Here is what I have in the collapse treeview
Private Sub TreeView1_BeforeCollapse(ByVal sender As Object, _
ByVal e As System.Windows.Forms.TreeViewCancelEventArgs) Handles TreeView1.BeforeCollapse
e.Node.ImageIndex = 0
e.Node.SelectedImageIndex = 0
End Sub
I load the treeview no problem, C and D drive have the drive icons, if I click plus next to drive C, I get all the folders on drive C (with folder closed icons) If I click the + next to a folder I get the open icon folder, and all the pictures with (picture icons) appear in the Listview.
So far So Good.
The Problem
When I close the pics folder the icon changes to a drive icon? if I then open another folder the pictures that appear in the listview are all over the place, I've figured if I change the ImageIndex numbers in BeforeCollapse then that's the icon that shows when a folder is closed, so I think I need something like
If ImageIndex = 2 then make it 1
If ImageIndex = 0 then keep it 0
and I figure I also need to clear the listview so that it can be repopulated in order
I've gone as far as I can with this and I'm sure the answer is something simple but, like looking for wood in a forest, I seem to be missing the obvious?

This should work to get the right messages. As for the listview, it's indeed a good idea to clear the items collection (not the main clear method on the listview itself).
In conclusion: I don't tihnk you have a problem here

Here's the cure for the listview, placed in Private Sub TreeView1_AfterSelect(By
<br />
' Clear listview and reset view type<br />
ListView1.Clear()<br />
ListView1.View = View.Details<br />
'Create the columns.<br />
With ListView1.Columns<br />
.Add("Name", 120, HorizontalAlignment.Left)<br />
.Add("Ext", 40, HorizontalAlignment.Left)<br />
End With<br />
And the cure for the node icons?
well I just deleted all references to
ImageIndex and SelectedImageIndex
So a good result all round

hi
i want a table in sql server with 1500000 records and i use from datagridview for see them but speed of run it is very low .
please help me

Nobody is going to scroll through that number of records on the screen so you need to give them an interface that allows them to select the records they want and only then retrieve them from the database.

Just think about the quantity of data you are pulling across the network.
Assuming each row was one byte, you have requested 1.5Mb of data. Lets find a more typical example and assume you have an id (4 bytes), an 8 byte column (for a date maybe), a 20 btye column (a name maybe), and a 2 byte column (some code). Total 34 bytes of raw data per row not taking into account any overheads for the transmission of that data. That is a total of 51Mb. That would take a few seconds to pull that off a disk, format it for transmission, transmit it, parse the stream on the client, store it in what ever data structure you are using and then render it on the screen.
You should consider filtering the data so that the resultset is more relevant.

After searching through the Registry a bit, I found a key that controls the paths to each Control Panel icon (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Extended Properties\{305CA226-D286-468e-B848-2B2E8E697B74} 2). So I did a bit research to see if I could manually add my own icons my creating a sub key there, but I didn't find much. I did find something though saying you could only use .cpl files, because otherwise the icons would not show. Is this true? Because TweakUI is an application, not a .cpl. And, is it safe to add icons to the Control Panel by creating a a single Registry key?
Thanks a lot!

I'm able to use the string.replace function. Now I want to report on how many replacements have been made.
The below code makes the correct replacement, but I want to get a little feedback.
Dim strStartString As String = "To*All*The*Girls*I've*Loved*Before"
Dim strDestString As String = txtDestination.Text
strDestString = strStartString.Replace("*", " ")
txtDestination.Text = strDestString
Thanks!

All you'd have to do is use a For statement, then read to each "*".
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

|

|

Sure, that would work. I'm sure that there is also different function that could search for how many "*" exist.
My first preference is to get the count of replacements by the function.

MatrixCoder's method is probably the most common technique and I do not think there is a method that is going to give this to you. If you are intent on pursuing a single method call then try this.
Dim Integer counter=strStartString.Split("*").Length-1
I kind of agree with MatrixC's technique since it is very discriptive of what it is doing.

I am trying to enter values in a text box, which are then checked against the value of a label, then if correct, adding a value of 1 to an integer (10 times over) but i am having to use IF statements to do this so my code is getting hefty. Is there a loop which can be used to reduce the code, it would be a great help.
Cheers

You could try a For statement.

Well, it would help if I could see your current code.

Ok, the current code is like this (i know its amateurish, but it was the only way i could get it working!)
Private Sub txtInput1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtInput1.TextChanged
'If statement to check correct inputted value
If txtInput1.Text = lblLetter1.Text Then
'Letter goes green to signify the entry and being correct
lblLetter1.ForeColor = Color.Green
'Adds 1 to the intScoreAll global value
intScoreAll = intScoreAll + 1
'Else statement if incorrect value is inputted
Else
'Letter goes red to signify the entry and being incorrect
lblLetter1.ForeColor = Color.Red
End If
'Disables the input box to stop cheating
txtInput1.Enabled = False
'Selects the next txtInput box for key entry
txtInput2.Select()
End Sub
|

You should be able to put a for loop around the if-endIf statement. I forgot the exact syntax for VB.NET but it looks like this in VC#.NET.
<br />
for(int i=0;i<10;i++)<br />
{<br />
if(txtInput1.Text==lblLetter1.Text)<br />
{<br />
lblLetter1.ForeColor=Color.Green;<br />
intScoreAll+=1;<br />
}<br />
else <br />
{<br />
lblLetter1.ForeColor=Color.Red;<br />
}<br />
}<br />
txtInput1.Enabled=false;<br />
txtInput2.Select();<br />
Well that is how you would use a for-loop but it may be better for you if you just set up a global counter that is incremented by 1 whenever this method is used and when the value reaches 10 then exit. The loop for you in this method would not necessarily work becuase it would do the for loop on the same text that is in the textbox at one time without new text being entered for every of the ten times.

I don't know how to set up it for picture to insert into the Crystal Report.
Please tell me how to set up Formula Fields on Crystal Report XI.

How do you store and HIDE information (such as passwords) so nobody can find/edit/delete/view them?

I don't. If "nobody"* can find/edit/delete/view some piece of information neither can your program.
By allowing your program access you must be open to the possibility that someone may be able to find/edit/delete/view the information. At this point your strategty must turn to minimising the risk of that happening.
In order to do that you need to know what the information is? why it needs to be hidden? What are legitimate reasons to edit it? What are legitimate reasons to delete it? What are legitimate reasons to view (read) it?
Information can be placed in many places: files, the registry, in a database, as an embedded resource in an assembly.
Information can be hidden by many techniques: encryption, steganography (placing it in highly unusual places, e.g. IP packet headers, in a picture or audio stream)
* Which is an empty set

Never store a password - instead store the one-way encrypted version of the password and test any input against that. (RSA or SGK[^] is a good example)

This can actually be done, and given the nature of the .NET framework, it's not surprising. I am sorry to say, I don't recall how tho ( I've not done it ). What is your intended use ?
