• Software Development for Windows Vista Resuming Host-Runtime and Checking for Needed Services

  We are building a workflow "host" which will load and run various workflows for the organization. Most workflows will require the Persistence and Tracking services, while some will need the ExternalDataExchange Service and other custom services we design. What happens if we've loaded several services and have workflows running, persisted, etc. and the host is taken offline/crashes. When the host restarts and resumes any persisted/queued workflows will the host automatically invoke the required services for each workflow I know that we can check (from within the runtime host) to see if a specific service is running, and if it is not we can add it to the runtime. But what happens when the host comes back after a crash. Is the ...Show All

• Visual Studio Express Editions expression cannot be evaluated

  Hello all of you., I get in my program for several variables: pie_y_best CXX0030: Error: expression cannot be evaluated Why is this, The program seems has no problem in getting a value of the variable, but it looks the debugger is not able to get it. Thanks for your feedback. All the best, Victor Oke, here is part of the code (the program is bigger of course): for (scanline = 0 ; scanline < rows ; scanline++) { After this statement I have a breakpoint. If I hover with the mouse over 'scanline', no information given (I see the correct value for 'rows'). In the Locals window of Visual C++2005 (8.0.50727.42), I get this error: scanline CXX003 ...Show All

• Visual Basic Needing Some Knowledge About Visual Basic

  What are the limatations of Visual Basic - I am familiar with html, and dhtml, I'm learning CSS & C+ currently. -- Anyway, my hobby is making all kinds of websites. My cousin wanted me to make her a virtual pet site. Like Neopets R something interactive, where you can have items, stores, pets, and stuff like that. I don't know how to make this, and I've been trying to learn for what seems like forever. However I don't know what to search for to learn this. I found Visual Basic yesterday, and it is soo much easier than notepad. I haven't found out everything about it yet, and I was hoping someone can point me in the right direction, what to search for to learn how to make a virtual pet site.. I know it sounds childish but it's imp ...Show All

• Windows Forms Problem validating a bound text control

  I have a text box that is bound to a class property. I want to do the validation in the Validating handler of the text box. However if I set the e.cancel = true in the case of invalid data, the validated handler is not called which is correct, but the data is passed over to the bound control. This should not happen. The msdn help at http://msdn2.microsoft.com/en-us/library/ms229603(VS.80).aspx States the following.  "When you use data binding, the data in your control is synchronized with the data source during execution of the Validating event. If you cancel the Validating event, the data will not be synchronized with the data source." ------------------------- So it should work as I expected. Here is the test c ...Show All

• Visual Studio Tools for Office Overriding load of add-in

  Hi All, I dicovered few days back that the user can simply do a run and use /a switch to override the add-in that would be deployed onto his/her m/c (the add-in that I've created after so much of hardship ) Was wondering if there is an override for this override (I want all my users to use my add-in ). Regards, Pavan PS: I guess this is true for all add-ins either developed using VSTO or using IDTExtensibility2 interface Hi Pavvu No, there's no way to "out trick" the Safe Mode start-up switch. That's there for the same reason Windows can be started in Safe Mode: for trouble-shooting configuration problems. As someone who has supported Word for over ten years, I can tell you Off ...Show All

• Visual Studio Express Editions I have two listbox and I want that when the user touch the scroll in one Listbox the other listbox will move to the same row

  Best Regards, Yaniv Pinhas Good work NoBugz. Several folks have been asking for this on different forums. For those who want to use this without adding a control to the toolbar; Just add NoBugz's 'MyListBox' class to a windows project and dynamically create a couple of these listboxes in the startup class form. (Or you could probably modify the designer.vb very carefully .) Use the code below to dynamically add the listboxes and implement the rest of NoBugz's solution.

• SQL Server Reporting Services Keeping format when deploying to the Report Manager

  Hi, I am trying to place text boxes in the header of a matrix in order to give each row group(i.e. each drill-down area in my matrix a header). This can be done in Reporting Services 2005. However when I deploy this report to the corresponding url(Report Manager) it seems to be losing its formatting and not displaying correctly. The textboxes placed in the matrix header seem to go all over the place. I do get a warning when I deploy the report -> [rsOverlappingReportItems]. Some renderers do not support overlapping report items. How can this be rectified Hi DKLdev, I am having the same issue. I need to add column headers in the matrix. Can you explain a bit more. Many thank ...Show All

• Software Development for Windows Vista Error calling events on a suspended workflow

  Hi, I'm running a state machine workflow, and trying to fire events on an existing instance, but getting the following error: {"EnqueueItemOnIdle cannot be called on suspended workflows."} System.Exception {System.InvalidOperationException} I tried calling the Resume() method on the WorkflowInstance immediately before raising the event, but that didn't make any difference.
