Dear Wasim,
instead of making user control write this code in Paint Event of Form
foreach (Control acontrol in this.Controls)
{
if (acontrol is TextBox)
{
Pen myPen = new Pen(Color.White, 4.0F);
e.Graphics.DrawRectangle(myPen, new Rectangle(acontrol.Bounds.X, acontrol.Bounds.Y, acontrol.Bounds.Width, acontrol.Bounds.Height));
e.Graphics.Dispose();
}
}
hope this will help

as far as i understood that you were saying that textboxes are in groupbox
if yes, then just change this.Controls in this line :
foreach (Control acontrol in this.Controls)
with GroupName
foreach (Control acontrol in <<write group name>>)

Hello, guys!!
I am working with an application that uses a try-catch block inside a DragOver Event handler. The problem is that there is an Argument Exception that occurs when a control is dragged. Technically, it is a circular reference. When this Argument Exception occurs, both controls disappear, and the ArgumentException handler catches the error. The question is, how do I get the Exception handlers to prevent the code from running, thereby preventing the controls from disappearing? Is there a way of trapping the condition that causes the ArgumentException so that the controls would not disappear because of the error?
Here is the code:
private static void _ctrlParent_DragOver(object sender, DragEventArgs e)
{
try
{
if (DragDropHandler.CanDropHere((Control)sender, e.Data))
{
Control cthis = (Control)sender;
CardControl ctrl = (CardControl)DragDropHandler.GetControl(e.Data, true, true);
e.Effect = DragDropEffects.Move;
if (!(ctrl is IDragDropEnabled))
{
return;
}
if (cthis.Name != ctrl.Name)
{
if ((ctrl.HasChildren == false) && (ctrl.blnCardFaceStatus==true)
|| ((ctrl.HasChildren == true) && (ctrl.blnCardFaceStatus=true)))
{
ctrl.Parent.Controls.Remove(ctrl);
ctrl.Parent = cthis;
cthis.Controls.Add(ctrl);
ctrl.BringToFront();
}
else if ((ctrl.HasChildren == true) && (ctrl.blnCardFaceStatus==false)
|| ((ctrl.HasChildren == false) && (ctrl.blnCardFaceStatus=false)))
{
return;
}
}
else
{
return;
}
Point NewLocation = cthis.PointToClient(new Point(e.X, e.Y));
ctrl.Left = NewLocation.X - dragPoint.X;
ctrl.Top = NewLocation.Y - dragPoint.Y;
}
else
{
e.Effect = DragDropEffects.None;
}
}
catch (System.ArgumentException)
{
MessageBox.Show("Argument Exception Error");
}
}

Hi everyone...A newbie is confuse here, so please help...and before we start, please aplogize for my bad english 
OK, lets start.
I have a task to make an XML file from unusual Excel file...i'm giving the screenshot...please follow the link
http://img227.imageshack.us/img227/1637/capthd0.jpg
So, as u can see that the spreadsheet is not a good looking one...and i've been trying to convert it into an XML file....with reading many tutors...
The file (.xls) is different in the field name (such as "TMPT LHR" can be "TMPT_LHR" or "TMPTLHR" in other xls file) between another...and it is make me crazy doing for one single file...not yet another file :P
Here are methods that i tried:
1. with XML Schema in the Excel view source...not really good at it (my kowledge), cause my test went bad, the XML file output doesn't go as i wish, it messy..
2. Save As the spreadsheet as CSV, and i found it like this...please follow the link...it more make me confuse..
http://img84.imageshack.us/img84/8210/csvfj3.jpg
3. Save As the spreadsheet as Text, and dont get any idea how to convert it...
4. Save As the spreadsheet as XML Spreadsheet, and i try to read the <data> tag/node in it and finally succeded reading the element string (inside the <data>) using VC#... and try to make a well formed XML file...this part not done yet...
This is the code..

//public String[] strNodeValues15b = new String[15] { "", "", "", "", "", "", "", "", "", "", "", "", "", "", "" }; <- wish this line to held the 15 data of 1 record, that can be not just one record...see pict above please...

Method 3 is probably the best, i.e. saving the spreadsheet as an XML Spreadsheet and then transforming it into the required form. Note that there is a special language design to do exactly this: XSLT.
Some tips for Xml with .NET, take a look into them:
1) There is a whole namespace dedicated to reading, writing and manipulating Xml, the System.Xml namespace.
2) There is (in .NET 3.0 / 3.5) a "query" language (other than XPath) for selecting Xml: LINQ (System.Xml.Linq)

There's a simpler way than those you listed and you won't have to save the Excel file in another format. You can use ADO.NET to read from the Excel file (use OleDb), next you fill the data in a dataset then save the data in the dataset as an .xml file using WriteXml() (you have the option to save the schema too or you could save the schema in a separate file using WriteXmlSchema())
Tell me if you want the details.

Just to put in my two cents – there is a free editor out there that can edit those ado.net xml file. Just drag the file in and it leats you view and edit all the data in a really effective way: (then save it as Excel file.. optionally selecting which rows you'd like to be in that fie)

Hi all, I'm looking for a way to hide a property from the property grid while still allowing it to be serialized into XML. The problem is that if I set the [Browseable(false)] attribute on the property, this hides it from the property grid but also makes the property not serialize out to XML. Is there a decent way around this issue?
|
|
|
|
|
Did you put a XmlElement on the property?
|
|
|
|
|
Yes, but if Browseable is set to false, it doesn't serialize out to XML. So what I need is a way to hide a property from the property grid without using the browseable attribute, or a way to change the browseable attribute dynamically before the item is saved..
|
|
|
|
|
Not sure why Browseable affect serialization... but well..
Some idea, overwrite attribute before you serialize or deserialize. May not work as the property wasn't set to Ignore.
XmlAttributeOverrides[^]
Another way is to use an interface for the property grid, where unwanted property are left out in the interface.

