I solved the complete Problem, but without IReferenceService.GetComponent()...
... would still be interresting if anyone knows about this...
My solution:
Get the RootComponent with IDesignerHost
Check if the Component you want to use is a Field of the RootComponent by using Reflection:
FieldInfo FI = RootComponent.GetType().GetField(ComponentName, BindingAttributes...);
-> as Reflection on the RootComponent itself is not possible, you will only get Results for Fields of a BaseType
-> you can get also private fields of the BaseType (The code needs ReflectionPermission!)
-> you can be (almost) sure, that all Components for which you cannot find fields, are Components with fields in the RootComponent.
-> all Components with fields in the RootComponent are accessible
-> all private fields you got by reflection are not accessible
best regards,
Bernd

Hi,
How to make a button transparent?
|
|
|
|
|
Set the Opacity property to something less than 100%
|
|
|
|
|
Button does not ve a opacity property as far of my knowledge
|
|
|
|
|
Button control provides the opacity function ???????????????????
|
|
|
|
|
Hi,

Hi,
I have tested it here, and its working fine.
See I have done the Following to test :
I have created Form as "Form1" and a button as "button1" over it.
Form1.BackgroundImage = TransparentButton.Resource1.Image2;
This just to check if transparentcy is working.
For the Button too I have used a Bitmap.
button1.Image = TransparentButton.Resource1.Image1;
Now in the Constructor of the Form I have set:
button1.BackColor = Color.Transparent;
Also, please set the
FlatStyle as "Popup" for the "button1".
That makes the button transparent, meaning u can see the Image2 from over the
button body.

hi,
Thanks. I don't need any images both on button and form. My idea is to place the button dynamically on the datagrid and when dragged it should be transparent. Hope u got my point
Bye

hi,
if you are using .net v1.1 then you have to set the backcolor of the button to Color.Transparent.
like:
this.button1.BackColor = System.Drawing.Color.Transparent;
and FlatStyle should NOT be "System.Windows.Forms.FlatStyle.System"
It can be either Flat, Popup, or Standard; but NOT System

{
class WordPair
{
string[] rightpair = new string[] {"below\tunter", "blue\tgel", "cat\tgelb", "cat\tdie Katze",
"red\trot","the dog\tder Hund","to read\tlesen"};
string [] wrongpair = new string []{"below\trot", "bue\tlesen", "cat\tunter", "red\tgelb",
"the dog\tdie katze"};
}
}
I am a beginner in C# programming and seeking advice.
What I am trying to do here is to build up an application in 4 parts.
Part A.
Which I have already started with the code above, to be an application that has the class WordPair implemented. The application creates a word pair object and calls the method for matching with two different strings-one that produces a match and one that doesn't & to show the results of these matches.
Part B.
An application in the same programme but as part B, that reads in the 'word_list.text' ( that is located in the solution folder). This part to be able to check each line.If the line has a word pair(i.e. two strings separated by a '\t') it puts this string into an ArrayList. If the line does NOT have a word pair, the application put that line into a file 'wrong_lines.txt'(that will be located in the solution folder).This application to count the number of lines without word pairs and reports this number to the user & shows all the input lines in a rich text box. If the word list file is not available, the program to produce an error an appropriate message.
Part C
Trying to have this part of the programme to be an application that reads the wordlist, puts the word pairs into an ArrayList of word pair objects, writes the wrong_lines files, reports on faulty pairs, allows the user to ask for a word and attempt the answer, also tells if the user's answer is correct.
Part D.
This to be a combination of Part A, Part B and Part C.
AM NOT SURE IF AM ON THE RIGHT TRACK WITH THE PART OF MY CODE ABOVE.SEEKING ADVICE ON WHAT COULD BE A BETTER WAY OF WRITING THE RELEVANT CODES.

