Hi All,
I am using Report Sharp-Shooter of PerpetuumSoft for reporting in my project.
I want to insert graph/chart in my reports.
Can anybody tell me or provide some link to me on how to add graph/charts in Report Sharp-Shooter.
I have searched on google but i am mostly getting the links of purchase or free download of software.
Thanks,
Nagendra.

Your best bet is to contact the vendor, they are more likely to know

I'm trying to get the module handle of the loaded dll in order to pass it to SetWindowsHookEx() function. [Bascially I'm using the windows hook approach to inject the dll in another process]. However, GetModuleHandle always returns 0. What could be the issue? Here is the code:
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
public static extern IntPtr GetModuleHandle(string lpModuleName);
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr SetWindowsHookEx(HookType hookType, HookProc lpfn, IntPtr hMod, uint dwThreadId);
IntPtr moduleHandle = GetModuleHandle("HookInjectDll");
// I tried giving full dll path, the .dll file extension, but nothing works. ModuleHandle returned is always zero. I also verified Assembly.GetExecutingAssembly() that the current dll path is correct.
int lastError = Marshal.GetLastWin32Error(); // This returns 0 i.e. success.
hookPtr = SetWindowsHookEx(HookType.WH_CALLWNDPROC, (HookProc)MyHookProc,
moduleHandle,
GetWindowThreadProcessId(targetProcessHandle, IntPtr.Zero));
Any help on this issue?
Thanks

Nope. Your GetModuleHandle prototype is missing SetLastError = true

Marshal.GetHINSTANCE(typeof(MyClass).Module)

You can do this using the designer in your crystal report file.

and to get table names:

For a little something I'm just playing around with today I need the ability for an instance to query the state of one or more other instances.
The various instances will therefore be chained together by some technique.
The important thing about this is that the state of the referenced (source) instance can change and the referencing (client) instance should always receive the current state.
A.Input = B.Output
B.Input = C.Output
A should always know the current state of C.Output
Passing the state by value won't work. I thought about using events, but I don't think they're appropriate for the task.
In C (or C++) I might pass the address (or a reference) to the state value, but that's not easily done in C# and I want it to be read-only to the client.
What I've come up with as a workable technique is delegates, which makes sense, I really want callback functions.
In the above example, C provides a delegate to a method that B passes along to A and A can call to get the state of C.
This works fine, and I'm just wondering whether or not anyone else has done anything like this and how they accomplished it.

I haven't needed this yet.
I see two ways that cascade:
1. polling
C offers a property that B can get; based on that B offers a property that A can get.
2. event driven
as A uses B and should be unaware of C, there must be a mechanism between A and B, probably an event; and similar a mechanism between B and C. So when C changes state, it tells its subscribers (B); and B getting such change, tells its subscribers (A).
And two ways that smash the cascade:
3. polling
define an interface, IMyProperty, and have both B and C implement it; now have B pass C to A as an IMyProperty. A doesn't care whether it is asking B or C then.
4. event driven
you could have B pass on the B->A delegate so it effectively becomes a C->A delegate however that complicates things a bit: B would need an AddEventHandler and RemoveEventHandler kind of methods, and keep the event itself private.

1. I'm doing that, the properties provide the delegate.
2. I have since realized that I probably need multi-cast ability so events may be needed.
3. That won't do it.
4. Except I think I need it to work in the other direction and I'm about to try it that way.
Edit: It works this way too. An output is a property that publishes a delegate and an input is an event (multicast delegate).
Outputs can be wired to inputs as required.
The receiving object only needs to execute the delegate(s) to determine the input value without caring where the value came from.

Arrg! It works until I create a loop, in which case I get infinite recursion and a stack overflow. 
Ah, well, I think I can work around that.

