I have a program that checks if file exist and if it does it reads the version as follows:
*********************************************
if(File.Exists("c:\\MyDLL.dll"))
{
FileVersionInfo VER = FileVersionInfo.GetVersionInfo("c:\\MyDLL.dll");
label9.Text = "MyDLL.DLL";
label10.Text = VER.FileVersion;
}
else
{
label1.Text = "MyDLL.DLL";
label12.Text = "File does not exist";
}
****************************************
The code works fine, the problem is that I have to repeeat this for every DLL in that folder.
Is there a better way to read all of the DLLs in a particular folder?
any help will be greatly appreciated

Buy yourself a good book. I used this one[^] and really liked it.
If you think you're going to buy a lot of books, look into O'Reilly Safari[^] or ACM's Professional Development Centre[^]. Both have online books sections for a set monthly fee.
If buying a book is not an option, there's tons of stuff available on the Web:
C# Tutorials[^]
And, don't forget all of the wonderful articles here on CP.

Then search this site for examples. Several articles have been written pertaining to GDI drawing, including the drawing of curves and rounded rectangles, in C#, are found on this site.

Hi all,
I have a custom control, derived from System.Windows.Forms.UserControl. I'm using AutoScroll in this control to provide scrolling. I've overridden OnPaint in my control to do the drawing of the control. When the user scrolls, an Invalidate() is done on the control with the area that is newly exposed so that the invalidated area is as small as possible (this is done by the framework, not by me). Now my problem is that I want to update more of the control than just the part that is scrolled into view. I see two possibilities:
- Update the whole control when the user scrolls. Unfortunately I don't see a way to tell ScrollableControl (the class that UserControl is derived from that provides scrolling capabilities) to update the whole control when scrolling; I also don't see a way to get to the scrollbars directly to connect to a Scrolled() event (as confirmed in the windows.forms Petzold).
- Change the invalidated region from within the OnPaint handler. If I could find a way to tell the control to redraw everything and not just the rectangle that was passed to Invalidate() I could do that at the top of my OnPaint() member and be done. But no matter what I try, it seems I cannot update the invalidated area without calling Invalidate(), which will also send a WM_PAINT - I don't want since I'm already in OnPaint and that will create an infinite loop! The hack I came up with is something like this:
private bool m_DoingSecondOnPaint = false;
protected override void OnPaint(PaintEventArgs pea)
{
if (!m_DoingSecondOnPaint) {
m_DoingSecondOnPaint = true;
Invalidate();
} else {
m_DoingSecondOnPaint = false;
}
... do rest of drawing here ...
}
but as you can see this means that all the drawing code is executed twice for every time I want to draw the control. Is there a better way to do this?
cheers & thanks,
roel

Hello,
I have:
this.styleStages.GridColumnStyles["Name"]
is there a property, that will allow me to center the Column Headers in
my datagrid? If I use Allignment property right after ["Name"], it will just center the values for the column. Any ideas?
Thank you
|
|
|
|
|
Yeah, check out the format section of the property builder in design view. You can set the alignment of the header, item and footer.

I am doing it progmatically, so I don't even see the columns, and headers im the grid. How would you do it by coding it?
Thank you

Hello there
I have created an event in my userControl with the name "MyEvent"
now I have one windows form inside UserControl to display some records if they cannot be displayed on the usercontrol ( something like popup Form)
MyEvent (the created event) fires on the click of record on userControl. I want to run that event on my popup Form as well. but when I created the event in popup form it stays null so it never fires. How Can I trigger the event on the UserControl child form (popup form) to pass the values to UserControl main event "MyEvent" so that they can be further passed to sample demo application form testing this control ?

i wanna make some controls like textbox or buttons visible only on the event of double click on a picturebox
i wrote
if(pictureBox1.click)
{
textBox1.visible=true;
}
but it doesn't work

