SQL Server Problems running SQL Agent Jobs & SSIS Packages
I'm having some difficulties with the SQL Agent and running my SSIS packages. At present, I have several packages that import data from Oracle, a few that use a JODBC connection and several more that transfer data from other SQL servers (2000) I originally had the SQL Agent log in as a System Account, and although the pacages run fine if I manually right click and execute them, if I add them to a Job they fail with a login error. I then changed the login details to my domain account and the Jobs that run accross the SQL servers run fine. However the others that use Oracle and JODBC still fail with login errors. I've tried creating Credenti ...Show All
Visual C# Visual C# Look and Feel nice in XP, ordinary in 2000, why?
Hi, I downloaded and am running Visual C# Express on my Windows 2000 machine. At first, I was slightly taken aback by the clumsy, clunky look of some of the dialogs in the IDE itself. That is, some of the buttons were strangely large and the size of some dialogs just didn't come anywhere near the professional, smart look of say, Office 2000. For example the "Edit Rows and Columns..." dialog if you right-click on a TableLayout panel. I'm not being picky here, I'll send a screenshot when I get home - it looks quite unproportioned and particularly ugly ;-) I have 1152x864 resolution. I was guessing that it was something to do with the ...Show All
Visual C++ Problem calling JavaScript from C++
Actually, all examples where you use a UI button for a JavaScript call work; but when a call is done without any button being pressed, there's an error! The program does a JavaScript call when window loading is complete: DWORD WINAPI CallJScriptLater( LPVOID lpParam ) { CHtmlCtrl* a = (CHtmlCtrl*) lpParam; CStringArray strArray; strArray.Add("Picture@500"); strArray.Add("Video Clip@200"); strArray.Add("Some more@50"); // first element in array // Name @ size @ free_space strArray.Ad ...Show All

Windows Forms app from website - not trusted?
Hello If I publish an app to my website, when I try to install it, I get an error saying "application has been blocked...high security risk". Is there any way around this Thanks Hopefully I can clear up the signing issue for anyone currently trying to mess around with Click Once. - Click Once apps require Authenticode digital certificates to be signed. - This is because under Windows SP2 all programs downloaded over the Internet are checked for a certificate so that the Publisher (that means you or your company) can be verified.

Visual Basic How to open a dialog dynamically
I want open a user written dialog of which I determine the name only at runtime. This means I have Dialog name in a string variable. Normally I open the various dialogs using a Select Case statement, but it seems that this coding can be a lot more simple if I can solve something on the New part in the following snippet dim DialogToOpen as string dim dlg as new form DialogToOpen = "Dialog1" dlg = Dialog1 <---- this is where I need some advice if I could write: dlg = DialogToOpen that would be the answer, but you cannot assign a string to a dialog object! Or maybe you can if dlg.showdialog = dialogresult. ...Show All

Visual Studio Team System What is an area?
I was just testing team explorer and all the menus, and I see an option where you can add Areas and Iterations, could somebody give me a brief explanation of areas in sofwware development in cmmi Thanks Areas are a way to divide a software product into features & subfeatures. For example, the area path for one of my bugs might be something like: VSTS -> Team Foundation Server -> Version Control -> Client UI -> Branch Dialog (smaller projects probably wouldn't need to go 5 levels deep) Iterations, as you probably guessed, are more for tracking development over time. They're commonly referred to as "milestones ...Show All

.NET Development looking for a good XML schema wrapper tool/code generator
We extensively use XML schema in our application, exchanging XML instances between the client and the server. We create typed dataset wrappers on top of the schema to speed up the development. These wrappers are just used internally and are not exchanged between the system components. Some features enabled using the typed dataset as a wrapper are missingin from the classes generated by XSD.exe so we dont' use it. On the other hand dataset aren't so good at managing schemas with imported namespace, any and so on. Is there any third party tool that is able to create rich and complete wrappers around XSD schemas We are ...Show All

Visual C# How to display some ListViewItems with ghosted icon? Or how to reduce the opacity of an icon?
I have a ListView in which I display some file names with their respective icons. For few of the Items I want to display their icon as ghosted. The ghosted effect is the way icons are displayed when you cut some item in the Windows Explorer or the way Windows Explorer displays hidden files. I do not have static icon files, instead I am using the Win32 API SHGetFileInfo and ExtractIconEx to get the icons for the file names. The only place I could find this being done was in IShellFolder::GetAttributesOf(). But as this application is not a shell extension I don't see how I can use this.
