Hi everyone,
Know of any vertical progress bar for .NET or how to create one? Any help is good. Thanks.
It is not the length of time, but what you plan to do with the time given to you that matters.

i have 3 forms 1 is MDIContainer that is mdiparent and remaining 2 are chiles i.e. Child1,Child2
if i want to open childs in mdi i have to write in mdiparent
Child1 obj = new Child1();
obj.Show();
obj.MdiParent = this;
suppose is want to open Clild2 on click of button on child1
so i have to write code
Child2 obj = new Child2();
obj.Show();
but it open in new it doesn't have any parent
i want that it open in mdiparent as a child
so i try
Child2 obj = new Child2();
obj.Show();
midparent par = new mdiparent()
obj.MdiParent = par;
but it is not possible to create object and specify child2 to mdiparent is mdiparent
any another way
please post as early as possible
thank you

If child1 was created as an MDI child, then it's MDIParent property can be used.
In your Child2 code, you should be able to do the following:
Child3 frm3 = new Child3();
frm3.MdiParent = this.MdiParent;
frm3.Show();
Cheers,
Simon

What is the way to deactivate the keyboard while my richTextBox is being updated?
|
|
|
|
|
While there are a few ways ranging from overriding ProcessDialogKey and doing nothing while a state variable is set to P/Invoking SetWindowsHookEx and writing an extremely efficient and robust keyboard hook, the most simple way is to set RichTextBox.Enabled to false. The point of disabling a control is to disable input into that control.

The ValueChanged event of the NumericUpDown control is not fired when the user changes its value, by typing in the text part of it;
Though it should be, as documented in MSDN.
(it is only fired when the user clicks the up and down arrows)
How can I make it to be fired?

It should be fired when the control loses focus. Until the control loses focus the value is not actually changed when editing it manually. If this wasn't the case, if you mean to type 90 and the event fired when you typed just 9, bad things could happen that the developers using the control may not expect.
If this is the behavior you want, try extending the control and overriding ProcessDialogKey or ProcessDialogChar and fire the event yourself, or use a timer to fire the event after a short amount of time (enough to give moderately slow typers time to enter 2 or more digits - whatever it is you're expecting).

sorry for posting again :
if its web based then try this ..
//client side code ...
function ValidateNum(input,event){
var keyCode = event.which ? event.which : event.keyCode;
if(parseInt(keyCode)>=48 && parseInt(keyCode)<=57){
return true;
}
return false;
}
at server side page load event
write
yourtextboxname.Attributes.Add("onKeyPress","return ValidateNum(this,event)");

Handle the KeyPress event and set KeyPressEventArg's Handled property to true if the character is non-numeric.

Just as Font.Height property gets the line spacing, in pixels, of the given font, how to calculate the same when we have an image instead of a text between two lines.
i.e if we insert an image in any document one after another in consecutive lines there is some space between two images. How to get that value ?
---------------------------------------- line 1
(^o^)/ my image
---------------------------------------- line 2
please guide

here is what I have:
<br />
private frmMain ParentForm<br />
{<br />
get{return (frmMain)this.MdiParent;}<br />
}<br />
<br />
private void frmEventList_Load(object sender, System.EventArgs e)<br />
{<br />
ParentForm.StatusBar = "Searching for events";
LookupEvents(DateTime.Now, DateTime.Now);<br />
ParentForm.StatusBar = "Ready222";<br />
}<br />
using this the Parent forms status bar text does not change. No exception is thrown indiciating that there is somthing wrong with the code. I have just recently had to change over from VB.NEt so it may be something simple.
Thanks for the help

are u sure ur frmEventList_Load is getting callled? Try putting a break point in the event handler and following ur code. U should see where ur code is failing to do what u expect. What u've posted looks fine but we're missing a lot more that could be wrong.

