We are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.
I need to create a new tree view, that is linked to a particular table.
Each row in the table has a parent id that links back to the table's primary key, and that defines the node hierarchy. So that relationship needs to be indicated in the databinding.
Am I able to use the standard treeview control in Visual Studio 2008, or do I need something extra to make this work?
I am trying to retrieve data row by row from my SQL Server and load them into my respective textboxes, I was doing the below code but of course it doesn't work as the For Each loop will load every single textboxes with each data retrieved,
i was create the .exe of vb.net project with sql server in backend. when i install it any other computer that time it is not connect to the data base. whta i do for that.

I have recently learnt vs '05 and am creating a project in vb.net '05.my question is-During project development, we connect it to MS SqL server 2005 express installed on my system and it works.( I use add datasource wizard,add sqldataadapter,add gridview control,generate dataset,connect dataset to gridview method). But after the project is finished and we create its executable, the project will be run on adiffrent machine with a different server name and hence a new connection string will be required.
How can i make my project detect server details and connect to it, at runtime ? because the user is only expexted to start the server and open my application.the app must connect to the new server on its own. If anybody has an answer or if you know some resource where i can find it, please post here. Any suggestions are welcome.
I have a windows app created in 2005 with sql server backend. There's also a web service that is located on a web server at a hosting facility. In my app, when ever it needs to interact with the data, it calls the web service.Ive been having this issue with several screens that Ive developed in .Net. The user enters a date, and saves to the database. When the datagridview is refreshed, the date that they entered always displays one day earlier. Eg. If they entered 4/18/2012, it displays as: 4/17/2012.
The date is correct in the database. I verified that the problem resides on the web server. The default timezone set on the server is GMT -06.00 Central Time(US and Canada) and it cannot be changed on the shared server. The time zone where I'm at is Pacific Standard time. I'm not sure the best way to deal with this issue. Here's one way I was thinking: Retrieve today's date from the server (don't know how to do this), and compare it to the date on my machine so I know the difference. Then, when I'm looping through the datatable, add this same number to the dates to display correctly. Maybe it's better to retreive it from the database via the sql?
I know i can run webforms and mvc views in seperate files, but i want to run the web server control output and events in/on the mvc view page, however, i keep getting this compiler error:
Line 38: <CuteWebUI:Uploader ID="UploadPic" runat="server" UploadType="IFrame" Line 39: FileTooLargeMsg="{0} cannot be uploaded! File size ({1}) is too large. The maximum file size allowed is set to: {2}." Line 40: TempDirectory="~/UserData/Images/TemporaryImages" UploadingMsg="Uploading..."
[code]....
i don't know what else do do, it just wont recognize the control name when im writing the event signature, right after the "handles" keyword, comes the server control name and then a dot, and then the event name, but as events its just giving me "Me", "MyBase" and "MyClass" options to run events for... doesn't let me access "FileUpload.OnFileUploaded" which is the control name & event name i want to write the sub routine method declaration (and subsequently method) and signature for.
I am trying to load CustomerName and PrintStreamACNO from tblCustomers to my dropdownlist. I am not getting the correct syntax on the binding and displaying.
Imports System Imports System.IO Imports System.Reflection Imports PSXSTL.Data Imports PSXSTL.Data.DataAccess
Tell me if I want to run a project that is created in vb.net 2010 and uses a backend SQL Server 2005.........how many changes can be done in a project to run on another computer....?what connection string I can write for it.......?which software do I need to install on the other computer to run a project on it.......
Just wondering how I can populate the child node in the following coding (I am able to populate the parent node but still wondering how to list out the child nodes)
===Extra Info=== I have a class to retrieve the Category Table (CategoryID, CateogryName, ParentID) and stored it via List<T>, when I need it, I declare CateogryDAL pass it to CateogryData.
I am trying to find a quick, step by step tutorial on on to implement a tree view for my intranet that will show all the computer accounts in my domain. (this is obliviously only step number one, because once i can see them, I want to be able to query information from them.but one thing at a time right?)
Is it possible and if so, how does one go about doing such a thing. I am loading a network directory in a treeview. Can the parent node be disabled, meaning it can't be selected, it's available for viewing only, but leave the child nodes selectable?
I am loading the directories from my C drive into a treeview using the code below. It takes forever due to the number of folders. Is it possible to have this only populate down 1 level and then use a NodeMouseClick Event to drill down further, in the same treeView, if the user desires to do so? How would I amend this code to do this?
The following code worked with 2.0 Framework, now with NPGSQL 2.0.11 and framework 4.0, this is erroring out despite Pooling=False for the connection. The underlying logic is that add nodes to treeview; for each node added, immediately get subnodes and populate...
