Smart Device Development Setup and Installer Package
I have developed CF2.0 application and did CAB Project and MSI installer package to deploy. I do see lot of downloads on my application but all the downloaders are disapppearing after download. I accidentaly found the reason that, when they try to install my Compact Framework 2.0 application with the supplied Installer the installer asks for .Net Framework 2.0 to be present in the Desktop since my application and Setup projects were developed in Visual Studio 2005. I do not think many users will have this framework installed in their desktop. As soon as it is prompted to download Framework for Desktop it discourages to con ...Show All

Visual Studio LAN Booster
Unable to use SourceSafe LAN service, performance of SourceSafe operations will not be optimal. I have been working on this for the past 3 days. This was a SourceSafe database created in 6.0 and was working correctly with 6.0 integration. This is what I have confirmed: The Visual SourceSafe LAN Service is running. I installed the COM Internet Services Proxy on the Server (saw in a different post) and rebooted the server. Added Tunnellng TCP/IP as well and rebooted. UseHelperService = Yes is in the srcsafe.ini. Looked in DebugView and do get the errors mentioned. Tried SSServiceTest and that fails too. I tried to fi ...Show All

Visual Studio "This page cannot be displayed" in Visual Studio Documentation
Hi, From several years now, we have been buying the full version of the MSDN documentation. It's been helping us much since then. Unfortunately, we have been experiencing some problems using it on our Intranet ( Our network is not connected on the Internet for obvious security reasons ). There seems to be more external links when refering to an other article in MSDN than before. The question is, do you plan on using more and more external links inside new MSDN articles or are they isolated errors that slipped through testing Cause if it is indeed the new philosophy, buying the MSDN help becomes more and more useless, since the onlin ...Show All

Visual C# ColAutoResize
In my app I have 2 different DataGrid's and they each reside in seperate forms. Each only has a single DataTable as its DataSource. Upon a change in either Grid's DataSource, the method below is called to resize the columns. In Grid1, I display the table, but sometimes hiding certain columns using Table.Columns[index].ColumnMapping = MappingType.Hidden. In Grid2, I display the table, and sometimes want to hide columns. However, on this table I also use the most commonly explained way to highlight specific cells of the table. I create DataGridTableStyle, which has a DataGridColumnStyle for each column. Also overwriting the DataGridTextB ...Show All

Visual Basic What good is this?
Dim PrgrssBr as New ProgressBar ... and what can you do with it Thanks. Hello zdrae, The purpose of the dim <variable> as New <type> syntax is to allow you to declare a variable and initialize it all in one go. It is really just "syntatic sugar" for the following equivalent vb code: dim myList as ArrayList myList = new ArrayList Choosing between the two forms of syntax is really just a matter of style. Some developers like to write their variable declarations / initializations in a compact way, so we support that. Hope this helps. -Scott Wisniewski Sof ...Show All
