• Windows Forms Lost Article I cannot locate about WinForm Concurrency

  Ok.  I have been searching for an article that I read 4 months ago, and can't find it.  Maybe someone here has seen it. I have searched on keywords, and looked about 1000+ pages trying to find it with search tools. The article was about handling concurrency in a windows form application. The author explicitly says "since web environment is disconnected,&nb ...Show All

• Visual Basic tableadapter.insert

  I've been using this handy little function tableadapter.insert, but now I'm trying to figure out why I have to specify the parameters individually, rather than putting them into a nice array or collection. It seems like it should be able to be done. Here's the concept: I have a sequential file that contains data. I can parse this thing into multiple array elements, each containing the data for a field in an access table. Then, even if I had 50 fields, I could just call dim myDataArray(100) as string for i=0 to 99 'put some data in each array element next i tableadapter.insert(myDataArray) and it would work. But it does ...Show All

• SQL Server DTS Migration from SQL Server 2000

  I’m currently evaluating SQL Server 2005 to what advantages there would be to upgrading from SQL Server 2000. Our existing systems make much use of DTS so it critical for us to be able to run SQL Server 2000 DTS packages in SQL Server 2005.   Having installed the Enterprise SQL Server 2005 CTP successfully on a new Windows 2003 server and following the advice to install Legacy Components I find the Migration Wizard (under Legacy> Data Transformation Services) fails with the following error after entering source and target dialogs:   This wizard will close because it encountered the following error: Additional Inf ...Show All

• Windows Forms Need a fuction to avoid strange characters in e-mail

• Visual C++ CWinFormsDialog in MFC

  Is there any way of instantiating a CWinFormsDialog directly from an MFC MDI application's MainFrame object I have studied your MFC Windows Forms integration sample and noticed that the forms are instantiated either as doc-templates or created from a CFormView in an external DLL. I was hoping to open a winformdialog directly from the mainframe menu, but I am starting too see the limitations of the integration of winforms in MFC. Is there any other way of dealing with this issue Does the winform have to originate from a dynamically created document or could it be instatiated directly. I am trying to use it as a floating setti ...Show All

• Visual Studio Team System How to build project's default platform?

  Hi there How can I build the default platform of a project without enumerating all possible platforms in the <ConfigurationToBuild>-List An empty <PlatformToBuild></PlatformToBuild> aborts the build process. On the other hand a list with all possible plattforms will emerge MSB4126 warnings and what's worse, will break the build process in certain circumstances*. Thanks Volker * for details see my post: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=433646&SiteID=1 There is not currently a way to build the default platform / configuration for particular projects.

• Visual Studio Visual Source Safe Command Line

  Hi! What can be the advantages we can get by using the Visual Source Safe Command Line In any automated build environement with multiple code trees, the command line is much more simple and reliable when trying to create a specific version of the code set. Although the GUI is fine, the automation interface does not provide a simple method to get the "latest" version of a file that is PINNED to a prior version. Automated creation of command lines is also easy due to the simple syntax, and by logging them to a file, one can always see what was attempted, and repeat or test a single step by simply cutting the line from the fi ...Show All

• Windows Forms Hidden Fields

  Hi, I have a problem with hidden fields. Is there a possibility to hide fields from the Designer, which have the Property visible=false I have dialogs, which have a lot of hidden fields, so that the designing of these dialogs is very difficult. Thanks for your help Thorsten hmmm. . . do you ever show these hidden controls or are they just holders for data if you answer no to the former and yes to the latter, I suggest you are probably looking at things completely backwards. You shouldn't be using controls as a data structure to hold your data. The controls are the presentation layer - the ...Show All

• Software Development for Windows Vista Problem creating a custom activity with setstate

  Today I wanted to create a custom activity that does the following: First a question is asked using the MessageBox class.  The user can click Yes or No.  Based on the answer the workflow has to change to a different state. I added a property Question of type string to my activity.  Also I added a property Confirmed of type boolean to store the answer of the user.   Then I added a Code activity and programmed the question  part.  Then I added an IfElse Activity to my activity.  The condition is based on the Confirmed property.

• Visual Studio Express Editions Updating a combo box

  I am new to VB express and have what is probably a basic question that I just can't seem to find an answer to. I have a Vendor form which has several bound combo boxes on it. These controls display data from a parent Vendor table and a few related tables such as City. I can get the form to display, add, edit and save information for these vendors but I can not seem to figure out how to update the look up tables (or combo boxes). An example (the one I am struggling with) is the City combo box on the form. It nicely displays the values (that I have plugged in manually to a separate City table) in a dropdown and saves my selection back to the ...Show All
