Use a button and set it's image to be the image you want to show.

The below code just provides the ability to change the password:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<asp:ChangePassword ID="ChangePassword1" runat="server"
CancelButtonType="Button"
ChangePasswordButtonType="Button"
ContinueButtonType="Button"> </asp:ChangePassword>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I want to give the user the capability to make almost a full update of his
personal account details which, besides the password, would also
include First Name, Last Name, Email, Adress, City, Country, Zip and
Phone.
Can it be done by including the “ChangePassword” control or it needs
to be done completely in a programmatic way ?
If so what code should I use ?
( I am using C# and Asp.net 2.0 )

Hey guys,
I'm trying to check the uniqueness of the index key of visual foxpro tables. From the tableinfo table I read all names of the tables in the database and the name of their index key.
The name, index key and path (omniwinroot) are stored in an instance of class ActiveTable named tableToAnalyze
Next I invoke a member method of ActiveTable (Analyze.Table) on that instance.
This executes 2 queries on the table. The first one counts all the records, last one counts only those with distinct index key.
If there are less unique index keys then there are rows in the table then the UNunique index keys are safed in a queue (so it could be fixed later).
The goal is to copy (by value) tableToAnalyze to a list of instances of ActiveTable when double index keys were found.
So something like this:
<br />
Class classVar = new Class();<br />
list<Class> classList= new List<Class>();<br />
<br />
classVar.integer1 = 1;<br />
classVar.integer2 = 3;<br />
<br />
if (condition) classList.Add(classVar);<br />
From there i could display in a datagridview and prompt the user to repair (only those tables he wants to repair).
The code I have seems to copy by reference. After all the tables are analyzed my list holds 2 (which is correct) of the same values. Both hold the values of the last table
What am i doing wrong?

Creating a new instance of the ActiveTable variable should do the trick into your while loop
while (readerTableInfo.Read())
{
tableToAnalyze = new AnalyzeTable();
tableToAnalyze.omniwinRoot = omniwinRoot;
tableToAnalyze.table = readerTableInfo.GetString(3).Trim();
tableToAnalyze.tableKey = readerTableInfo.GetString(4).Trim();
tableToAnalyze.AnalyzeTable();
tableToAnalyze.verschil = tableToAnalyze.tableRecords - tableToAnalyze.tableUniqueRecords;
if (tableToAnalyze.verschil > 0)
{
tableToAnalyzeList.Add(tableToAnalyze);
}
}

That did the trick indeed.
I thought about it but couldn't understand why this would help.
Still don't, hoping to come across an answer in the coming days.
(studying c# for work)
Anyway, thanks a lot.

Because you were reassigning the properties of the same instance each time. Thats why you got the same object twice in your list because the object is by reference.
With the modification, you'll create a new instance of the object on each iteration and each object in your list will be different because they point at their own reference.
Hope that help

Yes, that helped

i have two forms ChatManagerForm and ChatWindowForm, and i have a bool variable in ChatManagerForm to indicate that the ChatWindowForm is opened or not.
i want to set this variable to false at ChatWindowForm closing, here i think about two choices.
first: make the variable static,and keep the ChatWindowForm refrence and then
access the variable from the ChatWindowFrom instance.
second: use delegetes and events(pass message from ChatWindowForm to ChatManagerForm).
what is the best, the most practical.
or any other suggestions.
thanks in advance

cant you just use myChatWindowForm.Visible ?
|
|
|
|

I would use a delegate and event.
public delegate ChatWindowClosingHandler(object sender, EventArgs args);
public interface IChatWindowManager {
void ChatWindowClosing(object sender, EventArgs args);
}
public partial class ChatManagerForm : Form, IChatFormsManager{
public event ChatWindowClosingHandler OnChatWindowClosing;
public void ChatWindowClosing(object sender, EventArgs args){
}
public ChatManagerForm(){
InitializeComponent();
this.OnChatWindowClosing += new ChatWindowClosingHandler( ChatWindowClosing );
}
}
public partial class ChatWindowForm : Form {
public ChatWindowForm( IChatFormsManager cfm ){
InitializeComponent();
this.FormClosed += new ChatWindowClosingHandler( cfm.ChatWindowClosing );
}
}
I have not had a chance to test the above code but I've used this design pattern many of times. I guess you've gotten three differnet answers to your question. lol. I hope this is helpful.
I'm listening but I only speak GEEK.

The use of the definite article implies that we know what you are talking about. We don't.
What, exactly, do you want to do? And what part of that are you needing help with?

He's posted elsewhere and seems coherent... I think he's just drunk. Can we add an item to the posting guidelines that says if you're too drunk to drive you're too drunk to post?

Oh, no, we must welcome that posts:

Where can I find a comprehensive explaination of "How to store images in a Resource File and later get these images programatically?" Are there programs available for working with Resource Files? (I am new to this area of C#)
(Code Examples would be very helpful)

If you are working with Visual Studio 2005 just add a resource file to the project (RESX) and the IDE will let you add whatever resources you need and provide a class to retrieve them for you.
|
|
|
|

Placing images in the resource file is easy, but how do I get to these images programatically?
I am creating controls using code, and based on two loop indexes I know the image file name.
For example: IMAGE0000.JPG, IMAGE0001.JPG, IMAGE0100.JPG, IMAGE0101.JPG to load four images using a loop
For x = 0 to 1
For y = 0 to 2
newPic.image =
<br />
Next y<br />
Next x <br />

I want to retrieve a row from a stored procedure specified by the primary key
how can i do that.... what would be the definition of the stored procedure..
and how would i receive them in my c# code....help needed..
The table contains columns:C_Name,C_Capital,C_Currency,C_President of type nchar.
Thanks..
Regards,
Mujz..

I would recommend buying a book on SQL and reading through it. The ADO.NET stuff you can probably get from the web. What you're asking for is the first example anyone is likely to learn in SQL, and it's
select C_Name, C_Capital, C_Currency, C_President from myTable where primaryKey = x
and x is obviously a parameter to the stored proc.
