• Software Development for Windows Vista Building a "long process" WF runtime

  So I'm going to be implementing a set of workflows triggered by application events. Now, sometimes there will be a long wait between one activity and the next. Is WF designed to just "wait around" constantly running or should the different workflow instances be persisted in SQL Server until they need to continue Sorry for such an intro question but I can't buy a book on beta software! :-) I spent some time this morning with persisting workflow instances to SQL Server. That works very nicely. Considering WF is a runtime that needs a host, has there been a lot of discussion on building a robust host application for workflow instances I see my workflow instances being initialized, delayed, and restarted numerous times before ...Show All

• Microsoft ISV Community Center Forums View users who are logged in to access database

  Hi - I have an access database and i have multiple users who log in and based on their login information they can then complete certain functions within the database. Their login is stored in a global variable (loginname), which remains with them throughout their session until they log out.

• Windows Forms Draw on top of Image

  Hello. I have a custom control that loads a large image and displays it on screen (using scrollbars). The problem is that I want to draw on the visible part of the image (the part that is currently on screen) and I want to be able to modify the things that I'm drawing (i.e. if I draw a line on top of the image, I want to be able to remove that line later). I did something like this, with the help of this forum: (where Image image = Image.FromFile("picture.jpg"); ) protected override void OnPaint( PaintEventArgs e) {    e.Graphics.SmoothingMode = SmoothingMode .AntiAlias;    Rectangle src = new Rectangle (-AutoScrollPosition.X, -AutoScrollPosition.Y, this .Width, this .Height);    Rect ...Show All

• Visual Studio 2008 (Pre-release) HorizontalAlignment on DataTemplate in GridView (bug?)

  We have a ListView with a GridView, witch has a DataTemplate on the columns. The DataTemplate consist of a border with a TextBox. In May CTP the HorizontalAlignment=Stretch on the Border and TextBox worked fine, but this doesn’t seem to be the case in June CTP Best regards,   Thomas Andersen   Aha, I got the right solution from Microsoft: <snipped from Connect> This change is a result of a bug fix where ListViewItem was not respecting the default value of its HorizontalContentAlignment property. The default property value is Left so your TextBoxes should have appeared left aligned in the columns but because of that bug, ListView was stretching them. To get stretching beha ...Show All

• Windows Forms split view application

  I've been looking around for how to do a split view application. Much like Outlook the application I'm trying to create has buttons you click on the left hand pane and then another view in the right hand page which changes depending which button you click. I have added a splitContainer with the thought that maybe I could add and remove user controls from the right panel. I can't see any immediately obvious way of doing that though. I would be interested to know how any else has gone about implementing this. Thanks for any help or pointers.

• SQL Server SR 2005 - Code works in preview, but not when deployed.

  SSRS Version: 2005 I've created a report that has a simple function that cycles through a multi-value parameter list array and returns a string value of each list item that was selected seperated by a comma. I use this so I can display in a textbox which items were selected. The code works when you preview the report in the designer; however, once it's deployed onto the server, the textbox that calls the code displays: #Error. I've been researching this problem in other forums, but the only thing I've come across talks about security permission when running a custom assembly. I'm not using any custom assemblies. Can anyone help me out with this problem and let me know how to resolve this issue Below is a copy of the code I'm using. ...Show All

• Visual Basic Debugging

  Deploying PDB file with application helps to find name of souce code file and line where is error. But, when I handle errors in Try... Catch statement, how to read that information All I have is ex object but I can't find there what is souce code file name and line of error. Is it possible to read that information (from PDB file or whatever) while error handling There's not much you can programmaticaly do with the stack trace, not that I think you'd really want to.

• Visual Basic Workbooks.Open(fileName): Cannot fix Overload Resolution Error

  Okay, I have searched and searched, read and read, and every solution I have found is simply not working.

• SQL Server osql batch command does not return any records when executed using Scheduled Tasks

  I've read a similar post but there was no solution It seems a bit weird.  I created a batch file which runs osql which runs a very simple SELECT statement - no parameters, simple WHERE clause, etc.  When I execute the batch file, it generates a file which contains the results of the query.  But when I run the same batch file using Scheduled Tasks, it does not return any record at all.  The account that I use to execute the batch file and execute the query is a member of the sysadmin role.  Am I missing something out ...Show All

• Smart Device Development CImage::GetBits() leads to segfault with CImage::LoadFromResource()

  The following code doesn't work: CImage *image = new CImage(); if (!image) return -1; HINSTANCE inst = GetModuleHandle(NULL); image->LoadFromResource(inst, IDB_BITMAP1); if (image->GetBPP() != 24) return -1; LPBYTE UNALIGNED bits = (LPBYTE) image->GetBits(); if (!bits) return -1; *bits = 0; Last operation causes a segmentation fault. The bitmap was succesfully loaded and image->Draw() works fine. Value of bits was 128.

• Windows Forms Finding a the related row position in a datatable form a dataview

  Hi All, Sorry about the complexity of the following. I have a DataSet containing a number of tables, one table SLAWarnings is shown in a DataGrid through the DataView dvWarnings. Attached to the table is a BindingManagerBase bmWarnings which is used to fire the PoistionChanged event. On this event I set up a temp relationship within the dataset to another table. I then use the .Position of the bmWarnings to GetChildRows of the related table and loop through them adding the rows and other stuff to a tree view. The problem I have is if the DataGrid has been sorted, the .Position then applies to the DataGrid row and NOT the DataTable row needed for the relationship. Can anyone give me some help/advice on how to get the underlyi ...Show All