Hi,
i'vw copied some of MS code form msdn about how to print
but it always prints 2 pages only and BLANK
WHAT is going on
this is the code
<br />
<br />
private void printToolStripMenuItem_Click(object sender, EventArgs e)<br />
{<br />
ofdScenario.Filter = "Text Files|*.txt";<br />
if (ofdScenario.ShowDialog() == DialogResult.OK)<br />
{<br />
if (ofdScenario.FileName != "")<br />
{<br />
try<br />
{<br />
prntDoc.DocumentName = ofdScenario.FileName;<br />
srAppUtility = new StreamReader(prntDoc.DocumentName);<br />
prntPreview.Document = prntDoc;<br />
prntPreview.ShowDialog();<br />
prntDoc.Print();<br />
}<br />
catch (Exception E)<br />
{<br />
MessageBox.Show("printToolStripMenuItem_Click");<br />
MessageBox.Show("Error Occured while Printing \nError Message :" +<br />
E.Message, "Print Error", MessageBoxButtons.OK, MessageBoxIcon.Error);<br />
}<br />
finally<br />
{<br />
<br />
srAppUtility.Close();<br />
}<br />
<br />
}<br />
}<br />
}<br />
private void prntDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)<br />
{<br />
#region Inner Defenitions<br />
<br />
float linesPerPage = 0;<br />
float yPos = 0;<br />
int count = 0;<br />
float leftMargin = e.MarginBounds.Left;<br />
float topMargin = e.MarginBounds.Top;<br />
string line = null;<br />
<br />
#endregion<br />
<br />
linesPerPage = e.MarginBounds.Height/printerFont.GetHeight(e.Graphics);<br />
<br />
while (count < linesPerPage &&<br />
((line = srAppUtility.ReadLine()) != null))<br />
{<br />
yPos = topMargin + (count * printerFont.GetHeight(e.Graphics));<br />
e.Graphics.DrawString(line, printerFont, Brushes.Black, leftMargin, yPos, new StringFormat());<br />
count++;<br />
}<br />
<br />
if (line != null)<br />
e.HasMorePages = true;<br />
else<br />
e.HasMorePages = false;<br />
<br />
}<br />

half-life wrote: yPos = topMargin + (count * printerFont.GetHeight(e.Graphics));

i think problem is in "StringFormat()", you didnt defined some String formats properties
StringFormat PageStringFormat = new StringFormat();
PageStringFormat.Trimming = StringTrimming.Word;
PageStringFormat.FormatFlags = StringFormatFlags.NoWrap | StringFormatFlags.LineLimit | StringFormatFlags.NoClip;
try this StringFormat, i hope it should work

hi
i create a userControl and inheritance it from TextBox control, i was override OnTextChanged event as follow(to change codpage of numbers to arabic):
protected override void OnTextChanged(EventArgs e)<br />
{ <br />
this.Text = this.ToArabicNumber(this.Text); <br />
}
and my method (ToArabicNumber) is here:
private string ToArabicNumber(string text)<br />
{<br />
char[] chars = new char[text.Length];<br />
chars = text.ToCharArray();<br />
StringBuilder sb = new StringBuilder();<br />
foreach (char c in chars)<br />
{<br />
if (char.IsDigit(c))<br />
{<br />
sb.Append(Strings.ChrW(Strings.AscW(c) + 1728).ToString());<br />
}<br />
}<br />
return sb.ToString();<br />
}
my problem is that in runTime, when i enter any value to my custom textBox, it's Text changed and fire OntextChanged event and change codpage to arabic and then fire OntextChanged and so on (Unlimited loop),
how to solve my problem ?
thanks

If the text is already an arabic number, then don't set the text.
protected override void OnTextChanged(EventArgs e)
{
string arabicNumber = ToArabicNumber(Text);
if (Text != arabicNumber)
Text = arabicNumber;
}
|
|
|
|
|
thanks for reply
but my problem is that when i change TextBox.Text in onChangedText, the onChangedText event fire again and so on (Unlimited loop), like this :
TextBox.Text(onChangedText fired) -> ChangeToArabic(onChangedText fired)
-> ChangeToArabic(onChangedText fired) -> ChangeToArabic(onChangedText fired) -> ChangeToArabic(onChangedText fired)-> ...
how to solve this problem ?

Are you suggesting that I gave you a solution that loops infinitely? If you can show where my solution loops infinitely then I'll accept that you still have a problem. If not, then what is your problem?
Please look at my solution. It is very simple. It does loop but once. The reason it only loops once is that I have a condition that stops it looping more than that.
So, my question to you: Did you try my solution before complaining that I don't solve it? Looking at the way you phrased your follow up post, you are basically saying I did not understand your original problem, which implies that you didn't attempt to implement my solution. This suggest that IN FACT you did not understand my solution, rather than me not understand your problem.

thanks Colin Angus Mackay
i tested your suggestion way, but it is not help me, because when i add new character in my textBox(and fire OnTextChanged event) my new text different with old text that i converted to arabic numbers.

Bit it no longer loops infinitely. Right?
hdv212 wrote: because when i add new character in my textBox(and fire OnTextChanged event) my new text different with old text that i converted to arabic numbers.
Then you need to capture the selection before changing the text, then put the selection back afterwards. In a text box a selection can have zero length which representst the position the cursor is at.
