll apparently compile together at the end by using the /addmodule switch. However the resulting executable is still dependent upon the .netmodule files. Is there any way to combine the .netmodule files into one assmebly so that it is no longer dependent upon all of these small little object files. My main intent here is to create incremental builds so that I'm not recompiling all of my classes at the same time. Any advice would be appreciated.

I will warn you, however, that netmodules aren't supported in the IDE and aren't widely used. csc already supports incremental compilation with the /incremental switch, which should meet your needs. If that's not fast enough - or you don't want to use it - I suggest you break your projects into multiple assemblies.
