• .NET Development Multiuser in ado.Net

  I have this windows forms application used by one user. Now there are 2 users on this application. Everything is running on a a small network with SBS 2003, SQL 2000 and Windows XP clients. The forms application is coded in VS 2005. As i am using ADO.Net anywhere in my application, all data is always cached in the client side . This means that the 2 users don't see (immediatly) the changes made by the other user (which is unacceptable). How should i solve this Do i really need to replace all ado.net code with custom business objects I don't know the terms to search for a system like this. Hope someone in here knows more than me. I have to say I never implemented something like this on a big system. Instead of using ADO the cl ...Show All

• Software Development for Windows Vista Imapi2 on Vista RC1

  My builds are now broken on the SDK (which is now at version 6 ! !) that matches Vista RC1. http://www.microsoft.com/downloads/details.aspx FamilyId=117ECFD3-98AD-4D67-87D2-E95A8407FA86&displaylang=en Anyone know what is going on I don't see the sample code or anything that corresponds to ImapiV2 anymore. This is very confusing :-| I guess I won't be getting much work done this week... Hello foobarX, The tag above makes me think you somehow got the WDK (Windows Driver Kit, which is somewhat like the new DDK). This will not contain the IMAPIv2 documentation and samples, as all of that material is in the SDK. The link you posted seemed to be to the SDK however, so I'm not s ...Show All

• .NET Development Exception: DataTable internal index is corrupted: '5'. on ...

  Hi, I have a problem with bindingsource component in framework 2.0. I have a combobox bound to a bindingsource which is also bound to a dataset with 2 related tables and a datagridview bound to the same bindingsource. What I want to do is : When the selectedindex property of my combobox changes, the corresponding cell value must be changed in the datagridview. But although the value in bindingsource changes, datagridview does not display the new value. That value is displayed after I move the mouse over that cell and make it invalidate its region manually. Another error I caught is the one that you can see as the subject of my post. I do not know why i have that message when I try to change the property of ((DataRowView)mybindi ...Show All

• Software Development for Windows Vista TC23 - Problems undoing registry changes after installation rollback

  Hello, I'm trying to pass test case 23, and even if I finally got the installer to remove all the files that it installed (I had problems with reportengine.msm of Crystal Reports) after the rollback, I realized that it didn't undo the registry changes made during intallation. I think I read (in a post in this forum that right now I can't find) that we should make a little script to launch after rollback, where we could undo those changes manually. Well, this is what my imaging tool says about the registry changes after rollback: - Values added: 91.900 - Keys added: 97.700 - Values deleted and changed: 1000 Those are lots of changes !! I realized that our controls' registration information is still in the registry, even th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Video/Animation Playback

  Hi, I'm currently writing a library (for XNA/DirectX) for animation/soundless video playback, and I have a few design questions for the pros out there if you don't mind answering them : I'm having my animation class inherit from game component, and update the frame depending on game time in the overriden Update method, and render it in the overidden Draw method, but even when I preload my textures to render, playback is choppy. Not sure exactly why, but I notice this only when I have significant number of frames (I noticed it with 100 frames, but *not* with 10/15). This problem may be linked and solved by the 2nd point, so please read on. When I preload all the textures for the frames in the animation (and the no. of frames ...Show All

• SQL Server Opening a URL in reporting services 2005 opens whatever IE window

  How do I get reporting services 2005 to open a new IE window when touching a URL. Otherwise it grabs whatever one is open (not any order) which writes over what I was viewing. This is extremely frustrating. Our company uses LOTUS notes sametime as a netmeeting software which uses IE and it keeps choosing that window and "knocking" me out of the meeting. What can I do One thing that might work is unchecking the "Reuse windows for launching shortcuts" option under "Browsing" section located on the "Advanced" tab of IE's Internet Options. The down-side to this fix is that it only affects your user profile. This fix would have to be performed for each user's profile. I' ...Show All

• Visual Basic Focus Question

  I have made a custom control where when the user enters the control, the BackColor Changes then when it Leaves go back to white. I does fine when it is "Enter"ed by the user but when i focus the control at runtime, it seems to blink "MistyRose" then back to white apparently, it Enters the control, then executes the Leave event but focus is still on it. Why did this happen Also i want to create the effect that when the user clicks/enters some control when he should start with another, to focus the first control, i can seem to get that, i used: something like: if Condition = False Then Control1.focus() End If Show us the code you are using - its probably related to the events which yo ...Show All

• Smart Device Development Little Help

  I am using vs2005 and when I click to deploy my software to my handheld for testing I get the message "loading symbols for c:\Program Files\Microsoft.NET\SDK\CompactFramework\v2.0\Debugger\BCL\mscorlib.dll" This message shows at the bottom and it never gets past this point. It never actually deploys and runs my software. Has anyone ever seen this error. That is all right, but I need to see what version of .NET Compact framework you have installed on the device. Please go to the device's \windows folder and start cgacutil application - it will tell you what version/s of NET CF you have. Having only .NET 2.0 as you mentioned is is not enough - you should have .NET Compact Framework installed ...Show All

• .NET Development ReadXml with read count

  Hi, I need to load a DataTable from a XML file but not all the data, instead, I want to load a custom number of rows from this XML file. ReadXml function reads all the schema and data from the xml file but if the data is too large or if I want to read only 10 records to show as a preview to the user, what I should I do I think XmlReader is the solution to this problem but I do not know how to use this weapon. Thanks for any efforts and time spent. Thank you for your reply which helped me to be sure on the way to follow to start implementing the code. There is no solution or question on the internet other than mine and I think that makes things difficult as you say too. I will surely ask you the questions I met a ...Show All
