• Visual Basic Passing arrays from vb .NET to ActiveX control (*.ocx)

  I have an application written in Visual Basic 6 that uses an ActiveX control written in Visual C++ 6. I'm moving the visual basic 6 application to visual basic .NET (2003). The problem is when I try to pass an array from the visual basic code as a parameter of a function of the control. In Visual Basic 6 the code is something like this: Dim dummy(10) as Long '... 'some code '... myActiveXControl.myFunction(dummy(0)) myFunction expects a reference of the first element of an array of Integers. Passing the first element of the array works fine in visual basic 6. But if I try the above code in vb .NET, changing the definition of the array for this one (type Long in vb 6 is Integer in vb .NET) : Dim dummy(10) as Integer ...Show All

• Smart Device Development XMLSerializer: sibling elements order - normal in .Net Framework but random in .netCF!

  Hi, all I have used the same classes, and the same serialization code to run a test program writing out an XML document from a data object. It turned out that for an element which has multiple child elements, the order of the child elements remained the same in Framework 2.0 as defined in the class, but it was random in CF2.0! It isn't alphabetic nor anything I can tell but a random order... This is annoying because then the document generated in CF2.0 wouldn't pass the same schema, based on which the classes' code was actually generated.  Is the problem a bug -bonnie Bonnie, Despite .NET's tendency to preserve the order of XmlElement's, unless you explicitly set the XmlElementAttribute.Order pr ...Show All

  Hi all, I'm trying to use the observer pattern on updatng GUI controls. I have some controls (TextBoxes, Buttons)... I don't know how to link the Update method to the control.

• .NET Development Does 'promary key' make a table faster?

  Hello, I'm wondering if I always should have a primary key in each table, even if I don't use it Thanks The primary key ensures that there's at least one field which ALWAYS contains a unique value for each record. This is essential if you're doing relational queries against the table. I can't think of any compelling reason not to use one. ...Show All

• Windows Forms Copy files using custom actions in Setup Project

  I have a project to deploy but there is a file (non code), that will need to be copied to a directory on the install machine, that is not the application directory (app dir). To make maters worse, this directory will be different on every machine. So I can not use the File system editor. My thinking was to use a custom action on the Install_AfterInstall event. This action would look in the application directory where that app had just been installed and copy this file to a specific dir on the users machine. The problem is this dir could be anywhere on the users machine. The good news is the dir will always be named the same. How do I get the app dir name so I can copy this file at the end of the setup process Will the file exist on t ...Show All

• .NET Development questions about Automatically Generating Commands (DbCommandBuilder )

  from http://msdn2.microsoft.com/en-us/library/tf579hcz.aspx When the SelectCommand property is dynamically specified at run time, such as through a query tool that takes a textual command from the user, you may not be able to specify the appropriate InsertCommand , UpdateCommand , or DeleteCommand at design time. If your DataTable maps to or is generated from a single database table , you can take advantage of the DbCommandBuilder object to automatically generate the DeleteCommand , InsertCommand , and UpdateCommand of the DbDataAdapter . I'm confused that if my selectcommand involves more than one table, these commands can not be generated automatically, is this true so during actual development, probabably our sel ...Show All

• Windows Forms ClickOnce file share icon?

  This is probably a really basic (maybe stupid) question, but I have done several searches and haven't found an answer Here's one version of the documentation I'm referring to: Install from the Web or a Network Share Using this strategy, your application is deployed to a Web server or a network file share. When an end user wants to install the application, he or she clicks an icon on a Web page or double-clicks an icon on the file share. The application is then downloaded, installed, and started on the end user's computer. Items are added to the Start menu and the Add/Remove Programs group in the Control Panel . Where is the icon they are referring to in the statement: double-clicks an icon on the file share When I pub ...Show All

• Visual C++ Problem with Visual C++ after upgrading VS2005 with SP1

  My team develops software with Visual C++ on Visual Studio 2005. When we upgraded from Visual Studio 6, we discovered that for the executable to run a computer that does not have VS8 installed on, the new C redistributables had to be installed. We went through the installation, and indeed the executable created with VS8 worked. We had some of the developers' compilers upgraded from VS8 to VS8 SP1, and suddenly the problem occured again - executable created with VS8 sans SP1 works on the destination machine, while executable created from same sources with VS8 SP1 will not. Anyone ran into this problem Any know solution Thanks, Tzal. We had a similar scenario in past for one of our project dev. ...Show All

• Visual Studio Team System TFS SP1 Installation Failure

  The build component seems to install without error, but the first component fails every time. I can fix our installation afterward by reinstalling the KB that's required before installing SP1, and fixing whatever changes the install made to the Domain accounts uses for the application pools and services. But it would be nice if we could actually get SP1 to install without error. I'm thoroughly disappointed with the low quality of this install fall so far. I've seen alpha software work better. Anyhow, I've got this log file with a ton of information and lots of errors. Rather than posting it here (because it's simply huge), is there someone I can send it to who can help We'd really like to get this installed if possible. I hear thi ...Show All
