• Visual Basic SQL vs. MS Access

  Dear readers, I am new to VB2005 coming fromVB6 using only MS Access databases. It seems that the obvious database type of choice is SQL. Are their any problems using Access databases for an application that runs on a network, storing multiple monetary transactions, and huge customer databases. Also...... If I distribute my application using SQL databases, do I need to ship it with an SQL server package such as SQL2005 or SQL Express, or can my application be a standalone package creating and accessing SQL databases. Thanks MH Traditionally MS Access has not been very good with multi-user updates, and you'll find that they very often go corrupt.  If you really are talking about huge ...Show All

• Visual C++ Interface inheritance from another interface

  Hi, Im working on an application build on plugin using interfaces. Now im trying to expand my normal plugin interface iPluginAPI with a few more methods / properties to allow it to access more restricted functions in the main program. I did this by creating a new interface iPluginExp which inherets the base methods from iPluginAPI and has some methodes / properties from its own. So every 'normal' plugin implements iPluginAPI  and the 'privileged' plugins implement the iPluginExp interface. So far so good. When I'm  going to use these plugins and load a normal plugin using the code below, everything goes well. When I load a privileged plugin and I try to cast the created instance to iPluginExp , it throws a expetion with ...Show All

• Windows Forms Auto generating buttons

  Hey All For a little project of mine, I need to creat buttons from either an ArrayList containing the names of what the buttons should be called or from or from a database table. Depending what was is easiest to understand/do. They all have to be in the same windows form, so that if the ArrayList contains 10 names then there should be generated 10 buttons on load, and if one of the names is removed from the ArrayList then the button should also be removed. Hope anyone will be able to help me. Thanks Anders Lykke System.Collections. IList buttonNames = new System.Collections. ArrayList ( new String [] { "one" , "two" }); private void Form1_Load ( object sender, EventArgs ...Show All

• Windows Forms serialize TreeNode-derived classes

  Hi, I want to serialize my custom class derived from TreeNode. After searching on Internet I found many answers that confused me so I'm going to as many questions hoping to get the right answers from you. 1) TreeNode is inheriting from MarshalByRefObject so it's not possible to serialize it. but I can do it like this so what are they talking about Code : TreeNode treenode = new TreeNode(); treenode.Nodes.Add("1"); treenode.Nodes.Add("2"); treenode.Nodes.Add("3"); treenode.Nodes.Add("4"); System.IO.FileStream file = new System.IO.FileStream(@"c:\test.dat", System.IO.FileMode.Create); BinaryFormatter serializer =new BinaryFormatter(); serializer.Serialize(file, treenode); ...Show All

• Microsoft ISV Community Center Forums VB MACRO IN SHARED WORKBOOK(EXCEL)

  HI, PLEASE UPDATE ME HOW TO RUN VB MACROS IN SHARED EXCEL WORK BOOK THANKS, Aravinda Hi, You cannot share a workbook, well you can but only one user will have write access to the data. If it's just code/forms your looking to share so that more than one user can run the code against their own set of data then your looking to create an addin (xla file). To share the addin you need to place it on a network share. There is an option in Excel, I believe it prompts you, when installing an addin to specify whether the addin should be copied to the local machine or kept in the share, if you keep the addin on the share then all users share the code and any changes to the addin are reflected for all users using it.

• Visual Studio Team System What privs to I need to use witImport and witexport?

  I can use TFSDeleteProject fine, because it prompts for a username and password.  But witimport and witexport don't prompt for a username.  What am I doing wrong   My username is authorized as Admin.   >witexport /t 166.20.96.241 /p ERsim /n Meeting TF30063: You are not authorized to access 166.20.96.241. That post does seem to be the same problem as what I am experiencing.  But I do not understand the answer that Dan Kershaw posted.  I can do a TSFDeleteProject which does prompt for username/password, but this doesn't at all have any effect on getting subsequent witexports to work.  Nor does starting up VS and its prompting for username validation.  ...Show All

• Windows Forms Framework and Windows Installer not present

  I am deploying a project on a large number of user machines. On a W2K machine, when I tested the MSI, it of course, did not have the Framework or the correct version of Windows Installer. But I did get the expected error messages. So I am going to issue install instructions that state the order of install is to first install these two items, and then install the application. Do any of you do anything different Ok, all is well now. I had gotten in the habit of running the MSI directly (double-click), because the setup.exe would error out so often. Running the MSI gave me the condition I spoke of earlier in this thread. When I went back to running the Setup.exe, I again would ...Show All

• Software Development for Windows Vista Working with the built in Administrator account

  The app I am working on definitly needs all those API calls that require "elevation" under Vista. It seemed that installing the application to launch under the built-in admin account was the answer. It seemed that Vista compliant installers will be able to install an application to start for every user but have it launched as another user, ie: the built in admin account. This seemed like it could solve a lot of our problems, but now in Vista RC1, the built in admin account is disabled by default, and this can be a big problem. Does this simply mean that the user can not directly log in under the built in admin account *or* does it mean that you can't even launch an application under the built in account If the answer ...Show All
