hi all,
i have 2 buttons on a simple form.
both do different things.
but i want button2 to be treated as if its clicked if i click on button1.
how can i do this ?
|
|
|
|
|
what i got is you want to click the button 2 when u click button 1 if its the case
then just call button two click event on the button1 click event
private void button1_click(Object Sender, Args e )
{
Button2_click(sender, e);
}
in heading you are saying enabling for enable u can use the property
button1.enabled=true or false.
hope this will help you.

What do you want exactly?
If you want to enable a button, just call button2.Enabled = true, where button2 is your button variable.
If you want to call the same code for button 1 and 2, just do something like this:
private void button1_Click(object sender, EventArgs e)
{
button2_Click(sender, e);
}
and vice versa.

or
private void button1_Clicked(object sender, EventArgs e)
{
button2.PerformClick();
}

One of the simplest ways to do this is to insert a row into the data source that drives your grid. in the button click event, add a new row to your data source (not in the database, in memory) and rebind to the data grid. For example, if you were going to use a DataTable as your source:
DataRow newRow = myTable.NewRow();<br />
<br />
myTable.Rows.InsertAt(newRow,index);<br />
myGrid.DataSource = myTable;<br />
myGrid.DataBind();
This also gives you a placeholder to store the data that is being edited by your data grid (assuming your data grid is being used to edit data). When submitting multiple rows to a database, I will typically submit the data as XML to a stored procedure and then let the stored procedure handle the inserts/updates. This assumes you are using MS SQL, Oracle, or another XML aware data source. If you are not,create a transaction (assuming your data source supports transactions), walk through each row of your data source and perform your insert/update, and commit the transaction.

Hi,
I'm trying to create a new row and add values to the column in the below code.
But it throws exception called "Update unable to find data table 'Table' or Tablemapping 'table' ".
DataSet dset = new DataSet();
SqlCommand dbcommand = new SqlCommand();
dbcommand.CommandText ="select * from DBTable";
dbcommand.Connection = myConnection;
SqlDataAdapter dbDA = new SqlDataAdapter(dbcommand);
dbDA.Fill(dset, "DBTable");
DataTable dbtable = dset.Tables[0];
// dset.Tables.Add(dbtable);
DataRow row;
row = dbtable.NewRow();
row["Name"] = DBfile;
row["Meters"] = IMeter;
dbtable.Rows.Add(row);
dbDA.Update(dset);
any solution? or let me know how to create a new row and assign values to the columns.

How can i add scroll bar to my form?
|
|
|
|
|
Set the forms AutoScroll property true and make the form so small that at least one control is located outside the form's client region.

hi all,
i have a msaccess database with 3 fields 'case', 'dateopened' (day,month), houropened(hour,minute,second) and 'whoopened'.
i have such a data text:
******************** CASE OPENNING RECORDS OF 80 ENTRIES ********************
***************** (MONTH/DAY-HOUR:MINUTE:SECOND-#AUTHORITY) *****************
------------------------------- CASE NO: 9876 -------------------------------
05/12-17:25:05-#3 05/12-17:24:56-#3 05/12-17:24:44-#0 05/12-17:24:32-#3
05/12-17:24:22-#3
---------------------------------- DATA END ---------------------------------
how can i parse this text and get case No and other datas from ?
many thanks in advance.
bye.

Well, it depends on if you can format the text as you want..
If your text is a bit small (something like few kilobytes), and performance is not an issue here you may want to directly use the (IndexOf) function to locate cretain Keywords (eg. "RECORDS OF ", "CASE NO: ", or "DATA END"), also then you may reformat your data text to be something like this:-
[CASEOPENNING] [RECORDSOF] 80 [ENTRIES]
[DATA]
[CASE NO]9876[/CASENUMBER]
05/12-17:25:05-#3[NEWENTRY]05/12-17:24:56-#3[NEWENTRY]05/12-17:24:44-#0[NEWENTRY]05/12-17:24:32-#3
[NEWENTRY]05/12-17:24:22-#3
[CASE NO]6675[/CASENUMBER]
05/12-17:25:05-#3[NEWENTRY]05/12-17:24:56-#3[NEWENTRY]05/12-17:24:44-#0[NEWENTRY]05/12-17:24:32-#3
[NEWENTRY]05/12-17:24:22-#3
[/DATA]
where you can look to for the index of "[NEWENTRY]".
Then it's easy!!
If your text data is a bit large & you want to boost the performance you may want to try the "ReadLine" function to read your text line by line. Then in the read text parse it with (IndexOf) in a way similar to the above.
There are many other ways to parse and format any text. This was merely a suggestion , Good luck.

I use this code (MSDN):
System.Net.WebRequest request = System.Net.WebRequest.Create("http://.../name.ico");
System.Net.WebResponse response = request.GetResponse();
System.IO.Stream responseStream =
response.GetResponseStream();
Bitmap bitmap2 = new Bitmap(responseStream);
PictureBox1.Image = bitmap2;
this code show image 48x48.
but i need show 16x16x24b.
How to do this?
Please help me!

Hi,
haven't tested it but you could try:
Icon icon = new Icon(responseStream, 16, 16);
Bitmap bitmap2 = icon.ToBitmap();
This should give you an Icon with 16x16 size but I don't know which color depth will be used...
Probably looking at MSDN[^] would also be a good idea.

I write next code:
System.Net.WebRequest request = System.Net.WebRequest.Create("http://microsoft.com/favicon.ico"); this image is Ok!
System.Net.WebResponse response = request.GetResponse();
System.IO.Stream responseStream = response.GetResponseStream();
Icon icon = new Icon(responseStream, 16, 16);
Bitmap bitmap2 = icon.ToBitmap();
TabPage1.Image = bitmap2;
it is don't work
in this line error
Icon icon = new Icon(responseStream, 16, 16); ->This stream does not support seek operations.
but:
Icon icon3 = new Icon("D:/Program Files/EasyPHP1-8/www/e107n/favicon.ico", 16, 16);
Bitmap bitmap3 = icon3.ToBitmap();
TabPage2.Image = bitmap3;
is work (16, 16: Ok)
how to fix this problem?
I need load image from Internet.

You should try loading the whole response into a byte array (GetBytes), create a new MemoryStream with these bytes and use this stream in the Icon constructor. The MemoryStream should be capable of doing seek operations.

Hi,
I need to hit-test a graphicspath object, the path could have had any number of transformations applied to it. For example, I've added a rectangle (X=50, Y=50, W=200, H=200) to the path, it's been rotated at 45degrees. Now, while it draws correctly, the hit-testing (GraphicsPath.IsVisible) doesn't seem to work with the rotation, if the path hasn't had any transformations applied, the hit-testing works perfectly (the same as Rectangle.Contains it would appear), but when it's transformed...nadda. Doesn't work.
Thanks in advance for any light you may be able to shed!
