Is it possible to backup and restore a MySql Database using C#?
How? Any suggestions?
|
|
|
|
|
Yes, it's possible: Get all tables, foreach table, get all columns and then create the script that will add this table into a Mysql database
|
|
|
|

This is somewhat confusing. Could you give me more specifics on what you're suggesting? Are you saying that I backup the database by placing it on another database?
I was thinking more around the grounds of backing up my database on a *.sql file and restoring it from a *.sql file using C#.

|
|
|
|
No, I was saying that you should create the sql script by yourself analyzing the structure of the current database

Ohhh... Hmm... Interesting... Thanks.

Hi,
does anyone knows how to ge the size (area value) of an inregular shape in a bitmap image.
i have a bitmap image with a black background and the shape is all in white, i wonna get the size of the shape and say yes if the shape has rugged edges or no if its more like a circle.
I appreciate any help.

You could look at my image processing articles for info on direct pixel access, then you could walk the image and see if it has straight edges.

Now, I'm very curious, did you actually find that function name (sig) in a real life application, or it's just a sig?

It was a method in code someone posted here asking for help.

string hex3 = "025";
int code = Convert.ToInt32(hex,16);
int code1 = Convert.ToInt32(hex1,16);
int code2 = Convert.ToInt32(hex2,16);
int code3 = Convert.ToInt32(hex3, 16);
richTextBox1.Text = Encoding.Default.GetString(new byte[] {(byte)code,(byte)code1,(byte)code2,(byte)code3});
Now i need arrange all the ascii char in correct position.I hd tried in many ways,but still got errors.pls help me.

Hi guys,
I feel like stupid, anyway. I have a very common question and please no utfg answers, I've done that.
I'm no able to create a control that can accept dragged items from other windows (e.g. files dragged from windows explorer or icons from desktop). I'm using .NET 2.0 and Vista. Is it just something small that I'm doing wrong?
here is what I'm doing.
- create custom control derived from System.Windows.Control class
- make sure the AllowDrop property is set to true
- override OnDragEnter, OnDragDrop, OnDragOver etc...
my problem is that those events OnDrag... never get raised when dragging anything above my application window/control.

I thought you need to also specify in code what file types you accept being dragged ?

Hi,
i'm trying to filter data withe The Binding Source
the thing is that i have a cloumn that is Set as
DateTime Type.
Now i'd like to Filter Monthly Like : "04/2008"
the Thing is that i've got a DateTimePicker that is in the same Format but i don't know what to put in the Filter
i Started with :
BS_WorkingHours.Filter = "(Date > '" + MinDate + "') AND (Date < '" + MaxDate + "')";
Where MinDate Day is Set To "01" + Current Month and Year And MaxDate is Set To "31" + Current Month and Year
they are Both strings
it Does not Accpet String for Compare so i'll need to Put
The DateTime Object itsef, but the DateTimePicker Value Includs
The Day Which in this case i do not need
AnyOne, THANKS 
Have Fun
Never forget it

Of course it does. You are assigning a string to the Filter property. A string can not contain anything but characters.
You can create DateTime values from the year and month values:
DateTime minDate = new DateTime(selectedDate.Year, selectedDate.Month, 1);
Using 31 for date doesn't work well, as all months doesn't have 31 days. Add a month to the startdate, then subtract one day to get to the last day of the month:
DateTime maxDate = minDate.AddMonths(1).AddDays(-1);
Now you can format the dates into strings and concatenate into the filter expression.
Despite everything, the person most likely to be fooling you next is yourself.

Is there any way that I can let the user enter a new record through a form and then add that record dynamically to a combobox (while user types), and give a new primary key to that new record?
Thanks
|
|
|
|

Well to give the user the ability to add to the combobox:
Textbox tbxText=new Textbox
tbxText.tex='insert user input; could be already created if on the form
Combobox cbxCombo=new Combobox
cbxCombo.Items.Add(tbxText.text)
This is pseudocode and not syntactically correct C# code.

Thanks so much, that's exactly what I needed

Hi,
(condition ? result_if_true : result_if_false)
represents a value...
Console.WriteLine(x > y ? "X bigger" : "Y bigger (or equal to)");
is what you're looking for (note that if x > y is false... it doesn't necessarily mean that y > x).
Hope this helps.

Hi Matthew,
Thanks for the reply.
I should be dumb .I forgot the thing." Assignment of result"
Any way thanks for your time
Thanks

Yuo are calling the WriteLine method of Console which is not an:
Laddie wrote: assignment,call,increment, decrement, and new object expressions
Try:
if (x > y)
{
Console.WriteLine("x is greater");
}
else
{
Console.WriteLine("y is greater");
}
You always pass failure on the way to success.

Can I create a subform in C#
In other words, can I put a form as a control on another form (like MS Access)
Mohammed Gouda

Hi,
yes.
a form of the same app is easy: see the Form.TopLevel property.
a toplevel window of another process is more difficult; I don't recall the details; you'll need
the window handle and call some win32 function. It has been discussed on one of the CP forums
some days ago.
