I have a dialog form and appears on the top of MDIContainer (frmMain)
and I want when the user close the dialog form then an MDIChild should
be open on the frmMain. I tried:
myMDIChild.MdiParent = frmMain();
myMDIChild.Show();
but it didn't work.. I also tried:
frmMain MainForm = new frmMain();
myMDIChild.MdiParent = MainForm;
myMDIChild.Show();
with no luck. I am not getting any error message but the MDIChild form
is not openning..
Many Thanks,
Jassim Rahma

Hi,
In the parent window do the following:
myMDIChild.MdiParent=this;
MDIChild.Show();
This code has to be called in the frmMain() class.

|

but the container is not (this).. i am running this code from frmNew() but the mdi container is frmMain()
|
|
|
|
|
in that case, set the IsMdiContainer to true and set the MdiParent property of the myMDIChild class to the new created form.
This should work.
Fred.

let me understand..
my main form is frmMain
my child form is frmChild
the active dialog is frmDialog
a user clicked a button which shows a frmDialog and when the user click on the button on the frmDialog it should close it and open frmChild within the container (frmMain)
so you want to say in frmDialog i should have this:
frmData frmChild = new frmData();
frmChild.MdiParent = frmMain();
frmChild.Show();
I tried that but getting this error:
dialog_form.cs(258): 'Ezi_Life.frmMain' denotes a 'class' which is not valid in the given context

Is this what you're looking for?
in MDI main form:
private void menuItem1_Click(object sender, System.EventArgs e)
{
DialogForm aDialogFormGUI = new DialogForm();
if (aDialogFormGUI.ShowDialog()== DialogResult.OK)
{
ThirdForm aThirdFormGUI = new ThirdForm();
aThirdFormGUI.MdiParent = this;
aThirdFormGUI.Show();
}
}
On the Dialog form in the Close event or Click;
DialogResult = DialogResult.OK;
Hope this helps.

|
|
yes.. it worked.. than you very much
can i ask one more question please
how can i run one instance of MDIChild so that if the user invoked the same option again it will not open a new MDIChild.. t should just bring the already openned MDIChild to front..
|

Don't know if this is the best way but...
In your MDI Main create a method which passes a temporary Form as a parameter then iterate through all open forms to return the index of the form:
int formIndex = -1;
int i = 0;
foreach (Form cf in this.MDIChildren)
{
// compare the Form you passed with all open Forms
if (passedForm.GetType() == cf.GetType())
{
formIndex = i;
}
i++;
}
Replace the code in the if statement of the dialogresult to:
ThirdForm tempForm = new ThirdForm();
int frmIndex = IndexOfForm(tempForm);
tempForm.Dispose();
// The form is not open
if(frmIndex == -1)
{
ThirdForm ThirdFormGUI = new ThirdForm();
ThirdFormGUI.MdiParent = this;
ThirdFormGUI.Show();
}
// The form is already open
else
{
this.MdiChildren[frmIndex].BringToFront();
}

NNTP is a thing of the past...its kina dead and people who use forums a lot have a hard time opening the browser and navigating to their thread and stuff. So i thought i'd make a forums to NNTP covertor...by using screen scraping to rip data off the webpages and convert them in the NNTP Usenet msgs form. IS it even remotely possible in C#?
|
|
|
|
|
Possible? Yes. But not practical at all. You'd have to write code to interpret each individual site. And if the site changes their web page, you're re-writing your code.
I thought this is what RSS was for...

i get yor point dave but the problem with RSS lies in the fact that i can read the post but i can reply to them or post new ones. It's kind of a one way system.

I agree Daves remarks about the difficulty of generating NNTP data from a webpage. The only practical IMO way to do so would be to work from the backend, the easiest way would probably be to use NNTP as the message store and then build the webversion as an NNTP gateway.
Despite it's age, for high volume sites a good NNTP client is far superior to a webUI. Some of the best ones can approach parity, but are much more dependent on having a high speed, always on, connection which not everyone does.

