Restricted Textbox Code (Specifically, Building A Class Library With Code)?
Jan 2, 2012I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.

Aug 31, 2011I have a search engine that will use a webservice to search through my database to find 3 specific things. I don't even know if it will work like this, but I have a dropdown list on my main page to select Product, Feature, Description. From what the user selects, the webservice should then go to an if statement to use the correct SELECT statement and find results for the search.
Will someone help me figure out how to fix what I've written to make it work? Please don't be too critical, I don't have a lot of experience. I have also been researching SQL Injection because I have a lot of code that is vulnerable so keep that in mind when you look at my code.
I can't get the blue squiggly lines to go away that are underneath the DropdownList1.Value instances on the WebService page.
WebService:
<WebMethod()> _
Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String()
Dim Feature As String = DropDownList1.Value
Dim Description As String = DropDownList1.Value
Dim Product As String = DropDownList1.Value

View 4 RepliesBuilding Database App With Vb?
Sep 3, 2009I am trying to write simple database application and try to understand ADO.net as well.say I have 2 table
1. table emp with the following field (empId, empName, empPhone, salary, deptId)
2. table dept with the following field (deptId, deptName, deptLocation, deptManager)
emp table is link to dept table via deptId.so I try to build a form with 2 data grids the top will be dept data grid and below it is emp data grid.I try to do this with out using the wizard so I know the flow and understand how to link together step by step.
in the form load section:
dim conn as new system.data.sqlclient.sqlconnection(connectionString)
dim daEmp as system.data.sqlclient.sqldataadapter
dim daDept as system.data.sqlclient.sqldataadapter
[code]....
I am kind of stuck on what to do next, I think the next step is to creat dataview from my understanding before mapping it to the datagrid, but on data grid documentation it say it can only filter datarow, it can't filter data column on the dataview.
I would like to be able to display deptName, deptLocation, no the whole column on the table to data grid, and when user select a record from dept datagrid then the employee info (empname, empphone, empsalary) is display on the second grid (again not the whole emp column table).
the user can update, add or delete emp record from employee data grid by clicing on update button, on update button callback routine I need to put something like.
daEmp.update()
from what my understanding then I need to create update, insert and delete routine and attach it to daEmp so the data grid know how to sync with sql server, so when the user say add new record since the data grid doesn't have all the field display, i.e deptId column is not on data grid, how the table know what the dept id would be? I'd like to learn without the wizard 1st since once I know how everything is link then it is easier to debug since the wizard create lots of file and it's everywhere which make it very hard to understand what is happening for someone new to vb & ado.

Im not worrying about ui's at the moment just and exe (hello world style )

Building An Installer Of A VB App Using SqlServerCE
Jan 2, 2012I have a VB app that uses a sqlServerCE database. Everything works quite fine on my computer.
When I try to install it on other computers I run into problems. The message "Unable to load the native components of SQL Server Compact corresponding to the ADO.net provider of version 8080"
I am testing on a Win XP virtual machine.
My first attempt was to use InstallShield LE to create the installer. I defined ServerCE as a prerequisite and when I check in add/remove programs it exists, but I still get the error.
Then I tried building the installer with the Microsoft installer. This adds the dll to the program directory automatically, but I still get the error.
I read the KB article referenced (874247) and recompiled the app as an x86 application only, and rebuilding the installer, but have the same problem.

C# - Building A Roguelike In Silverlight (or WPF)?
Dec 10, 2009I've been toying with the idea of building a web-based Roguelike game using Silverlight (or maybe just a desktop game using WPF).
If you don't know what a Roguelike is, it's a type of graphical RPG where the graphics are rendered using text. Because the graphics engine is relatively simple, you get to spend your time building features into the game and it's possible for one person to quickly build something fun.
For instance, a typical screen might look something like this (the @ is the player, # is a wall, the other characters are things like monsters, stairs, and items):
I'm an experienced ASP.Net dev and I'm just getting started with Silverlight. Is there a particular approach I should take for this? To provide some background, in Winforms, most standard approaches are too slow -- the text ends up updating with a visible, ugly blink. I'm thinking something to do with the Canvas might be appropriate, but even better would be to somehow draw a screen into a buffer and then instantly flip that onto the screen so that it becomes visible instantly.
But I don't really want to mess around with DirectX right now - I'm hoping WPF can get me to where I need to be without a big learning curve.
Update: So this turned out to be pretty challenging. I tried a lot of different approaches and I was finally able to get it to actually render fast enough, but I think that to make it blazing hot fast you should probably build a sprite map of the font you want to use and work from that instead of trying to use any of the built in font rendering stuff. I didn't do that.
When I got the core rendering engine done, I ended up with some annoying artifacts related to quirks of font rendering (even fixed width fonts are sometimes a liiitle bit wide...), and when I finally worked that out I discovered libtcod, which is a very impressive roguelike engine that has a C# wrapper. That's all console based. I played with it a little and I was blown away.
As of 1.5.1, everything I've touched in libtcod works great except for the mouse input stuff and one of the keyboard input modes (which I think they recently ditched), but everything you need to make a roguelike is in there, and that includes several line-of-sight, pathfinding, and even dungeon generation algorithms. It's pretty advanced visually. Have you ever seen an RL like this?
In a nutshell, it's possible to build a roguelike with silverlight, but I wouldn't go in expecting it to be easy unless you've already got a strong silverlight or game dev background. You're going to be re-inventing some serious wheels, and even with a powerful toolkit that allows to focus on gameplay, there's no shortage of things to do.
C# - Telerik RadComboBox Not Building?
May 20, 2011I'm receiving a very peculiar Telerik error, I was wondering if any of you with Telerik experience had come across this one before.
I'm using a RadComboBox, when trying to build I get this error :

[code]....
It all runs as expected when I force run the project, but it won't build successfully or allow me to publish. The error message just doesn't make any logical sense.I've tried using System.EventArgs assuming that the Telerik event args derive from it. But still no success.