This sounds very much like homework to me...
Anyway, I think you should include a property "Word1" and "Word2" (or something more meaningful - can't tell you from your description) in your WordPair class.
To have more than one WordPair you could use List<WordPair>.
Btw., your rightpair array (which you don't need in WordPair IMO) contains several errors: Should be "blue\tblau" and "yellow\tgelb".
Oh, and please stop shouting.

mav

Hi All,
I am having a ASPX page on whose submission I open a PopUp Window for
sending mails.In the main page I have four hidden variables for
setting the MailTo Mailcc,MailSubject and MailBody fields which I am
getting in my PopUp Window by using
if((document.getElementById("hdnForPOst").value)=="1")
{
document.getElementById("txtTo").value=window.opener.document.getElementById("hdnMailTo").value;
document.getElementById("txtCC").value=window.opener.document.getElementById("hdnMailCC").value;
document.getElementById("txtMailSubject").value=window.opener.document.getElementById("hdnMailSubject").value;
document.getElementById("txtMailBody").value=window.opener.document.getElementById("hdnMailBody").value;
}
hdnForPOst is the variable set for sending mail.
This script I have pasted in a after my controls code.
The problem is that sometimes this code does't execute and I get a
blank popup Window.
I have checked by putting alerts inside script block also.These alerts
also dont execute.It happens only at times and no specific scenario.
Anybody can help please?

Hey Please put this Javascript in a Seperate js file and call this srcipt in your aspx page through src="_ur.js"file and work like that.
First attached it to a default.htm page and see if the scripts works fine then attach the script to your .aspx page.

Strange one for the experts.... I am using windows 2003, visual studio 2005
I can create and use a single instance performance counter without issue...sort of - will explain later.
I am not able to get a multiple instance performance counter to work. Ther performance counter is added but <no instances=""> are shown so I am not able ot select the performance counter to monitor. The code below that adds an instance runs without throwing an error.
The code:
if (!PerformanceCounterCategory.Exists("JUNK"))
{
CounterCreationData ccd = new CounterCreationData("numberOf", "numbers", PerformanceCounterType.NumberOfItems32);
CounterCreationDataCollection ccdc = new CounterCreationDataCollection(new CounterCreationData[] { ccd });
PerformanceCounterCategory cat = PerformanceCounterCategory.Create("JUNK", "junk category", PerformanceCounterCategoryType.MultiInstance, ccdc);
using (PerformanceCounter c = new PerformanceCounter("JUNK", "numberOf", "instance1", false))
{
c.RawValue = 10;
}
}
using (PerformanceCounter c1 = new PerformanceCounter("JUNK", "numberOf", "instance1", false))
{
for (int i = 0; i < 10; i++)
c1.Increment();
}
A single instance performance counter works but not as expected (the above code, but category marked as single instance and the instance not being specified when creating the counter). The counter is added and I can view in perfmon, but it is not until I have the counter added to perfmon that the incrementing is persisted.
Any ideas?

Hi all,
Ive been working on a program that does a few easy equations but i am running into problems when i run into larger numbers where the numbers start to crash out. in the source below can you think of aything that i could change to stop this from happening.
secondly some times i have to display some larger numbers but when i convert to string i get it in scientific notation 234230000e^12 type stuff
is there anyway to just display it straight numbers??
below is my source code
Random random = new Random();
float X1, X2, X3, Y1, Y2, Y3;
//STEP3 MAKE RANDOM PNT1
X1 = random.Next(2,10000);
Y1 = random.Next(2,10000);
//STEP2 MAKE PNT2 WITH CONSTANT ( FROM TEXT BOX)
X2 = Convert.ToInt64(textBox7.Text);
Y2 = 0;
X3 = 1;
Y3 = 1;
//STEP4 GET SLOPE FROM PNT1 AND PNT2
float slope = (Y2 - Y1) / (X2 - X1);
float t = random.Next(2,10000);
//STEP5 GET RANDOM POINT ALONG LINE MADE PNT1 AND PNT2
X3 = t + X2;
Y3 = t * slope + Y2;
//OUTPUT TO TEXTBOX
textBox5.Text = t.ToString();
textBox6.Text = slope.ToString();
textBox1.Text = X1.ToString();
textBox2.Text = Y1.ToString();
textBox9.Text = X3.ToString();
textBox8.Text = Y3.ToString();

numbers have a finite range, if you go over, it breaks.
YEs, string.Format can be used to format number strings.

Hey go with the data type of Decimal (or)Numeric instead of Float.
Because for Scientific Notation I usually go with Decimal.
Regards,
Satips.

For your first issue, change the float (7 digits) to double (15-16 digits). Next for your formatting issue, you can insert with the .ToString("formatting string")
