• SQL Server Data Flow Task - OLEDB Source / Destination

  Hi Inside a data flow task, i have a oledb source and destination. In my situation, I need to pull data from a table in the source, but also hard code some columns myself, which means my source is a blend of data from table, hard coded data, which will then have to be mapped to columns in oledb destination. Does anyone which option to choose in the oledb source dropdown for the data access mode. Keep in mind, i do need to run a a select query, as well as get data from a table. Is it possible to use multiple oledb sources and connect to one destination, because that is really what intend to do here. I am not sure how it will work, or even if its possible. Basically my source access mode needs to be a blend of sql command and table column ...Show All

• Windows Forms How to get Checked Items/Nodes in Treeview Control

  Hi to all, I'm using VB.net 2005 and i'm kinda new at it. I had a Treeview with checkboxes shown on in. I already figured out how to populate Items on it, but my problem is that I can't find a way to get all the checked Items on it to its lowest node level. I hope somebody here can help me.

• Visual Studio Express Editions Using Modules....

  I have a VB project with a windows application form with a series of contols. I also have a module that contains a sub to run through the windows controls and then based on the checked boxes assigns boolean true or false... once that is done the sub runs a search on a database... The problem that I am having is that the sub is reading all controls as false for instance.. on windows form I have a checkbox named "checkbox1" Then I have a background Worker that calls the module and sub to run. on the module I have a sub that says something like this. Dim ThCheckbox1 as boolean If windowsform.Checkbox1.checked = True then ThCheckbox1 = True If ThCheckbox1 = true then <<< this is where the code does not ...Show All

• Software Development for Windows Vista ICredentialProvider

  Did anybody make a successful user logon using the new ICredentialProvider interface My credentials are displayed, but I can't make them to logon. And what worse - after 20 or 30 seconds, the winlogon crashes completely with no recovery possible excepting hardware reset. I thought I basically did something wrong and decided to wait for more detailed documentation or some sample code. But MS doesn't seem to put too much effort on improving their SDK documentation and I also found that at least one other programmer has the same problem: http://msdn.microsoft.com/newsgroups/default.aspx query=vista&dg=microsoft.public.platformsdk.security&cat=en-us-msdn-windev-winsdk&lang=en&cr=US&pt=&catli ...Show All

• SQL Server Pasword Data Type

  Hello ... I want to ask about the best data type protected for pasword colomn in SQL Server .. to make my DB more secure ... thanks ... That depends on the version you are using on the effort you want to put in your front end application. There are two ways. Server encrypted data (which is accessible in SQL Server 2005) or client encrypted data (or the combination of both). In SQL Server 2000 I always used a client library to encrypt / decrypt the data that was passed to the server. In SQL Server 2005 there is a server based functionalty for encrypting data.

• Visual Studio Team System Sharepoint vs. Version Control

  I was doing some contemplating this afternoon and I started to think about Documents in a project. Team System lets you store all kinds of documents in a Sharepoint portal which allows you to check them in and out. So it has a basic version control functionality. Besides having the document available to anyone on sharepoint is there any other good reasons to have documents in Sharepoint instead in the projects Version control Does it make a difference Does sharepoint use the same data base as Version control Which would be faster and/or more efficient Whether you use sharepoint or vesion control largely depends on your users. If the users are more comfortable with dealing with office docs (Word, Excel, etc.) from a web ...Show All

• Visual C# asynchronously or synchronously?

  I have seen the Ping code in this link: http://msdn2.microsoft.com/en-us/system.net.networkinformation.ping.aspx and i would like to know what is the difference between asynchronously ping and synchronously ping A synchronous ping, activated by Send(), blocks your program until a response is received. An asynchronous ping, activated by SendAsync(), keeps your program running; you'll need a PingCompleted event handler to know the outcome. ...Show All

• Windows Forms Form inside form. MDI?

  Hi, I am a C# newbie. I need to have an MDI behaviour for portion of the form. Like in Visual Studio. Portion of the app remains static(list of files, classes), and portion changes(the editor content changes depending on the file selected). So, the MDI behaviour is for the right panel(which contains the editor portion). How can I achieve this. R Put your static controls in panels that you dock in the MDI parent. The remaining area will automagically be used by the MDI child forms. ...Show All

• Visual Studio Trying To Use Solution Folders for Projects

  Good Morning All, I've been trying to use solution folders to structure our solutions into sensible chunks with much difficulty. Apologies for the dis-jointed nature of this post, but I'm trying to get down as much information as I can. As the solution template only allows physical folders to be created I've initially created all four of my projects in the solution's root. I have four arguments which hold Project types and are evaluated "OnBeginActions" for each of the projects. These look up the projects by name using the ProjectByPathExpressionProvider, passing in the name of the project to the PathExpression attribute. These arguements are evaluated at the beginning of the actions block, and are correct at that time. The ...Show All