Was happily coding away, and I did this:
if (blahblahblah)
{
.....
lock(blahblahblah)
{
.....
}
.....
}
I then realized I had gotten the scopes backwards, and corrected it. Is there any kind of switchscopeify feature somewhere in vs2008 to do that superquick?

right my aims are to create a kind of wizard , i dont know how to use the wizard class so i thought of some quick code for it and it didnt work *sigh* anyway so i have a tabcontrol on the gui (DotNetbar) and then once i open the first user control and on the first one call back to form1 with a public void for example :
public void SetPage(int PageNum)
{
if (PageNum == 1)
{
Page1 page1 = new Page1();
page1.Dock = DockStyle.Fill;
page1.AutoSize = true;
TabItem item = this.tabControl1.CreateTab("");
item.AttachedControl.Controls.Add(page1);
this.tabControl1.SelectedTab = item;
Application.DoEvents();
}
if (PageNum == 2)
{
Page2 page2 = new Page2();
page2.Dock = DockStyle.Fill;
page2.AutoSize = true;
TabItem item = this.tabControl1.CreateTab("");
item.AttachedControl.Controls.Add(page2);
this.tabControl1.SelectedTab = item;
Application.DoEvents();
}
if (PageNum == 3)
{
Page3 page3 = new Page3();
page3.Dock = DockStyle.Fill;
page3.AutoSize = true;
TabItem item = this.tabControl1.CreateTab("");
item.AttachedControl.Controls.Add(page3);
this.tabControl1.SelectedTab = item;
Application.DoEvents();
}
if (PageNum == 4)
{
ErrorPage error = new ErrorPage();
error.Dock = DockStyle.Fill;
error.AutoSize = true;
TabItem item = this.tabControl1.CreateTab("");
item.AttachedControl.Controls.Add(error);
this.tabControl1.SelectedTab = item;
Application.DoEvents();
}
if (PageNum == 5)
{
FinishPage finish = new FinishPage();
finish.Dock = DockStyle.Fill;
finish.AutoSize = true;
TabItem item = this.tabControl1.CreateTab("");
item.AttachedControl.Controls.Add(finish);
this.tabControl1.SelectedTab = item;
Application.DoEvents();
}
}
so the command on the form would be SetPage(1); for page 1 but for another on user control i would have it :
Form1 form = new Form1();
form.SetPage(3);
Application.DoEvents();
But it seems to not be loading, any help ? or anyone can point me to using the wizard as google for me doesent pull any help on it or unless i am searching it wrong , searching : c# code using wizard class ,
Anyway thanks for your time guys !

hi
where i can learn the basic of class - as simple as i can (C#)
class,get,set,OOP
thank's
|
|

|

Here is a recipe:
1. Read this[^];
2. Go to the bookstore, and choose, buy and study an introductory book on C#;
3. Read some articles here at CodeProject;
4. Experiment, and keep reading;
5. Ask intelligent questions at CP.

I have written a User Control and made it dll from a classLibrary Project.
This User Control get the Name of the Form (in Project that we use this dll) in textbox1 and then do something with the controls on this form. Now my question is how i can Cast textbox1.Text (of this user control) to Form ?
see i use this user control in FormA and when the project runs it gets any form name execpt itself(the form that has this user control) in textbox1 (this textbox1 is also in the user control)and then the user control brings out all control on that form and show all properties of that control.
I have used this code in User Control:
Type type = Type.GetType(txtFormName.Text, false, true);
Form frm = Activator.CreateInstance(type) as Form;
I get this error :
Value cannot be null.
Parameter name: type.
Alert :
This user control has been made in another project and i have build DLL and now I use this DLL in my another projects.

This has returned null:
Type.GetType(txtFormName.Text, false, true);
I think txtFormName.Text contains something bad, not a type name.
Maybe the type is contained in an assembly that is not loaded?

|

No
it contains windowsapplication4.Form1
|
|
|
|
|
It what assembly this type is contained?
windowsapplication4.Form1

Hi,
I am certain this question must have been asked many times before, but I am struggling to find a plain and simple answer to the following: can you get a wrapper (preferably 'thin') for OpenGL that can be used when developing C# code in Visual Studio to run on a PC?
I am sure I once read about something called 'SharpGL' but I don't seem to be able to find anything about it now. (Admittedly, I've only spent 30 minutes or so on this up to now, but I thought someone here might be able to point me in the right direction.)
Any pointers would be very much appreciated.
Best wishes, Patrick
