• Windows Forms Bug in application settings? (Properties.Settings.Default)

  In design time, I created a new setting, called "stringBag".. its type is StringDictionary. Then my code does this: StringDictionary sd = new StringDictionary(); sd.Add("ab", "Blue sky"); sd.Add("abb", "Here is text"); Properties.Settings.Default.stringBag = sd; Properties.Settings.Default.Save(); For some reason, it doesn't save it. It saves other settings if I specify them.. like simple strings or integers. But the StringDictionary doesn't save. Any ideas why I know it doesn't work because I look at the .xml file and see it has not written the StringDictionary to the file, but other settings I changed were saved just fine. ...Show All

• Audio and Video Development Superimposition filter with MF

  Hi, I've been working for a little time with Media Foundation, trying to implement an application I had once created with DShow. This is a C# form using a wrapper and a filter to play a video file applying a transform. With DShow, I was able to write a filter to write on the video, using a HBITMAP and the m_pinput properties in the CTransformFilter Class. In MF, I'm not able to reproduce the same process like that. So my question is : "Is it possible to write a filter with MF, which would allow to write on the video (using Superimposition) Thanks The Grayscale MFT sample is there mostly to show you around the mechanics of implementing an MFT; of course we expect MFTs in the wild to be doing somethin ...Show All

• SQL Server Loosing database connection when device power-off (native oledb code)

  Hi, I experienced this problems on both Windows Mobile 2003 SE and Windows Mobile 5.0. Its native development (c++, oledb, atl and mfc). It's quite simple to reproduce... 1. open a database 2. open a rowset on table A (whatever, valid of course and with both IOpenRowset and ICommandText), read datas and close rowset 3. power off 4. power on 5. try step 2 with another table (failed on openrowset with error 0x80004005) or try table A (sometimes working because of cached memory, sometims failed on Read Datas). 6. being stuck ;-) Our work-around was, in case we loose our connection (identified by error 0x80004005 on openrowset), we close it and re-open database... ugly for sure, but working.

• Software Development for Windows Vista UI.Automation and IE7

  I am trying to understand to what extent I can automate a web app using UI.Automation and IE7. I was expecting to be able to interact with the page however all I see in UISpy are the items like the Status Bar and the favorites etc. Am I missing something obvious Any pointers appreciated. Thanks, -jim Current IE support is based on MSAA, and UI Automation clients are seeing the objects through the fallback MSAA provider. As a result, you don’t see what you’d see from a browser with native UI Automation support. ...Show All

• Visual Basic hopefully a little problem with listbox/getfiles

  dear ladys and gentlemen, i've got a maybe little problem with the path in an listbox, when i use this code: For Each foundfile As String In My .Computer.FileSystem.GetFiles( _ ( "c:\nuproject\txtfiles\komm" ), _ FileIO.SearchOption.SearchTopLevelOnly, "*.txt" ) ListBox1.Items.Add(foundfile) TextBox1.Text = "" Timer1.Enabled = True Next then i got a list of all txt-files in this directory. so far so good, but i don't want the path be in there. so c:\nuproject\txtfiles\komm\ should be hidden! thanks for your solution!

• Visual Studio Team System S "An unexpected error has occurred" After Upgrading Portal Server to SP2

  I did a dumb thing and upgraded the Portal Server to SP2. WSS had apparently upgraded itself to SP2, and I couldn't add custom web parts (from Microsoft downloads). So I thought I'd upgrade to SP2 on the Portal Server. Now, I can't get to the default page or my home page, they all give: "An unexpected error has occurred. Web Parts Maintenance Page: If you have permission, you can use this page to temporarily disable Web Parts or remove personal settings. For more information, contact your site administrator." So now I am sweating bullets, because it appears I can't unistall this SP2, and I don't really want to do the restore route if possible. I have the link for the hotfix for this problem, though I don't want ...Show All

• SQL Server Distributed Transactions between servers on different VLANs

  Hi there, I have two SQL servers, SERVERA and SERVERB. They are on two different VLAN's within our corporate network. They are physically only about 5 feet apart. SERVERA is SQL2005 while SERVERB is SQL2000. I am running a distruted transaction as a result of an insert on SERVERA which then causes a Stored procedure stored on SERVERA to insert a record on a table on SERVERB. I know my syntax is correct, 'cause I can get the Process to work between two servers (one SQL2000 and the other SQL2005) on the same VLAN. But when I run it in the problem environment, I get the following error message: SQL Execution Error Executed SQL Statement: INSERT INTO Tablea(recordid, recordtext) values(3, 'Testagain') Error source: .Net SQLClient D ...Show All

• Software Development for Windows Vista VB6 SendKeys doesn't work

  Why does the VB6 function SendKeys not work under Windows Vista Beta2 Build 5384 Does anybody know, if this will be fixed in final version VB6 is out of date, obsolete and unsupported. Any app that uses WPF ( which some apps on Vista may well do ) is not going to support SendKeys, or anything like it. As VB6 is unsupported, I doubt anyone is going to 'fix' it. In fact, it's probably a 'fix' that you can no longer write apps that manipulate other programs, which can obviously be used for bad as well as good. ...Show All
