Lets see if you guys can figure this one out.
I have WriteProcessMemory 'ed a path name of a .DLL into a remote process after VAlloc 'ing it.
<b>
Simple so far. Just a pathname in a remote process.</b>
Now I want to create a remote thread in that process using CreateRemoteThread, however, and this is the tricky part, I want to pass the address of LoadLibrary as CreateRemoteThread's starting address. Now I know I could just plug in the real address of my LoadLibrary, however I know this address changes from not only OS to OS version but from DLL version to DLL version. This is so that once the thread is created is starts directly at LoadLibrary, loading the path'ed DLL, and exits the thread when LoadLibrary is finished.
CreateRemoteThread(hProcess, 0, 0, <Address of LoadLibrary>, szRemotePath, 0, &dwTID);
Is there anyway to do this?
I know in C++ I would simply just use &LoadLibrary, however this does not work in C#. Even after PInvocation of LoadLibrary it will not do so. AddressOf doesn't work either.
Thank you in advance, and you'll get another after your answer!

Total guess: you could call LoadLibrary on kernel32.dll to get kernel32's HMODULE, then call GetProcAddress to get the address of LoadLibrary. Then you can pass that address to CreateRemoteThread.
Stability. What an interesting concept. -- Chris Maunder

Agreed. Actually I found a sample in a blog exactly doing this.
private void foo(IntPtr handle)
{
SecurityAttributes a = new SecurityAttributes();
hThread= CreateRemoteThread (handle, ref a , 0,
GetProcAddress(GetModuleHandle("KERNEL32.DLL"),"ExitProcess") ,
54,0,ref threadid);
//blah blah
}
[DllImport("kernel32.dll")]
static extern IntPtr CreateRemoteThread(
IntPtr hProcess,
ref SecurityAttributes lpThreadAttributes,
int dwStackSize,
IntPtr lpStartAddress,
uint lpParameter,
int dwCreationFlags,
ref int lpThreadId
);
struct SecurityAttributes
{
int nLength;
uint lpSecurityDescriptor;
bool bInheritHandle;
}
[DllImport("kernel32.dll")]
static extern IntPtr GetProcAddress (IntPtr hModule, string lpProcName);
[DllImport("kernel32.dll")]
static extern IntPtr GetModuleHandle (string lpModuleName);

Folks this is a simple amost silly question, but still i would like to ask:
I would like to imitate form close event identical to when you presses X to close, when I click on a button for close a form. I basically want to catch all exception in from control when the button clicked.
Sincerely,
Max Pastchenko

Can you try explaining it again?

well, i thought this was rather a simple question.... hmmm
Well here is what I tried, on the button click event, I tried calling form closing event where say textbox validation occured, but when exception is thrown, It does not get that piece of code.
Sincerely,
Max Pastchenko

Here we go again,
Lets say i use this.close for close a form as this point ( when i press on a command that closes my form). I want to know an alternative way of doing so. This is because form closing event is not being called. It does get called when I press X of the form.
What i want to acoomplish is trap any control value errors on form close (is text field empty or not when form closes). Does this help?
Sincerely,
Max Pastchenko

Better validation check to simply validate values on text cahnged event

Hi,
I have a procedure in Form_A which changes the form text and the label caption on the same form and display a message. The procedure is:
public void yahaa()
{
this.Text = "TEST";
lblName.Text = "TEST";
MessageBox.Show("Yahaa!!", "STOP!!", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
I am calling this procedure from Form_B
but I am just getting the message displayed without changing the form text and label caption
first, I want to ask wehther what i'm doing is correct because I want to add some database action in the same proceure.
then, if it is correct.. why the form text and label caption are not changed..
Many Thanks

The pedant in me wishes to remind you that this is a "method" not a procedure.

Are you sure? The label and form text should change on Form_A. Are you expecting it to change on Form_B?

thanks for the reminder
no.. i am not expecting it to change Form_B but it's not even changing Form_A. I am only getting the messagebox without the form text and label caption & i don't know why!!

How are you exposing the method to Form B and how are you calling it?
Code snippets help alot!

Hi,
I have already posted the method code in my message but if you mean how do i call it from Form_B then the code is:
frmB Form_B = new frmB();
Form_B.yahaa();

This code has nothing to do with calling anything on Form A. How abo starting over and showing us the code, copy-and-paste.

