if you want to run it pragmatically then you can use socket programming to do that.

I try to create a form game.
I got up to 30 tiles (images) on that second form and I want to change the tile-image each time you click on it.
But it does it only once.
The possible errors are few.
First, here's part of the form code.
private: System::Void TS11_MCli(System::Object^ sender, System::Windows::Forms::MouseEventArgs^ e) {
Tsn11 = Tsn11 + 1 ;
if (Tsn11 = 0) { this->TS11->Image = Image::FromFile("C:/GamePics/NOTILE.png");}
else {
if (Tsn11 = 1){ this->TS11->Image = Image::FromFile("C:/GamePics/GREEN.png");}
else {
if (Tsn11 = 2){ this->TS11->Image = Image::FromFile("C:/GamePics/GRTRE.png");}
else {
if (Tsn11 = 3){ this->TS11->Image = Image::FromFile("C:/GamePics/ROAD.png");}
else {
if (Tsn11 = 4){ this->TS11->Image = Image::FromFile("C:/GamePics/WALL.png");}
};
};
};
};
};
That is the mouse event click.
Now up in the begining of the form, i get to declare the TS variables (one for each tile).
As it is : Tsn11 = 0;
As for the error facts : The form either reinitialise the variables each time you click, either always...
either the imageclick will operate only once.
Either there is a problem in the If Else statements.
So what is it exactly?
And how do I correct it?

Why have you reposted this question with the same incorrect code? A number of people have explained what is wrong with this code and what needs to be changed. Please try what you have been advised to do rather than merely asking the original question in a different forum.

Dear Sir,
When I use some Netadvantages or Infragistics tools with Visual C++ 2005 Forms,I experience the error Index Out of ..... , but with Visual C# there is no problem.
these tools are used only with C# or what ?

Hi,
I am using a richtextBox to display files.
I have set the RightMargin property to a large value so that the data (> 1500 char approx)is shown in a single line.
Problem i am facing now is that on horizontal scroll to the end of the line the text overlaps making it not readable.
Please let me know how can this problem be fixed?

Thanks in Adv.
I have 10 to 15 different controls placed on a WinForm (Grid,DateTimePicker, TextBox etc).
on form closing i want to check that whether User has done any change means data is changed or not, is their any way to cater this change event of any control , without getting change event of each control.

Not that I know of. Mostly I walk the form (foreach c in controls), and hookup small delegate that sets an "IsDirty" property.

So here's a wierd one.... (sorry for the length, but this needs some 'splainin)
I have a UserControl consisting of a TextBox, a Label, and a CheckBox. I have a ShowCheckBox property like so:
[Browsable(true),
DesignerSerializationVisibility(DesignerSerializationVisibility.Visible),
EditorBrowsable(EditorBrowsableState.Always),
Bindable(true),
Category("Behavior"),
DefaultValue(true)]
public bool ShowCheckBox
{
get
{
return checkbox.Visible;
}
set
{
checkBox.Visible = value;
}
}(If you see any compile errors, ignore them, I'm typing this from memory. The code I actually have does compile).
This UserControl is part of the same project as my application. I can place several instances of these controls on my form and the ShowCheckBox property defaults to true, as it should. So far, so good.
Now the weird part...through a variety of actions (switching tabs on the form, recompiling or running the application, etc.), suddenly my ShowCheckBox properties all get set to false, so I don't see the CheckBox in any of my UserControls in the form's designer! Sure enough, the values are all set to false in InitializeComponent. I then go back and reset the properties to true in the designer, and I see the property settings disappear from InitializeComponent (i.e. the default value is being used). After a little while, it happens again - the values magically get set to false again. I'm thinking this has something to do with the DesignerSerializationVisibility attribute?
Even weirder...usually when something changes in InitializeComponent or in the designer, the change is automatically reflected in the other location. But when I see the property values set to false in InitializeComponent, I still see the property set to true in the designer! I probably spent about an hour or so searching Google and CP, and the only help I really found was in setting the attributes I have above.
Is this a bug in Visual Studio by any chance? Or is there some other attribute I'm missing? I'm using VS 2005 SP1, C#, Windows XP SP3, all the latest updates.
Thanks,
Dybs

Hi Friends,
I am learning .net these days on my own. I have created a small application that gets data from access file. There are multiple rows. in each row i have 8 columns.
first column (Product Name) gets data from table1-column1.
Second column cell (Dia) gets filtered data based on value incolumn 1.
Third column cell gete data based on first and second column.
Fourth column based on 1, 2nd, 3rd. (4th column is no of pieces/kg)
we put raw material value in 5th column.
in 6th Column, we get price per piece
in 7th column, we put selling price.
8th column tells us how much we are making or loosing /kg.
Pretty simple application.
However, i know following limitations of my code
1. its not too optmized. For each drop down, data get retrieved from DB.
2. No of rows are hard coded.
3. Form apearance is not too good.
Can we do it using datagrid or some other means?
Code is at following location
Download code

Ajay

A DataGridView could work; it would save you from creating and positioning your own controls. Alternatively; I'd build a UserControl to represent a single line, and drop a collection of those in a Panel with the AutoScroll property set to true.
Ajay Fresher wrote: its not too optmized. For each drop down, data get retrieved from DB.
The table "MasterList" looks small enough to keep in memory, but the table "QuoteHistory" might grow large.
Is the db local, or is it on a remote computer? If it's local, then it might suffice to review the indexes on the QuoteHistory-table. If it's going to be accessed (read) by more people at the same time, consider switching to SQL Express.

Well, a DataGridView (or a Panel with UserControls) would make it easier to "add" a line to the form. I guess it's pretty hard to make it dynamic if you have to position all your textboxes and combo's in advance. Focus on adding an item (e.g., a DataGridViewRow) on demand (a button_click)

This looks to be a better approach. I will try.

It is just a sample DB. original DB has minimum 50-60 K products. These in turn will have different dias and lengths. This DB will grow big.
QuoteHistory will anyways grow big.

I agree with that. Still, How can i have similar combobox approach with Datagrid? i.e. 1st column will have all distinct product types. When i select this, dia should be only corresponding to type etc etc.

That's possible, with an unbound DataGridViewComboBoxColumn.

Hi
I m creating a window application in vs 2005 & 2.0 .net framework
Where i have 1 form which contains lots of cntrols(textbox,checkbox,combobox,buttons )
& 1 Datagridview which will load all data in database on Form_Load event
as well as there many other database related functions are called on Form_Load event
that's why the form is taking too much time to load
So that's why i want to show a loading Image (Not Progress Bar Control ) to show till the form is completely ready
and then hide the loading image and show form
i think this can be done using Background Worker
but i found its very complicated
is there any other way to do so
