I am trying to display a small icon in a combobox so I want to use EM_SETMARGINS to set a margin in it. I am using this
Private Sub SetLeftMargin(ByVal lhWnd As IntPtr, ByVal lMargin As Int32)
Dim lLongValue As Int32
Dim Result As Int32
Result = SendMessageLong(lhWnd, EM_SETMARGINS, EC_LEFTMARGIN, lMargin)
End Sub
It works OK with a ritchtextbox but not with the combobox text field.

I can print and almost everything works. Basically I used KB 811401 to create a RichTextBoxPrintCtrl.dll and add it to my tool box. I have a Page Setup and a Page Print. I call Setup and change the margins. Then I call print. But I always get default margins. The margin settings I put in the Page Setup don't "take".
Here is my relavant application code.

So, I'm adding a label programatically and I'm in need of altering the top margin a little bit to the value 8. I can't do that the obvious way, so what's wrong with my thinking?
Dim LabelAdapter As New Label
LabelAdapter.text = "Adapter"
LabelAdapter.Margin.Top = 8
This gives me the error "Expression is a value and therefore cannot be the target of an assignment".

View 3 RepliesI'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 RepliesI've built an app, that draws text to four rectangles on a pre-printed page with a design, I'm wondering what the margin refers to?
Also our printer doesn't print all the way to the edge, there's a white border, about the height of this little guy:If I printed from a printer that prints to the edge, will the text be in the same position as it would be if it was printed with the border around it, the text should be in the exact same position right?
1. How to get 0 padding/inner margin in the cells? I want just the border as a colored line at the next close pixel to the control in the cell. Or if border set to none, I want the controls with no gap.
2. How do I actually add/remove rows& columns? I thought this was by setting the .ColumnCount property, but if I set it to 3, and then try to access the third column, it gives exception, so it's obviously just two columns, although it also looks like 3 on the form. ? I created it in designer with 2 columns though. But I don't understand how this hangs together..

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

Today I went to the user's site for a demo. The program works fine on my HP LaserJet 1018. Data is entered into a RichTextBoxPrintCtrl and then printed on one of four labels as selected by the user at print time. For the top left (landscape) label, I set margins (50, 570, 60, 460) on the DefaultPageSettings and it correctly prints a label starting 0.5" from the left and 0.6" from the top.
On the HP OfficeJet Pro K550, the label size, left to right and top to bottom, is correct but the top mrgin is about 0.75" and the left margin is 1.0". So the label looks correct but shifted right and down so of course it does not print ont he label. I used MS Word 2003 and printed a document with 0.5" margins all the way around and it worked.I found an options in the printer's advanced properties to "minimize margins" and another to "emulate laser printer margins" but neither had any effect on my output.
It seems when I change some code while working with practice files I get green veritcal lines in the left margin of the code page I am writing. What does it mean?

View 2 RepliesI 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.
I am having issues when trying to populate a combobox that is dependent on another combobox. Populating the first combobox works as expected but attempting to set the value member or display member properties of the first combo box cause its selected index changed event to fire. That event seems to fire before the first combobox is fully loaded. The issue is then raised when trying to populate the second combo box, since it is dependent on having a valid value member to complete the dynamic sql statement, and at that point in time, there is no value member.
I can�t imagine that this is difficult but searching hasn�t yielded me any results. Should I be using a different event? What is the right way to do this?
I have a simple workaround in place - not allowing the second combo box to attempt to populate unless the first combobox has an index greater than zero but this hack is no good since it clearly prevents the user from selecting the first element in the first combo box.

I have created my first ComboBox form but now I am stumped. I am using VB Express 2010. What Toolbox or Property buttons do I use to generate code for the following:

(3) Items.ADD (to add the options on the drop down)
(4) Dropdownstyle

I have a button on a form and 3 comboboxes, each populated with a list. The outcome I'm attempting to programme is, descriptively; Button Click
[Code]...
I'm trying to display some data in my combobox, the strange thing is that the combobox displays all data that has 4 four columns (I only want to display 3 columns out the four) but its not displaying rows that only have three columns?
For example
Text File
Column1, Column2, Column3, Column4
I only want to display columns 1, 3 and 4 so I use the following coding
For Each Line As String In System.IO.File.ReadAllLines(Path)
If String.IsNullOrEmpty(Line) Then Continue For
Dim Columns() As String = Line.Split(New Char() {" "c}, StringSplitOptions.RemoveEmptyEntries)
If Columns.Count < 4 Then Continue For
Combobox1.Items.Add(Columns(0) & " " & Columns(2) & " " & Columns(3))
Next Line
But some of the rows only have
Column1, Column2 and Column3
Again I only want to display column1 and column3.
The below code is a sample code that is supposed to display the months in a combobox.
Dim months() As String = _
{"Select a month...",
"January", "February", "March"}

But what am I supposed to do with this code? I have created and named the combobox "cboExpirationMonth", but where do I put this code? I tried to put it as a click event of the combobox, but that doesn't work. I created a button and tried to put the code in the button's click event, but that still doesn't populate the combobox.