Form_A:
private void mnuNew_Click(object sender, System.EventArgs e)
{
NewEziForm.ShowDialog();
}
Form_B:
frmEziLife EziLifeForm = new frmEziLife();
EziLifeForm.new_record_id = proposalTable.GetInt32("EZI_ID");
EziLifeForm.yahaa();
Just the relevant parts would have been sufficient. Your Form_A creates an instance of Form_B, then shows it using Form_B.ShowDialog(). NOWHERE in your code do you pass the current instance of Form_A to Form_B. This means that Form_B has no way of calling the code on your first (and only) instance of Form_A.
In Form_B, you're creating a NEW instance of Form_A and never showing it. This is the instance that you're calling this Yahaa method on. This is why you can see the changes to the title bar text of the Form_A that you can see.
You have to create a public field on Form_B that takes a Form object. Set that field to Form_A before you call ShowDialog on Form_B. When you call back to the Yahaa method, you have to do it using the instance of the form in your public Form field.

Hi,
thanks for your reply..
but wait..
that looks little complicated..
can you explain it step-by-step with sample
with many thanks.....

You really shouldn't be making call's mback to the parent form anyway. This is not proper practice and leads to spaghetti code.
But, here it is:
Form_A
public class frmEziLife : System.Windows.Forms.Form
{
frmEziLife_New NewEziForm = new frmEziLife_New();
.
.
.
public void yahaa()
{
this.Text = "TEST";
this.lblName.Text = "TEST";
lblName.Refresh();
MessageBox.Show("Yahaa!!", "STOP!!", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
this.lblName.Text = "TEST";
}
private void mnuNew_Click(object sender, System.EventArgs e)
{
NewEziForm.myParentForm = this;
NewEziForm.ShowDialog();
}
.
.
.
}
Form_B
public class frmEziLife_New : System.Windows.Forms.Form
{
VistaDBDatabase eziDatabase = new VistaDBDatabase();
VistaDBTable proposalTable = new VistaDBTable();
Form myParentForm;
.
.
.
EziLifeForm.new_record_id = proposalTable.GetInt32("EZI_ID");
myParentForm.yahaa();
this.Close();
.
.
.
}

i tried it but getting:

|

Whoops. Form_B should have been this:
public class frmEziLife_New : System.Windows.Forms.Form
{
VistaDBDatabase eziDatabase = new VistaDBDatabase();
VistaDBTable proposalTable = new VistaDBTable();
frmEziLife myParentForm;
}

thank you thank you thank you very much
problem was solved...

Are you asking how to call the yahaa method (while it resides in the .DLL) from the forms?
Easy. Create a seperate class and more you're yahaa code to it. Since yahaa deals with the form properties, you'll have create the method with the ability to take a Form object as a parameter.

Is there a way to vertically scroll (at least specify the first visible node) a TreeView without scrollbars being shown (that is the Scrollable property being off). Initially I thought that the Scrollable property indicated whether the scrollbars are shown or not but it seems to mean more than that as it causes Node.EnsureVisible() to not work as well.
I need to use the TreeView side by side with another control and I would prefer for the other control to deal with scrolling and not have a TreeView scrollbar in the middle between them.

|

Not without drawing the entire treeview yourself, search for "custom treeview" for some articles.
You're right, no scroll bars equals no scrolling.

This is probably a newbie question, but I could use some help making sure I get it right. Over the past couple of months I've taught myself a boatload of C# as well as some VBA and some ADO. I've developed a database application on my own computer at work accessing a database that I set up in Access (as a project) and that I access through an instance of MSDE 2000 running on my machine.
Here is how I connect to the server from my own desktop (I've changed a few of the details of DataSource and workstation ID because I'm not sure if that's the kind of thing you post in the open or not):
@"Integrated Security=SSPI;Packet Size=4096;DataSource=""EC-BJACOBS"";Initial Catalog=BenefitSelectDBSQL;Provider=""SQLOLEDB"";Workstaton ID=""EC-BJACOBS"";Use Encryption for Date=False"
So that's been working fine for me as I develop this sucker over the last couple of months, but now I'm nearly done and I want to be able to run the program remotely (I'm sacrificing my desktop on the altar of experimentation and letting it be a server for a while). Before anyone laughs that my company is trusting someone with a degree in math and no coding experience (other than a minor in CS) to build and deploy a distributed database application, it's not mission critical (at all) and they don't have anyone else better.
So here's my question: what modifications do I need to make so that other people (already on the network) will be able to access the database from their own computers? Do I need to make any changes to the string above? Or is it good to go?
If it's a long answer, just point me in the right direction and I'll do the research.
Thanks for the help!
