Closing and opening button's bacground images by sequential clicks. [modified]

Hi friends,
Briefly, I am working on runtime application. I have 10 buttons with their bacground images.
On first click,I want to see any button's backgrounimages. On second click, I want to
close this background image.

I constucted 10 buttons and gave their bacgound images. Now, When I make first click to the
button, I want to see button's background images. On second click, I want to close this
backgoundimage. I am using one image variable to keep first backgroundimage. The problem is
that, by using one image variable, I can keep only one button's backgrounimage but I have 10
buttons. What can I do to keep all buttons's backgrounimages. I think, using 10 image variables
for 10 buttons isn't right way. Is there any simple and logical way to make this.

Help needed - Extracting data from Excel to Access

hi,

i'm now working on this section of project using c# on visual studio .net

this program is suppose to run the automation process in just one/a few clicks.
It's supposed to extract only 1 column, for example, 'Code' from the ms excel file,

In ms excel...

Name | Number | School
---------------------------------------------
Terry | 1234J | ASchool
Tom | 7654P | CSchool

then insert the column of data into the existing ms access file below.

In ms access...

Code | num | Role
----------------------------------------------
10A | 5678Y | Player
10B | 8765R | Player
10C | 1234J | Player //number inserted into column
10D | 7654P | Player //number inserted into column

i would kindly appreciate if anyone would guide me through this, or point to me any existing solutions.
Poke tongue | ;-P

thanks!

Well, at www.connectionstrings.com you'll find the connection strings needed to connect to both Excel and MS Access. I recommend using OleDB. To extract data from one column from excel just create a query like

SELECT * FROM [Sheet1$A1:A100]

Hope this is a good start for you.

thanks for the fast reply Smile | :)

regarding this

SELECT * FROM [Sheet1$A1:A100]

may i know what it means within the [] brackets? is it the worksheet name? if that's the change, the name is prone to frequent changes. are there any ways i can still extract the data regardless name?

You can get the sheet name using this:

OleDbConnection connection = new OldeDbConnection("...");
DataTable dt = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
//in every row contains a column named "TABLE_NAME" which contains the name of the sheet

You might want to check [this ^] out.

Hope it helps.

Synchronize two scrollbars

Hello...

I habe 2 TreeView. I want to synchronize the scrollbars between that 2 treeView.
So, if I scrolldown the 1 treeView, the 2 treeView will be also scrolldown.

How to do that ?

Thanks...

Handle the scroll event of control 1, and in it, set the scroll pos of control 2.

Hello,

As the TreeView has no "Scroll" event you would have to inherit your own TreeView.
There you have to set up your own Scroll event with the use of the overriden "WndProc" method.

This [^] nice article shows how to do it!

All the best,

Martin

How to: Override function with other function, that already exists? [modified] (Unanswered!)

alex_inside14-Nov-07 22:14

public abstract class Test_setting_date_value_base : My_test_base
{

[Step ("2.INHERITED attribute")]
protected abstract bool s2_custom (object data);
protected abstract bool s7_custom (object data);

protected bool s7_goto_datetime_month_value_and_press_ok_up (object data)
{//do something
}

public override BlaTests.Test_step [] get_steps ()
{
Test_step [] steps =
{
s1_initialise,
s2_custom,
//...
s7_custom,
s12_deactivate
};

return (steps);
}
}

public class Test_setting_date_value_1 : Test_setting_date_value_base
{
protected override bool s2_custom (object data)
{
return set_date (30, 11, 2003);
}

protected override bool s7_custom (object data)
{
return s7_goto_datetime_month_value_and_press_ok_up (data);
}
}

Is it possible to do for a class the function that overrides previous implementation by setting 'pointer to function' like in JavaScript? I.e. I want something like that in second class (Test_setting_date_value_1):

protected new bool s7_custom = s7_goto_datetime_month_value_and_press_ok_up ;

I dont' know, but it somehow connected to keyword delegate.

I mean I want that:

Parent has abstract and ordinary method.
Child overloads abstract method with parent's ordinary second method.

So its like I want to assign to abstract method already existant parent's method (or child's method) in the way something like that:

protected bool s7_custom = s7_goto_datetime_month_value_and_press_ok_up ;
//s7_custom - abstract
//s7_goto_datetime_month_value_and_press_ok_up - already defined in parent (or child)

So if s7_custom() called, then s7_goto_datetime_month_value_and_press_ok_up() is called instead.

Choosing and setting a control's property programatically

14-Nov-07 21:59

Hi all,

Is there a way that I can choose which property of a control to set and then set it, all at runtime?

Let's say I want to set the text on a button at runtime to a string value I read from a file, that's easy. I simply call:
myButton.Text = strMyVal;
The same goes for setting the size, the location or whatever.

However, what if I will only know at runtime which property needs to be set. So I have two variables, strPropertyName and strPropertyValue. How do I set the property of myButton that matches strPropertyName to strPropertyValue?

I was hoping for something like:
myButton.PropertyByName(strPropertyName) = strPropertyValue;
but to my knowledge there is no such thing as a PropertyByName method.

Any other ideas?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
