is HD_Copy.exe a Managed C++ mixed-mode assembly? If so, you cant load it from byte[].

If you mean calling the code, you may mark your code blocks as private or internal, otherwise you mean by diassimlying your code you may use Dotfuscator.

to convert you program to DLL :- from the main menu select
Project -> Properties on the properties dialog change the (output type)combobox to (Class Library) then press ok().

Hello all,
in my WinForms application there are many forms. I want to apply one Icon file for all forms and for EXE also
How to do this
any suggetions are appriciated
regards
GV Ramana

For forms :
You can make a base class (say class BaseForm:Form)
Set the icon for this class
And inherit all forms in the project from it..This can also help you applying default styles to all your forms.
|
|
|
|
|
And for the exe itself, set its property from the project properties menu.

UPDATE: This works correctly when I run the BIN directory executable, but not when I run from the debugger.
I have a table adapter with insert method, for testing I use the following in a button click event:
this.classPhotoNamesTableAdapter.Insert(100, 100, 200, 300, 400, "PICNAME");
this.USNTPSDataSet.ClassPhotoNames.AcceptChanges();
If I click the button twice I get a primary key violation, so its valid, but the row is not inserted into the actual db file. Am I missing something?
I also tried this way with the same results:
SqlConnection dataconnection = new SqlConnection();
dataconnection.ConnectionString = global::....USNTPSConnectionString;
dataconnection.Open();
SqlCommand datacommand = new SqlCommand();
datacommand.Connection = dataconnection;
datacommand.CommandText = "INSERT INTO ClassPhotoNames (class_no, x_lower, y_lower, x_upper, y_upper, pic_name) values (100, 200, 300, 400, 500, 'NAMEFIELD')";
datacommand.ExecuteNonQuery();
dataconnection.Close();
datacommand.Dispose();
dataconnection.Dispose();

In my application I have two forms (Form1 & Form2).Form1 having button1(btn1).
When click btn1, I show Form2 by creating by instance of Form2.
Form1 still visible now. If Once again I click btn1, I want to prevent the creation of new instance of form2.It should show already opened Form2.
How can i made this?
I am beginner in c#.Please tell me briefly.

There's no need to post a second thread. The first one you posted is good enough. You just didn't ask your question correctly.
<br />
class Form1 : Form<br />
{<br />
private Form2 myOtherForm = null;<br />
<br />
protected void btn1_OnClick(...)<br />
{<br />
if (this.myOtherForm == null)<br />
this.myOtherForm = new Form2();<br />
this.myOtherForm.Show();<br />
}<br />
<br />
}<br />
That should take care of it.
You could do much more complicated things involving singletons and such, but that's probably overkill.

Hello. I want to learn that converting an excel chart or table to pdf with iTextSharp.dll is possible or not?
If it is possible which classes I must use?
Is there any example or link that you can recommend?
If anybody help me I will be glad.
Thank you.
Murat

It is possible but you have to do a lot on your own.. iTextSharp can write tables by using PdfPTable. However there is no class included that reads an excel file and writes a pdf so you also have to use interop or an excel reader class to get the data from excel.... It's not difficult but it takes while I guess!

In my windows application (C#).
I have a mainform with toolbar control and two additional forms(says subform1,subform2)
when i click toolbarbutton1 subform1 was open.
when i click toolbarbutton2 subform2 was open.
now i have one button in subform2 which is used to rediect the user to the subform1. My requirement is ...,
Instead of create new instance of subform1,i want to use already opened subform1.
give some idea that satisfy my above requirement.

What does that have to do with threading?
Change the constructor of the subform2 to accept a reference to a form. When you create subform2 you pass along a reference either to the main form or subform1. Subform2 can then use that reference to set focus on subform1 either by accessing a method in the main form that does it or do it itself.
A refence to the main form would be the choise if subform1 doesn't have to be created before subform2 is.

b { font-weight: normal; }

But i dont know how make the refrence to another form.
please tell me briefly.

To show any form, you do something like:
<br />
MyForm myForm = new MyForm();<br />
The variable myForm is a reference. If you only have one of those, there will only be one form.
|
|
|
|
|
You probably have used it without knowing it...
The reference of the current form is easy to get. Just use the this keyword.
When you create a form you get a reference to that form:
Form f = new MyOtherForm();
When you create a form where you have modified the constructor to accept a reference, you just pass the reference when you create it:
Form g = new MySpecialForm(this);
or
Form g = new MySpecialForm(f);
---
b { font-weight: normal; }

Hi!
I have an applicatin that needs 2 forms. The first one is the login form and the next one is the main application form. What I need is to pass the login info from the first form to the main form. I've done that by creating for the main form a new constructor that gets 2 parameter, but I don't think it's a good ideea because when i'm creating an object of the main form from the login form if I close the login form the main form it's closing too. I've tried to hide the first form after initiating the main form, but then when I close the main form I can't (or I don't know how to) close the login form.
I would realy apreciate some sugestions. I'm a beginner in C#.
Thanks!

Open the login form as a modal dialog from the main form.
---
b { font-weight: normal; }
|
|
|
|
|
|
Create the form object and use the ShowDialog method to show it.
---
b { font-weight: normal; }
|
|
|
|

<br />
private void main_Load(object sender, System.EventArgs e)<br />
{<br />
LogingForm temp =new LogingForm(); <br />
temp .ShowDialog();<br />
if(temp .CheckLogin() == true)<br />
{<br />
}<br />
else<br />
{<br />
}<br />
}<br />
