View 2 RepliesVS 2010 - Populating ComboBox With Lines From Sequential File
Aug 20, 2011I'm working on a new version of something I had created years ago in VB6. What I was doing then is populating a combobox with lines from a sequential file ("title","URL") like this:
Open "data.dat" For Input As #1
Do While Not (EOF(1))
Input #1, NameInput, URLInput
cmbEntry.AddItem NameInput
Loop
And then checking against it on a button click to load the URL associated with the selected name:
Open "data.dat" For Input As #2
Do While (cmbEntry.Text <> NameInput) And (Not (EOF(2)))
Input #2, NameInput, URLInput
Loop
[Code] .....
What I'm trying to do in Visual Basic 2010 is the same process, though I'll be including a third field ("category","title","URL") to determine which one of four different comboboxes I add the entry to. I know I need to use streamreader, but I'm not finding much in the way of documentation or examples on how to do what I'm trying to do, which is:
- Populate one of four comboboxes with the second value in each line of an external text file, based on the first value in that line
- Set a string to the third value in a line of an external text file, based on the second value of that line
How to read these values from the file.
VS 2010 DatagridviewComboBoxColumn Dynamically Populating Items Collection?
Aug 10, 2011I am trying to create a basic quoting tool but got stuck on how to clear and change the item collection from within a combobox for a datagrid.What we have is a list of 4 columns like a. Device b.TypeofService c.State d.Price Inside a sql database. Data is also structure like above as well.
I have a datagridview where the user will populate a,b,c and the price will be display and a total at the end. However a,b, and c aren't related in my current application. The combobox will show all possible dinstinct values for each column.
This works fine but I want to refine the application to only show the values of b. which are in the database after the user select the value for a. I have tried searching on how to do this as I assume to the Contry/State/City situation but could not find anything for a datagridview control in VB.NET.
Can anyone point me in the right direction? If I cannot do this dynamically from within a datagridview I was thinking of maybe creating three combo box outside and having it populating the datagridview afterwards but it wouldn't be as nice.

VS 2010 Using WPF Ribbon In WinForms

I know about the ElementHost Control which works fine for created controls, but it doesn't seem to be able to host default controls, I could create a wpf control and put the ribbon in, but that seems like a terrible hack.(And lots of work since there are lots of controls related to the ribbon)

May 3, 2010this is my absolute first attempt at the mschart control in a winform, so any help would be appreciated - i have sales reps that issue quotes to customers and would like to plot number of quotes by month using the mschart control.I have a dataset populated with a single table with 2 columns in it - sales_rep and quote_issued_date (there's more, but i'd like to only focus on those two because they contain all the info i need)i have a windows form with an MSChart control dropped on to it. I'm trying to get this to work on a 'column' chart type.i'd like to count the number of records in the dataset per sales rep per monthi'd like to get the x axis to be months in the year (fixed, not drawn from the data) - jan thru dec.
i'd like to get the Y axis to reflect the highest count of rows per rep per month + say....10% (so the graph doesn't peak out at the top every time, it would be more for aethestics)i'd like to get the columns displayed in the graph to be each rep, each month (ie for january john has 10 quotes issued, bill has 5, tom has 31 - for feb john has 3, bill has 10, tom has 19 - etc etc etc) - because the form is just a quick visual, i'm dumping any code in the form load event and calling it good.
VS 2010 WinForms App Connect To Dll On Webserver
Nov 13, 2011I have a desktop WinForms app that I would like to be able to connect to my Sql Server database that I have through my GoDaddy webhost. Problem is not all ISP's forward the 1433 port (like mine) so I can't connect directly to the DB from any of my home computers without buying the expensive dedicated IP address package, which has me thinking since my website can connect directly to the DB I was wondering if it might be possible for me to make a dll that would have all of the database interaction through subs and functions and all my WinForms app would have to do is connect to that dll through http or something, anyone know if I could do something along those lines?

Winforms - 2010 Synchronize Two Access Databases?
Sep 15, 2011I'm writing a desktop application that uses the main access database that will be hosted on a central server, but there will be a laptop with the app on that has an offline mode so records can be created offsite. When the laptop returns I want it needs to be synced back to the main database.
Has anybody got any pointers on a way to do this, I've briefly read about JRO but is there an alternative / better method?
Originally, I was just going to write some custom code to do this, but thought I'd check to make sure there wasn't something already out there.
Winforms - Deploying A VB 2010 Win Forms Application
Nov 16, 2010I am deploying a VB.net 2010 winforms application, and when I install it on the client's machine, the install process also installs an instance of SQL Server 2005 Express. The application connects to a central SQL database on the server. To install, I am using the "Publish" option in VS 2010. Why does it do that? There should be no need for a local instance of SQL Express. Is there a way to avoid installing SQL 2005 Express (I know it is free, but I would rather not have it installed if possible).

Winforms - Load System.Drawing V4.0.0.0 On A Windows Form In Visual Studio 2010?
Mar 4, 2012I've decided to learn Visual Basic .Net as this is what some of my colleagues work with, and this will allow me to work with them on projects.I have purchased Microsoft Visual Basic 2010 Step by Step and downloaded the sample files. When I am trying to debug the first sample application (a Windows form), it is telling me that it can't load System.Drawing V4.0.0.0. However, if I create a new Windows Form application (C# or VB.Net) this works fine.
I had a look at the References tab in the project settings and System.Windows.Forms is referenced, but the version referenced is 2.0.0.0. I have removed and re-added this reference and it stays at 2.0.0.0 and I still get the error.Does anybody have any ideas as to what may be going on?
IDE :: Set Project Default For Winforms Projects S/ Default Modifier For Controls Added To Winforms Is Private
May 28, 2010Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
View 1 RepliesGet Templated Starter Database Driven Forms Generated In C# Winforms SQL Server Using Some RAD Tool Or Visual Studio 2010
Aug 11, 2011I hope I got all that in this question title. Let me explain. We are starting on small desktop app that will snowball into a big app with many forms. The database is SQL Server. It will have classic stored procs/functions performing classic CRUD functions. Given a table or stored proc in SQL Server what is the quickest way to create a form with all the hooks to maintain a table.
For e.g. lets assume I have table like this (most code below is pseudo code)
Table Employee
{
Name varchar(30)
DOB Datetime
Address varchar(100)
}
From this as source I want to create my Target which is form with 3 labels and 3 textboxes with add delete modify buttons (or OK button to add if not exists or modify if exists)
[Code]..
The code generation tool or technique that will be used should generate the correct db hooks (create SQL parameters, SqlCommand, execute sql.. basic try catch etc. Is there any open source tool to do this ? Some trick or templated approach via VS 2010 ? Worst case any third party tool ?
