• Software Development for Windows Vista Persistence & tracking in beta 2.2

  I have created a simple application with 1 code activity, one delay and another code activity, in that order. If i'm enabling both the tracking and persistence, my workflow stops at unload If one if disabled, the other works just fine. Any ideas why this might happen Are you using a shared database Is the app hosted in ASP.NET or a win form app Can you post your code for creating the runtime and adding the tracking and persistence services ...Show All

• Windows Forms Inherited Toolstrips cannot be Designed

  When I have a base control with a public Toolstrip, and then inherit from the base control, the Toolstrip acts as if it is locked within the designer. Also none of the properties are accessible from the designer. If I manipulate the Toolstrip via code, it is public. This appears to be bug FDBK16876 which is supposed to have been fixed before beta 2 was released, but I am running beta 2 and the problem still occurs. Any suggestions to fix this problem would be appreciated, even if it is simply that the  bug will be fixed with the release of Visual Studio 2005. Peter Marshall. Find the bug, reopen it ...Show All

• Visual Basic Web Browser - VB.NET 2005

  Hi, I am trying to put together a web browser in vb.net 2005 - but having problems upgrading a vb6 app. I cannot bring up the print dialog to print the html, nor can I bring up other dialogs when I was previously using ExecWB. I used this for Internet Options, Find etc....all the functionality has simply fallen away in the upgrade. From what I read, these are obselete (inc the upgrade failure msgs in the IDE). Can someone point me to an example of a complete/near-complete Browser written in .vb.net 2005 or give me an of what I can try Thanks J Mark, brilliant stuff - its definately ...Show All

• Visual Studio Problem building Managed C++ project with Msbuild that has multiple assembly references

  I have a VS2005 solution that includes a Managed C++ project as well as several C# projects. The C++ project references several of the C# projects. All projects in the solution reference log4net.dll (as an AssemblyReference). My C++ project builds without any warnings using the VS2005 IDE. However, when I build the solution using MSBuild, I get zillions of warning messages such as: log4net.dll : warning C4945: 'LogicalThreadContextProperties' : cannot import symbol from '<some path>\log4net.dll': as 'log4net::Util::LogicalThreadContextProperties' has already been imported from another assembly 'log4net' For my managed C++ proj ...Show All

• Visual Studio Express Editions Simple way for database access?

  Hi there, I'm embarrassed to admit I've only just made the step up from VB6 and am a little lost! After much fiddling I've come up with the following solution for querying a simple database for names matching what is entered into a text box (and popping the results in a listbox), but I can't help feeling there must be an easier way than that pasted below. Any suggestions would be greatly appreciated! Private Sub tbSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tbSearch.TextChanged         Dim connection As String = My.Settings.psdatabaseConnectionString &nbs ...Show All

• Visual C# Custom Web Control Problems (should be easy?)

  I've created the following Master Page, Default.aspx using the master page and then a custom control that sits on my default.aspx page. Custom controls (header.ascx) has a simple <asp:image> and <asp:label> I'm trying to just have the <asp:Image tag" ImagUrl update from a method in the controls class backing file haers.ascx.cs file. For the ascx file I have this for my ImageUrl="<%=GetImageUrl() %>" and I've tried with a # also. In the backing file (cs) I have public string GetImageUrl() that simply returns a string to the path of my graphic I want to display in the image file. When I run ...Show All

• Visual Studio Tools for Office .NET vs VBA

  I have a number of Word templates that have many macros developed with VBA. VBA is buggy and upredictable. Will I be able to replace these macros with .NET in office 12. Jim, You are asking a great question, and the answer is (shock): it depends. I know this is not the detail you were looking for, so let me elaborate. VBA has some strengths, chiefly its proximity to documents. Within seconds you can start creating a solution for a document or template and once you are done, you send the doc. VBA is pound-for-pound one of the best toolkits around. However, it has weaknesses, and it is not designed for too much heavy lifting. As ...Show All

• Windows Forms Capturing form into bitmap

  This might be rather complicated to explain without pictures, but I'll give it a shot. I'm developing a data plot tool where the user loads a .txt file and can select which data to plot against time. The user can "hold" and plot data on top of each other and can turn a grid off and on. If you've ever used Matlab, it's similar to that plotter. The program runs entirely on one form (Form1). If you picture a form maximized to fill the screen, the left fourth is the data selection area, the bottom fourth is the hold and grid check boxes (and a few other things), and the remaining area is the plotting area. The method I used ...Show All

• SQL Server SSMS Command line startup not connecting to object explorer

  I connect to various SQL Servers. I have setup Windows shortcuts on my desktop to connect SSMS to these servers at a click. I have also selected to Open Object Explorer and new query at startup. This does not happen in above scenario. I have to manually connect the object explorer everytime by using ALT-F8. When I open SSMS without specifying a server and connect using the login box, it does connect the object explorer. What am I missing From what I remember command line connection options will only be used only for openning connected query windows upon startup, regardless of the SSMS startup options specified in Tools-> ...Show All

• .NET Development CertCreateSelfSignCertificate

  Hello. I have to generate certificates in my C++ application. So i have studied MSDN article witch describes CertCreateSelfSignCertificate. This article does not describe how to use this function. I'd like to get some example. Is it possible This really isn't runtime related so it's probably not the right forum for this question. However, here's the basic idea (at least how I've used it, signing with SHA1-RSA): First, create the key container by calling CryptAcquireContext. You specify a key container name, a CSP name (optional), a provider type (such as PROV_RSA_FULL), and some flags (I use CRYPT_NEWKEYSET to create a new ke ...Show All