Learn about events before looking for help here  . It's elementary knowledge in application programming.
Okay - you wrote this:
<br />
if (pictureBox1.Click == true)<br />
{<br />
...<br />
}<br />
This just checks if there is any event handler. You must hook-up new event handler first:
<br />
pictureBox1.DoubleClick += new EventHandler(PictureBoxOnDoubleClick);<br />
Then add this handler and add your code.
<br />
void PictureBoxOnDoubleClick(object o, EventArgs e)<br />
{<br />
textBox1.Visible = true;<br />
}<br />
If you don't know why the parameters are object and EventArgs, learn sth about delegates.

pls try this code , i hope it can help
1-drage a button1 on your form
2-set its visible proprty to false in thje proprties window
3-drage a picturebox1
4-double clic pic box & u,ll find
private void pictureBox1_Click(object sender, System.EventArgs e)
{
}
this is an event defination so replace "click" with "DoubleClick" like this
private void pictureBox1_DoubleClick(object sender, System.EventArgs e)
{
}
5-open the +win form generated desiner generated code
6-open the + private void intialize component
7-search for this
this.pictureBox1.Click += new System.EventHandler(this.pictureBox1_Click);
8-replace with
this.pictureBox1.DoubleClick += new System.EventHandler(this.pictureBox1_DoubleClick_1);
9-private void pictureBox1_DoubleClick_1(object sender, System.EventArgs e)
{
button1.Visible=true;
}
where button1 is the button1

I am fairly new to C# and am trying to export the text from a multi-line textbox to an external file. I am familiar with SaveFileDialog when exporting the contents of a DataGrid, but am unsure as to how I would assign the textbox data.
Here is what I would have done if I were exporting the data from a C1TrueDBGrid. I am sure that I am just missing something simple 
-------------------------------------------------------
protected virtual void Export()
{
System.Windows.Forms.SaveFileDialog saveFileDialog = new SaveFileDialog() ;
saveFileDialog.Filter = "Excel |*.csv|Text|*.txt" ;
saveFileDialog.InitialDirectory = @"C:\" ;
saveFileDialog.OverwritePrompt = true ;
saveFileDialog.FileName = "dbview_" + this.tableName.Replace(" ", "");
saveFileDialog.Title = "Database View for " + this.tableName.TrimEnd() ;
saveFileDialog.ShowDialog() ;
try
{
if (System.IO.File.Exists(saveFileDialog.FileName))
{
System.IO.File.Delete(saveFileDialog.FileName) ;
}
this.c1TrueDBGrid1.ExportToDelimitedFile(saveFileDialog.FileName,
C1.Win.C1TrueDBGrid.RowSelectorEnum.AllRows, ",", "", "", true, "ASCII") ;
System.Diagnostics.Process.Start(saveFileDialog.FileName) ;
}
catch {}
}

Here is part of an example from MSDN that shows how to write text to a file:
StreamWriter sr = File.CreateText(FILE_NAME);<br />
sr.WriteLine ("This is my file.");<br />
sr.WriteLine ("I can write ints {0} or floats {1}, and so on.", 1, 4.2);<br />
sr.Close();

b { font-weight: normal; }

I am having trouble to set my drawing shape in center. When I used translatetransform and it went perfect center. But when I used scaletransform, it went bigger and went different locations. I didnt get it at all. I tried to do different methods and I still dont get it. tell me what is going on. Thanks!!
private void Part_PreviewPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
GraphicsPath grfxPath = new GraphicsPath();
//
//added grfx by using graphicspath shape:line,arc,etc///
//
float fMidPointX = nPanelWidth/2;
float fMidPointY = nPanelHeight/2;
e.Graphics.TranslateTransform(fMidPointX,-fMidPointY);
e.Graphics.ScaleTransform(7.0f,7.0f);
e.Graphics.DrawPath(new Pen(Color.Black, .03f),grfxPath);
}

All transformation you do are composite of each other.
If you translate and then scale, then the translate will also be scaled.
To get your desired effect, divide you translate by your scale:
float fMidPointX = nPanelWidth/2;
float fMidPointY = nPanelHeight/2;
e.Graphics.TranslateTransform(fMidPointX/7f,-fMidPointY/7f);
e.Graphics.ScaleTransform(7.0f,7.0f);
e.Graphics.DrawPath(new Pen(Color.Black, .03f),grfxPath);
your pen will also be scaled, so instead of now being 0.03f, it will be 0.21f