Hi. I think this part of code help you
public void OnStartupComplete(ref System.Array custom)
{
Word wApp= (Word.Application)applicationObject;
}
So use wApp to get all data, you need

I have an MDIForm and 5 child forms in my project. what i have to do is, during MDI Form's "MdiChildActivate" event I have to set some value to private a variable in my active child form. But when i write a statement like this : this.ActiveMdiChild.childVariableMode="0";
I get an error-"No defination For childVariableMode found in activemdichild". In vb.net i can do this by:

I am using MySqlConnector for .NET (version 1.0.4), I am using the following code for dataAdapter's update command:
this.codeListAdapter = new MySqlDataAdapter(
"SELECT * FROM CodeList", this.myConnection);
MySqlCommand codeListUpdateCmd = new MySqlCommand(
"UPDATE CodeList SET ProviderID=?ProviderID WHERE DestCode='?DestCode'", myConnection);
codeListUpdateCmd.Parameters.Add("?DestCode", MySqlDbType.VarChar, 10, "DestCode");
codeListUpdateCmd.Parameters.Add("?ProviderID", MySqlDbType.Int16,
0, "ProviderID");
codeListAdapter.UpdateCommand = codeListUpdateCmd;
codeList = new DataTable("CodeList");
this.codeListAdapter.Fill(codeList);
and then I am using the following code, (after changing some rows of 'codeList' ofcourse):
codeListAdapter.Update(codeList);
codeList.AcceptChanges();
but it throws the Exception mentioned above, what might be the problem?
The structure of the 'CodeList' table is like this:
+-------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| DestCode | varchar(10) | | PRI | | |
| Destination | varchar(50) | YES | | NULL | |
| ProviderID | int(11) | | MUL | 0 | |
+-------------+-------------+------+-----+---------+-------+
Thanks in advance...

Hello everybody!
I want to print a document out with A4 paper size programmatically. But I don't know how to define the precise paper size in C#. And also, if I don't use the form's location, how can I locate a particular position of the paper? Could anybody help me with this please!
Thanks in advance

This is what I gathered from MSDN in a few minutes:
Choose one of the page sizes from PrinterSettings.PaperSizes collection and put it in the PageSettings.PaperSize property.
---
b { font-weight: normal; }

The prefered method is to allow the user to select the paper size since their needs may change after the application is released. To do this, implement a PageSetupDialog. If A4 is the default paper size for the printer, it will already be set in the dialog. If it is not the default size, I believe you could create a PaperSize object, set it to a PaperKind of A4 in PageSettings before printing (or showing the PageSetupDialog). Check the MSDN documentation on PageSettings[^] and PaperKind Enumeration[^].
To implement PageSetupDialog, you can use this code snip from the MSDN article[^] on PageSetupDialog Class in a print button handler. (Note this code assumes a ListBox named ListBox1 that will display the settings (used to indicate how to get the values after the user clicks OK in the dialog) and a PageSetupDialog named PageSetupDialog1.
PageSetupDialog1.PageSettings = <br />
new System.Drawing.Printing.PageSettings();<br />
<br />
PageSetupDialog1.PrinterSettings = <br />
new System.Drawing.Printing.PrinterSettings();<br />
<br />
PageSetupDialog1.ShowNetwork = false;<br />
<br />
DialogResult result = PageSetupDialog1.ShowDialog();<br />
<br />
if ( result == DialogResult.OK)<br />
{<br />
object[] results = new object[]{ <br />
PageSetupDialog1.PageSettings.Margins, <br />
PageSetupDialog1.PageSettings.PaperSize, <br />
PageSetupDialog1.PageSettings.Landscape, <br />
PageSetupDialog1.PrinterSettings.PrinterName, <br />
PageSetupDialog1.PrinterSettings.PrintRange};<br />
ListBox1.Items.AddRange(results);<br />
}
If this doesn't work for you or give you enough clues, post back and let us know.

If you continue to do the same things you always did,
don't be surprised if you get the same results you always got.

Thanks for your code. But I think what I need is to define the paper size programmatically before the page dialog. Because there is a form need to be filled. For example, if give me a check, I need to fill in the address and customer name information in it, so I need to define the precise position of the address row and customer row in the check, then I put the check into the printer, it will print it. Just like the teller does. Actually it's not a check, what I am doing is a invoice which is A4 size. So another problem is that how can I define the location of the field I need to fill in my program??? Any idea please ?
Thanks very much