I have put the line break in the load event. It steps through fine, but when I call on the StatusBar property in the commend window it says:
error: 'ParentForm.StatusBar' does not exist
but how would the parent mdiForm not exist? Thanks for the help.
|
|
|
|
|
Could you please post the code where u are creating and showing the MdiChild?
|
|
|
|

Here is the form load for the mdiParent
<br />
private void frmMain_Load(object sender, System.EventArgs e)<br />
{<br />
StatusBarPanel status = new StatusBarPanel();<br />
status.AutoSize = StatusBarPanelAutoSize.Spring;<br />
sbrStatus.Panels.Add(status);<br />
sbrStatus.ShowPanels = true;<br />
<br />
Form frmEventList = new frmEventList();<br />
frmEventList.MdiParent = this;<br />
frmEventList.WindowState = System.Windows.Forms.FormWindowState.Maximized;<br />
frmEventList.Show();<br />
}<br />
Thanks for the help

I cant see what is wrong with ur code...at least not to the point where the command line would give u the error ur stating, unless ur querying ParentForm.StatusBar when its out of scope although I doubt that. Whats even wierder is that, if I'm not misunderstanding, when ur application runs, your not getting any exception.
Just to cover all possibilities, I'll ask u to post some more code once again...sorry :p :
Please post ur StatusBar property.

I have a windows form, with a data grid on it, that contains information pulled from an xml file. I want to be able to detect if anything in the datagrid is edited, but I do not know what the event is called. Thus, if they add a row, edit a cell, or delete a row, I will set a bool variable (isChanged = true). Any help on what the event is called or how this can be acomplished will be appreciated. Thank you.

you can iterate through the cells and check a property for which ones have changed. It's not an event though, I found I had to have a 'save' button when I did something like that, then checked the cells for changes.

Do you read the contents from the XML file into a DataTable and set that DataTable as the data source for the DataGrid? If so, the DataTable has a RowChanged event that will be useful.

 Hi everybody!
Maybe there is somebody who can give me a bit of help; I am about to give up:
I need to ‘translate’ in C# the function GetOpenFileName to include a FileOpenDlg in a Dlg template containing other components, but I cannot handle in C# the reference to the Dialog template resource and the call back function.
Below is the code:
[ StructLayout( LayoutKind.Sequential, CharSet=CharSet.Auto )]
public class OpenFileName
{
public int structSize=0;
public IntPtr dlgOwner= IntPtr.Zero;
public IntPtr hInstance=IntPtr.Zero;
public String filter = null;
public String Customfilter= null;
public int maxCustFilter=0;
public int filterIndex=0;
public String file= null;
public int maxFile = 0;
public String fileTitle= null;
public int maxFileTitle= 0;
public String initialDir= null;
public String title = null;
public int flags=0;
public Int16 fileOffset=0;
public Int16 fileExtension=0;
public String defExt= null;
public IntPtr custData=IntPtr.Zero;
public IntPtr fnHook= IntPtr.Zero;
public OFNHookProc fnHook= IntPtr.Zero;
public String TemplateName;//=null;
}
[ DllImport( "Comdlg32.dll", CharSet=CharSet.Auto )]
public static extern bool GetOpenFileName([ In, Out ] OpenFileName ofn );
……..
…….
private void cmdOpenClick(object sender, System.EventArgs e)
{
OpenFileName ofn=new OpenFileName();
ofn.structSize=Marshal.SizeOf(ofn);
ofn.dlgOwner= this.Handle;
ofn.hInstance=IntPtr.Zero;
ofn.filter="Eseguibili (*.exe)\0*.exe\0Text Files (*.txt;*.doc;*.wri)\0*.txt;*.doc;*.wri\0Tutti (*.*)\0*.*\0\0";;
ofn.Customfilter = null;
ofn.maxCustFilter=0;
ofn.filterIndex=0;
ofn.file=new String(new char[_MaxPath]);
ofn.maxFile=ofn.file.Length;
ofn.fileTitle=new String(new char[_MaxFile]);
ofn.maxFileTitle=ofn.fileTitle.Length;
ofn.initialDir="C:\\";
ofn.title="Apri un file";
ofn.flags= OFN_EXPLORER|OFN_ENABLETEMPLATE|OFN_ENABLEHOOK;
ofn.fileOffset=0;
ofn.fileExtension=0;
ofn.defExt= null;
ofn.custData=IntPtr.Zero;
ofn.fnHook=??????????????????????????;
ofn.TemplateName=????????????????????;
bool risp=GetOpenFileName(ofn);
}
Any pretty good ideas? Many tanks in advance!!
