I use Vb.NET from VS 2010 I use a SQL File to run a script, when changes to the database should be done.This works fine for me. The SQL File is in my project and marked as embedded file.Now I run into an issue. I have to change the user name, when updating a Trigger or SP (for complete information: I use mySQL and 3rd Party Script component)So, I thought, I write the embedded file into a Temp-File, make the changes to the file, run the temp file through the script component and then delete the file.

I have been trying to work out how to change the content of a picture box using a context menu. The idea is that the user would have a choice of three images which are saved in the resources file to change the main picture on the form. Is this possible?
These are the few options that I have tried from looking around on the net:
Private Sub ButtonImage1ToolStripMenuItem_Click
(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles ButtonImage1ToolStripMenuItem.Click
PictureBox1 = (My.Resources.button1)
End Sub
[Code] .....
None of these have actually worked.
I am using the FormLayoutPanel for the first time and I am not able to figure out what is going on.On the form, I have a label that can grow and shrink because the content can change. The text includes the name of the client and that name can always be different lengths in regard to characters. I also have a grid on the form.
As you will see from the attached image, the form that has the FormLayoutPanel on it is showing small and not showing the content of the form. The form is indicated via the green arrow.In regard to the FormLayoutPanel, I have set it up in the following way:
Three rows, one column.The label is in the first cell, nothing in the second cell and the grid in the third cell.The TableLayoutPanel is anchored top, left, bottom, right.
Autosize = True
AutoSizeMode = GrowAndShrink
The Label in the first cell is anchored top, left, bottom, right TextAlignment = MiddleLeft
The grid in the third cell is anchored top, left, bottom, right and also Dock = Fill

I have to do some maintenance on an old VB.NET application (Visual Studio 2003) that uses Infragistics NetAdvantage 2006. I have a UltraCombo control binded to a DataView.

I have a ComboBox which content might change. The issue is when the content is changed, 1) i lose the previous selectedIndex, and 2) SelectedIndex is set to -1. I would like an MVVM solution, not some solution involving code-behind. I can have the SelectedIndex set to 0 on content change, but -1 is not a valid value for my model.
What i did as a 'trick' was to have the setter of the property bound to SelectedIndex to set the value to 0 when the value is set to -1. So now i don't have incorrect value in my model. But the ComboBox does not display the "0"th item, rather an empty box.
What could i do to have my ComboBox display the first item (index 0) when its content changes ?

I want to be able to hide the left hand side of the screen and right hand side of the screen at the beginning of the program.
Then when the user presses create new button the left hand side of the screen becomes available so they can create the new item. Then when they press save it comes back to the middle datagrid only.
Then I want to add an event when the double click on the datagrid row (data is programmed in to the datagrid in the code) the right hand side of the screen becomes visible then when the button allocate is pressed the right hand side disappears again just leaving the datagrid.

View 4 RepliesI have a WPF RichTextBox which contain in its FlowDocument both text and images. I need to iterate through the text's words (those which builds the text which the user see on the screen) and change their content and formatting. For instance, change the word "room" to the word "home", applying to the last a red color.
I need to change words whether they are formatted or unformatted.For instance, if a word is in Italic, colored, or just regular black text, it makes no difference for me.Each word will be replaced with one which have about identical length, so I don't want that this operation will effect the general page layout. All images and other objects should remain at their positions.It is preferred that the process of this operation will not be visible to the user. Only its result should be visible (i.e, no visible selections of text).If this operation can be done either directly on the FlowDocumet or with properties/methods of the RichTextBox, the simple one is preferred (but exmaples for both will be ideal).

View 2 RepliesI'm using VB 2008 and windows vista. I'm using a listview in my application.(view=details) I assign an image list to listview.smallimagelist. when user try to sort the listview by clicking the column header i use the imageindex property to set an icon for that column header, this works fine. When user clicks another column to sort the listview by that, I use listview.columns(PreviousColumnIndex).imageindex=-1 to remove the sort order icon from the previously selected columnheader, but it does not remove the picture from the previous columnheader. How should I remove the icon(picture) from the previous column header?
View 7 Repliesi got a DataGridView with a various number of columns, depending on the user's selection.
My problem is that if I want to print the DataGridView, it does not fit on one page
How can the column header be printed vertically?
Has anyone an idea (or better) a code-snippet?
After a long time searching, I am still facing an issue with my listview column header I am trying to add a sort indicator (a small 16x16 arrow, next to the column title - looks quite good).
- My listview is in Ownerdraw mode for : Items & Subitems for a couple of reasons
- So far, I was letting the system do the job for the header (e.drawdefault = true)
I managed to add very easily the arrow using the e.graphics class, right after the e.drawdefault=true, and it is actually working good.
print01.gif
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, 34, 2, 16, 16)
As you can see, I'm simply using a resource, and am forcing it to 16x16 with a custom location x=34 pixels y=2pixels My issue comes with the following :
(Sub ColumnHeader OwnerDraw)
e.DrawDefault = True
e.Graphics.DrawImage(My.Resources.fleche_v2_16x16, (e.Bounds.X + 34), 2, 16, 16)
The arrow wont draw Of course the sort indicator will sometime be on the 2nd column etc.. That's why I need to use the column header's bounds.I can already hear you saying : if you do not owner draw, you can't..But why is it working with a static location (, 34, 2, 16, 16) ans not starting from another static location (e.bounds.x) How can I fix that ? I cant find previous issues similar to that one over the internet.
Points of interest :
- I tryed to load the int value e.bounds.x into a variable before, using that instead of e.bounds.x but it's all the same.
- Using the imagelist is not an option, As you can tell from the screenshot, I am already using images for headers.. the sort indicator is coming as another image
- Using ">" or "<" in the header's text is not an option either........ (sorry pal It does not look good at all..)
- Drawing the header totally in owner draw mode would be an option, but it looks quite hard to do (need to manage the "rounded" header style of the system, the mouse over - small yellow line rounded on the sides in WinXp, the click effect....).
