View 4 RepliesMy aim is to insert commands in to a console such as command prompt (except it isn't command prompt its actually a console engine for a game) and the commands will have shortcut buttons aswell which I can do my self, not a problem. My actual problem how ever is that I dont know how my vb form would recognise the process it needs to type in and how it would even find the text box to auto type the pre configured commands which I would have configured inside my form.
View 2 RepliesI want to make it so I have a form and a button and a web browser. The web browser will automatically load to a website that has boxes to fill in. In google chrome when i right click on the text box i can find the element or whatever its called. I am just wondering how I can make it so when I press the button it will change the text of the textbox on the website to whatever I want. Also how to make it press a button on a web browser as well.

View 2 RepliesI have a data-bound combobox that pulls values from a BindingList(of T). Combobox loads fine, correct values are displayed (I'm not using SelectedItem or SelectedValue). I'm using properties and connecting the data to the control via a bindingsource.
What I want is if the user types text into the combobox, I want the data from the bound table to change to that new text, i.e. edit the bound data directly.
Easy as pie to do with a textbox, but can't seem to get a combobox to work this way.
I was trying to use the validated event of the combobox to write the data to the datasource, but it doesn't fire when I press enter. Is that the way to do it? Can I not link the data to the combobox directly?
On the main form of my application, I have a Rich Text Box which is where the user will be entering information. The text is black. then, i have a button which calls the dialogue "Notes" A dialogue appears, with a rich text box. the user should then be able to enter text into the box, click "OK", and the text entered into the Notes dialogue be inserted to the rich text box on the main form -- with the font colour "Red". The rest of the text in the main rich text box on the main form should remain black.
View 2 RepliesI am having a problem with a entering sections of text into the same textbox without the other section of text disapearing. In other words, I have several buttons with strings attached to them. When the user presses one of the buttons the string does enter into the textbox. However, when the users presses another button the string from the first button disapears while the second string enters the textbox.
For example: The following code is what I have:
button nine_click
tbxResultSource.Text = CStr(9)
'button plus_click
tbxResultSource.Text = CStr("+")
How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.

I might be coming up with a few dumb questions over the next few weeks because I am trying to push myself to learn VB 2008. So I think this is the first.I have figured out how to get a datareader to pull data from a MySQL database, pass it from a module back to my form, but when I try to put it in a combobox, the text is always left-aligned. I had never thought about this before because I think I have only ever put text in one before in VB6. However, this time it is numeric and left aligned numerics don't line up well when the numbers look like
1000
2500

I would like to ask you a question about combo boxes . I want to insert a string into a combo box , but it seems I have a problem . First of all , let me specify that this combo box is set to only accept specific strings , which populate it when the form is loaded . Assuming that the combo box is located on Form1 , when it is loaded , this code is executed :
[Code]...
What is going wrong ? Is it that the combo box can not have that value because Form1 has not been loaded yet ? If that's the case what should I do ? I guess I could call the Load sub directly from Form2 in order to load Form1 , but I wouldn't like that because with the Load event some other code will run , which I don't want it to . So , is there any way to set my desired string into the combo box ?

I was wondering how i can loop through a combo boxes items display item field - and return the value for each - i want this to be generic regardless of the combo boxes data source - or if the combo box has been populated with a string list / class etc
View 3 RepliesThe instructions I'm following indicate that when user clicks the Add This Item menu item for a new order, the customer information should be disabled so that the state cannot be changed until the next customer.I've tried to validate that all the customer information fields are filled when user clicks Add This Item menu item. The trouble I was having was that even when you were alerted that you didn't fill one of the fields, you clicked on the message alert and then the customer fields were disabled before you could fill the empty one.
I've tried to make an if statement which checks if some are empty to alert else if they are filled then disable. This doesn't work either. I get Conversion from string "" to type 'Boolean' is not valid. I'm not advanced enough to understand this. I just know boolean means true or false or yes or no. I'm not sure the best way to handle this situation. I don't even know if locking the user out is wise since they might have wanted to correct something wrongly entered but my instructions are to validate that the fields are filled and then disable the customer information. I need to follow the instructions exactly.
This is what it looks like:
Private Sub AddThisItemToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddThisItemToolStripMenuItem.Click

I currently have my cute little first program made... I'm just stepping into the water with this programming thing. I made a program where you can select a shape from a drop-down list and then input some values and click a button and get the area of the shape. I have it working so that when a certain shape is chosen, certain fields are disabled, such as when you pick "circle" from the combo box, the "length", "width", and "number of sides" text boxes are disabled but the "radius" text box is enabled, thus allowing you to enter the radius and find the area. I want to make it so that when you first load the program, all of the text boxes for the length, width, number of sides and radius are disabled until you select a shape from the list. Currently I'm using

This works for disabling the correct boxes when something is selected, but I don't know if I'm even on the right path with that first part.

View 4 RepliesIn previous versions of VB, you could click on a label to gain the focus, and then type multiple of lines of text. In VB 2008, clicking on the control does not open up the control for editing. You can use the text property, but can only enter a continuous string of characters. How do you insert blank lines between paragraphs?
View 3 Repliesso this ones weird and i'm not having any success searching cause i'm retarted and not sure how to word it. I've attached a sample program very basic all you do is enter the text in the box and click display text and the message box opens up, no problems there, however what i want to happen is, i just want to enter the text and press enter and the message will display without actually having to click "display text".
View 1 RepliesI know how to enable the selected text style (bold, italic, underline...), maintaining other styles. For example, If I want to enable 'bold,' the following line of code works. [Code] I can also remove all text styles. I also know how to find out whether or not the selected segment of text has a style. But how do I remove the selected style without removing others? How do I disable only 'bold' while the selected segment of text has other styles like 'italic' and 'underline'?
View 9 Repliesim trying to disable a button until anything has been entered into two text boxes simultaneously.
So far i have tried:
If String.IsNullOrEmpty(TextBox1.Text & TextBox2.Text) Then
Button1.Enabled = False
Else
Button1.Enabled = True
End If
However it doesnt work simultaneously, the button will become enabled if i enter anything into either textbox, i cant have any of them left blank.
