Filtering A Win Form With Sql Command?

Feb 21, 2011

I am using VB Net (2008) and SQL (2008) in Windows Forms, I am trying to filter a DataGridView , this DataGridView is being fill by Add New Data Source to my win form thus Dataset, Binding Source, Table Adapter are added to my form. Also my win form has 4 combo Boxes, a button and a DataGridView . Cbobox1 hold all the columns Name of the DGV , let say for instance that Supplier is the name of the column selected by cboBox1, CboBox2 which hold all the operators (being fill manually) like ( =, <> =< , >=, < , > , like, not like, between, not between, is null, is not null ), CboBox3 hold all the names of the Suppliers in alphabetic order, CboBox4 hold the same as CobBox3, Note: Cbobox3 and Cbobox4 values change as CboBox1 select a different column name. When using BindingSource.Filter every thing work fine, for this ex: let say cboBox2 is worth <> See part of my code EX:BindingSource.Filter = String.Format ("{0} {1} {2}", cboBox1.text, cboBox2.text, boBox3.text) except when using the operator "Between" I get this message āœBindingSource.Filter do not support this type of operator". So this is why I am trying to use the Sql Select Command. Wandering if it is possible to use the already Sql Connection and Table Adapter to build a SQLString Filter and also could I use the curly braces.

Send Command To Command Line From Windows Form Application?

Mar 11, 2010

I am trying to send a command to the external command line (cmd.exe) from the Windows form application that I'm writing in VB.NET (using VS2008).

I can only access the external program thru the command line (its not my program) and I must do so from a form app.

I am trying to use the following code. I am able to call a cmd.exe window, but I can't pass the command line my command.

Using mp As New Process
With mp.StartInfo
.FileName = "cmd.exe"

Send A Command To A Command Line And Then Submit The Command?

Apr 30, 2010

First let me say that I am not sure whether or not this should go in this section or the API section, and if it needs to be moved I apologize. My issue is fairly straight forward, but for some reason I cannot get it to work.

I am trying to send a command to a command line and then submit the command. I have been trying without success to get this to work in v2008 Express and v2010 Express, Here is the code I am trying to us:

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String _

Passing Command To Other Form

Jan 17, 2012

I have simple app with Form1, Form2 and Form3. Form 2 is being opened with button form Form1. Form3 is being opened with button from Form2. Form1 is startup form. I can call any public sub on Form1 from Form2,(using on Form2 command "form1.mypublicsubname". If I try to call public sub on Form2 from Form3 nothing happens. If I put simple Msgbox "Hello" in public sub on Form2 and I call it from Form3 I do get Msgbox saying Hello. If I put in same public sub something like me.mydatagrid.refresh nothing happens. Also if I try calling me.mydatatableadapter.fill nothing happens. I guess it has something to do with invoke but I just don't know where to start.

Have A Command Prompt Type Interface On Form?

Dec 27, 2010

I would like to have a command prompt type interface on my form. The only thing I am aware of is a textbox, but there are no facilities to have commands and output scroll without keeping the entire history in a variable. That would be an ever increasing variable, which is ridiculous. Is there an alternate way to use a textbox as a command prompt, or is there something else I can do. Another note, is the use of an array. I know I can increase an array with commands, but this is no good either, because some responses in the box need to be paragraphs in length, so even a separate array for command and output is too cumbersome.

Forms :: Command Line Like Interface In A Windows Form?

Jun 27, 2010

I am working on an application and I want the user to be able to enter commands into a textbox, and when they press enter, the command is printed in a rich text box, executed, and the output is printed. For instance: the user types move{file1}, {location} into the text box and this happens:

>command: move{file1}, {location}
>$ moving file1 to location
>job completed

How would I write lines to the rtb and execute commands when the enter key is pressed?

This works, partly.
Private Sub TextBox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles command.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
RichTextBox2.Text = Environment.NewLine + command.Text
End If
End Sub

it erases everything in the textbox before adding the line... I would also like to be able to make a database of commands, maybe a .dll or something, so that when the user types in something, it checks that database to see if the command exists, if it does it executes, if not, error.

Read Lines From Command Line To Windows Form?

Jun 9, 2010

Hey Overflow, I have an application which serves as a user interface for a spartan/command line program.

I have the program running on a separate process, and my application monitors it to see if it is responding and how mush CPU it is utilising.

Now I have a list of files in my program (listbox) which are to be sent to the application, which happens fine. But I want to be able to read text from the com-line so as to determine when the first file has been processed.

Com-line says one of "selecting settings", "unsupported format" and "cannot be fixed". What I want to be able to do is when it says one of these three things, remove item(0) in listbox1.

I thought of programming an event which handles com_exe.print or something or other, if possible.

I basically need something exactly the same as the GUI for RunAs but just for Internet Explorer (yes I know you can right click and go RunAs but that cant be done in this case). So the user would open this VB form, type their username and password in, hit OK and it would open Internet Explorer with their credentials (they log in under a generic account used by many people).
