I came across a post a while back which showed a custom rich textbox control which had line numbers in its margin. Similar to what you woudl see if you we coding in the VB designer and you had your line numbers viewable.
I think it was two controls in one (i.e. two textboxes: one for the numbers, and the other for the text). However I cannot remember where I saw it.

It works very well, except that the image that I use is right at the edges of the cell. I'd like to give it a small margin. How can I do this?
How do I use line numbers? For example, I'm reading a text file and I'll need to get the line number of the line "=====LINE=====" somewhere in the text file, and I'll need to get the text of the next line (+1 of the previous line, but I'm not sure how to do readline(line number)).
View 12 RepliesI have a 3 richtext boxs where I add each line together and output to a textbox, all is working great. But the problem I am seeing is that I paste the contents from a spreadsheet which strips off the leading 0 (zero) from a 9 digit number into the 1st RTB.What I require is that I need to read each line in the 1st RTB and if the digits are = 8 then prefix them with a 0 (zero).

I'm using a sunken label style and back color with a statusbar, no matter what settings I change, like hiding the grip and setting the grip margin to all 0, there's still a section on the right that won't go away. I want my status label to stretch all the way across the statusbar, is this possible?
View 2 RepliesWhen I put a label on a form, the Text property in the designer can be expanded to a multi-line edit box. (This is in VS2005.)
Is there a way to get that type of edit box on a custom String property of a usercontrol?
I'm using VB2008 Express. And I've been working on a "popup" to select a date range. The DateTimePicker isn't ideal because the purpose is to pick a date range, which will always be one full week, from Sunday through Saturday. The control works just fine and I'm pretty proud of it. My problem has to do with the border added when using ToolstripControlHost for this. I've included a screenshot and my code.
In the code below, assume there exists a button named "btnTimePeriod", below which I desire to show a panel, which contains a few custom items, and the panel's name is "pnlDateRangePicker".IT WORKS... but it doesn't look right. The panel itself is 147 x 326 pixels, but notice in the attached graphic that it's adding a border around the panel which I don't want. There's a border on the top, bottom, and left... but for some reason the border on the right one is especially large. Although my code doesn't expressly set it, AutoSize = true so I would have expected it to shrink around the panel.
As required, my code already does set ShowCheckMargin and ShowImageMargin false. I haven't included the code for the DrawDateCalander Sub because it's not relevant. I believe even a blank panel would yield the same result. I have no idea where this margin is coming from.
Private Sub btnTimePeriod_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTimePeriod.Click
Call DrawDateCalendar(DatePart(DateInterval.Month, FirstDisplayedSunday), DatePart(DateInterval.Year, FirstDisplayedSunday))
Call ShowControlBelow(btnTimePeriod, pnlDateRangePicker)
End Sub

But this makes every cell in column editable. Is there a way i can make some cells editable in column? If you know how to do it,
I'm looping through an array of controls and need to know which controls an end-user has the ability to (via JavaScript or directly) change the value that gets posted back. Where can I find such a list?
So far I have this:

Return TypeOf control Is IEditableTextControl _
OrElse TypeOf control Is ICheckBoxControl _
OrElse GetType(ListControl).IsAssignableFrom(control.GetType()) _
OrElse GetType(HiddenField).IsAssignableFrom(control.GetType())
End Function

View 1 RepliesI need a control that will allow me to do a few things.
The control should be similar to Listview in detail mode, in that it lets me show numerous rows, each row with multiple columns. However, I want it editable in place... that is, the user can (if I let him) click on a column and change what is stored there.
The next thing I need to do is set a graphic in one column, text in another, a playback controller in a third, and a trackbar control in the fourth. Every row will look like that.
The final thing I need to do is be able to control how a row is painted... either the entire line or by putting a graphic image (like a button) in a column when it is not being edited.
Barring all of that, I can put all the controls I need into a single user control, then I need some listview-like control that will allow me to add that control to it.. and have it be operational.
I am writing a windows forms application in Visual Studio 10 on Windows 7.
I have a spreadsheet in excel with three headers:
Project Name The name of a project i'm working on.
Requested Role The job title/profession of the project employee. (example: mechanic, manager, engineer)
The name of the employee.When i click on the Person's name i want another page or tab (specific to this person) to appear showing details about them such as their name, job title, how long they worked, what project they are doing... etc. (similar to a Facebook profile)
When i click on the project name i want another page or tab (specific to this project) to appear showing details about it such as the requirements, the deadline, who is currently working on it... etc.
Furthermore, i would like to set up two levels of access:For the specific pages i was thinking of using the tab control but i want it so that i can search through the list of projects or names, select one, and then it brings up the page about it.The levels of access is the least of my worries.
How can I basically lock a default property so the user cannot edit it? For example, if I wanted to lock the BackColor property, how can I make it so the end user of the control can't edit it?

View 1 RepliesI am wondering if anyone has any idea how to make the controls stack and fill up the available space left by a control if the control is hidden or removed from the UltraGridBagLayoutPanel.
Example:
[Textbox 1]
[Textbox 2]
[Textbox 3]
[Textbox 4]
[Textbox 5]
If I hide [Textbox 3] as of now, it will disperse the space left equally and pad the remaining text boxes with the space. However, I would like it to do this...
[Textbox 1]
[Textbox 2]
[Textbox 4]
[Textbox 5]
Where all the text boxes will move up and [Textbox 4] will completely consume the space left by [Textbox 3].
Well I've finally decided to upgrade some of my vb6 applications. Anyway I have two forms that are very similar one is customers one is vehicles. One of them is working on form load and one of them isn't. The one that isn't working I've traced the point it stops down to where there is a green line left of the code on the left bar of the development environment. This green line doesn't exist on the form that works. What the green line in this photo means? [URL].
Bigger Picture [URL]. I found a page that says the green simply means the code was saved but it's only on the form that stops working right after the execution of the sql statement. For some reason while stepping through the code it returns to the show command that was called to originally open the form right before the form opens but it skips everything with the green line next to it. I went and disabled tracking and it went away.

I am still learning vb.net and decided to make a "horse race" to get a better understanding of inheritance and such. So first of all I made a horse class that inherits from the picturebox. I gave the horse properties such as image, height, width, x-position, and y-position. I also gave the horse a speed(between 1-1000). My idea was to have the horses start at the starting line and get them to move using a timer. Each time the timer fires the move method executes. The move method creates a new random number(seeded by DateTime.now.milisecond) between 1-1000, if the random number is lower than the speed of the horse it will "move" adding 1 to the x-position property.
Here is the code for the class :
Public Class Horse
Inherits PictureBox
Private m_speed As Integer
Private m_picture As Image
Private m_xposition As Integer
[Code] ....
Now things work as I expected for the most part, I created two new horses and gave them values, if one is "faster" than the other it will move faster. Here is the code I use to create two horses and put them in an array:
Private thisHorse As New Horse(700, My.Resources.Horse__Small_, 20, 30, 100, 100)
Private secondHorse As New Horse(700, My.Resources.Horse__Small_, 20, 150, 100, 100)
Private horseArray() As Horse = {thisHorse, secondHorse}
I give the horses visual representation using a loop during the load form event:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
For Each i As Horse In horseArray
i.Visible = True
[Code] .....
The only problem is if I give them both the same speed they seem to move in unison. I have tried adjusting the x-axis increment and have seen them both jump at the same time. Now I realize since they have the same "speed" they should have close to the same movements but wouldn't the random factor in the move method create some discrepancy between the two? I have ran this multiple times and am still unsure what the problem is.
