Well, maintain your position / index in the array; don't start searching for the page "you know you are already on".
Based on your scenario, your "index" should be 4 (i.e. the last "10") and you know you can't move "next" because the "count" of the items in the array is not greater than index + 1 (using 0 based addressing).
Moving to a new page directly, you simply add that page number to the end of the array, and set the current index to that entry.
Moving "previous", decrement the index; until it reaches 0, at which point you know you're at the first page visited.

search CP articles about "history" or "undo/redo". There is at least one very good one I remember.

Hi
I am trying to insert a DataGridViewComboBoxColumn, the column is getting inserted but without values (options) in the combobox.
The Code is as under
<br />
DataGridViewComboBoxColumn column = new DataGridViewComboBoxColumn();<br />
column.HeaderText = "SELECT";<br />
column.Name = "ItemSelect";<br />
column.CellTemplate = new DataGridViewComboBoxCell();<br />
column.Items.AddRange("One", "Two", "Three");<br />
column.DropDownWidth = 160;<br />
column.Width = 90;<br />
column.MaxDropDownItems = 3;<br />
column.FlatStyle = FlatStyle.Flat;<br />
myDataViewGrid.Columns.Insert(0, column);<br />
When I run the code, in datagridview all cells except 1st are populated properly, in first cell I see only empty combobox.
Also, after showing the value, which event should I use to get the selected value of combobox?
Please guide
Thanks in advance

Yes you are missing something. You would be way better off posting your question here[^] since he more likely to see it there than here. And posting a question about a VB article in the C# forum is almost certainly not going to get you an answer.
Why is common sense not common?

My C# program is set to target the 2.0 version of the .NET Framework.
I used one of the overloads of WaitHandle.WaitAny that's only available in the 3.0 version of the framework, and it let me build the program and run it!
Is this supposed to occur?
The problem is that when I run the program on a machine that only has version 2.0 of the framework, the program crashes, of course.
But why did Visual Studio allow me to use an overload from the 3.0 version when it shouldn't have?
|

|

Actually 3.0 is a update to 2.0. It runs over 2.0. Thus if you build your project with a machine which have 3.0 installed, it will automatically take it as 3.0 (if not specified explicitly while creating project in VS 2008 IDE).
The project you built has taken 3.0 framework.Thus it requires it when running to a machine having 2.0 and crashes.
3.0 is not a new framework, but just an enhancement to 2.0.

Is there an API for the Win32 CreateProcess interface with all functionality available in C#/.NET?
I'm seeking for an example and would be very grateful for one.
|
|

|

You're either going to use the Process class in the System.Diagnostics namespace or you can P/Invoke the CreateProcess function yourself. Go to http://www.pinvoke.net[^] for details.

|
|
Have a try:
using system.diagnostics;
process.start("excel.exe");

Hi
i have treeview and it has some parantnode and chilenode;
i want when user checked(select) parantnode all of that chilnode's checked automatically;
what should i do?
|
|
|
|
|
If a parent node is clicked, you'll have to write code to enumerate all of its child nodes and check them.
|
|
|
|
|
I would implement an event handler for the AfterCheck event of the TreeView : in that event handler : if the checked Node has child Nodes : call a recursive function passing the TreeNodeCollection of the Node to the recursive function which will check all the child nodes, or do whatever else you want to do.
best, Bill

You need everything from us. Why dont you post this in Job section to get someone do this for you.
Pay people, they will work for you. This forum is to help people. If you have specific help(at least after trying) there are lots of experts who are willing to help.
This way, no one going to help you.

What are you trying to achieve here ? If you need these things, then you should just buy them. If you've accepted a project to write this stuff, then you deserve what you get, if you have no idea how to do them.

Hi.
By drag-and-dropping a file or folder to my application icon I start the application with respect to the dropped file/folder passed in as argument. Dropping on a shortcut to my application (created using right-click) works fine as well, but when I create a icon in the VS Setup Project it no longer features drop.
Do you have any idea as to why icons created by a VS Setup Project (MSI) behaves differentially from icons created by me using right-click?
Best regards,
Disore

I do not know if this is a correct forum, but here goes. I am using XML as a config file. The app will be Opensource. I am currently using XML to store a password in PLAIN text. Is there a whay to Encrypt a password in a whay that it is hard to get actual password. Or shoud i leave it in Plain Text?
|
|
|
|
|
It is never a good idea to store a password in plain text. Best is to Encrypt the password and store the encrypted value.
Excellence is doing ordinary things extraordinarily well.
|
|
|
|
|
Even if it is Open Source?
What kind of key shoud Should i use? Use Profile ID or PC Fingerprint?
Witch encryption method do you sugest?
|
|
|
|
|
You can prompt the user for a "master" password that you use to encrypt/decrypt the stored passwords.
|
|
|
|
|
Whell it seems i woud have to do with a user typed password. I will add for a user to chose how to store a password.
