Hello,
I have a parent form where i load a child form on a panel. Now i want to access from the panel a control on the parent, here the toolstripprogressbarr. How can I manage that?
On the parent form I do the following to load the child in the control panel1 of parent.
newF = new Child01();
newF.TopLevel = false;
newF.Parent = panel1;
newF.Show();
Now I do a small manual operation in the Child01 form which leeds to an operation. during this operation I'd like to make the toolstripProgressBar Visible.
I hope that someone can point me in a good direction.

Have the child throw an event and the parent will catch it and and then do stuff. Create a delegate in the child, have the delegate point to a parent method, when the event runs, the child will call its delegate, which of course will call the parent method.
There are examples of this on MSDN, just search for delegate, event, or maybe subscriber/publisher design.

Hi,
I'm trying to display a string that has some weird characters in hex so I can see what they are. I've tried the code below but I'm still getting the characters, not the hex values that make up the characters:
<br />
string sHex = string.Format("{0:4x}", sPassword);<br />
How do I display a hexidecimal representation of the string?
Thank you,
Glenn

Loop through the characters of the string, convert each character value to an int and format that as a hex value.

I'm writing a deployment package and I am down the the last piece of what I need to do. All of the DLL's will have been installed. Now I need to call my custom installer and perform the following two items:
Register 5 DLL's in the GAC
Add registry keys to those components so they show up in Add Reference
Are there any managed API calls I can make to accomplish these two tasks? Or do I have to use out of process calls to GACUTIL and make Win32 calls for the registery?
Oh yes, I'm using Visual Studio 2003.
Thanks!

Well I think I have the solution to my problem.
First for the registry entries I can just use the Registry portion of my setup project to dynamically manage those entries.
For GAC registration, I'm creating a .cmd file with the gacutil commands then I create a process for that .cmd file which I then do a process.Start(); followed by a process.WaitForExit(); and I think I've got it.

Hi Everybody !
My name is Kostas and i build a C# Application about e-learning .
My problem is to make the *.mpg files come with my Application not to play on any Media Player exept my application .
I can Encode and Decode my files with many tools i found to protect them .
But the Decoding must be on the fly - So the user dont have to wait to Decode the media and then Play .
Please is there anyone can help .

Hi Kostas
From my point of view i think this idea isn't practical at all BUT
you can Compress them in a password protected pckage ( like zip, rar, and preferably 7z ) and silently decompress it in the background and then play it

I create a form in the first Part of my class via
FormBuzWindow myFormBuzWindow = new FormBuzWindow(); and set this one visible.
Via pressing ALT+F4 this one can be closed. Is there a way to "reuse" the myFormBuzWindow Variable. I tried a to use myFormBuzWindow = new FormBuzWindow(); in case I notice this is gone, but the form never shows up again. Did I do something wrong or knows anyone how to make the form come back again?

That's a really dangerous security problem. You should use parameterized queries, like this article says:
SQL Injection Attacks and Some Tips on How to Prevent Them[^]
And posting code is not enough, you have to ask a question. Also, don't post much code, just a few lines where you are having your problem.

hi everyone!
i think the code was right but it's always reported that there is an error at:
objReader = cmd.ExecuteReader();
i have no idea why was that

yamacom wrote: SQLcmd = string.Format("select UserName,PassWord from tblAccount where UserName = {0} and PassWord = {1}",strUser,strPass);
You have to enclose the user name and password in quotes. Eg:
SQLcmd = string.Format("select UserName,PassWord from tblAccount where UserName = <big><big>'</big></big>{0}<big><big>'</big></big> and PassWord = <big><big>'</big></big>{1}<big><big>'</big></big>",strUser,strPass);BUT that is not a secure practice. You should use parameterized queries, and store the hash of the password instead of the actual password in your database. Read the article I linked to in my previous post. Better yet, I'll link to it again:
SQL Injection Attacks and Some Tips on How to Prevent Them[^]
[EDIT: next time, post just a little code, the problem you're having and your question, and any error message you might be getting. That will give your question more chances of being answered.]

Hi Guys,
I'm creating a descent dll to use for future programming with COM objects.
I'm having trouble with passing some parameters like the following:
<br />
unsafe public long GetDlgText(long dlgid, long fldid, long row, long col, [MarshalAs(UnmanagedType.BStr)] string text){<br />
long returnvalue = -1;<br />
try{<br />
object[] cmds = { dlgid, fldid, row, col, text };<br />
returnvalue = Convert.ToInt64(Interaction.CallByName(idisp, "GetDlgText", CallType.Method, cmds));<br />
}
catch(Exception e) {<br />
lasterrormessage = "Could not invoke GetDlgText function: " + e;<br />
}
return returnvalue;<br />
}
which I've translated from the following:
long GetDlgText(long DlgId, long FldId, long Row, long Col, BSTR* Text);
I'm calling it like this:
string test = "";<br />
idisp.GetDlgText(101, 47, 1, 0, test);<br />
I get a TYPE_DISMATCH error and I'm pretty sure it's the last parameter (all the complete non-pointer methods work)
What do I do wrong? I've searched on Marshal, passing by value and a lots of other things, but MSDN isn't kind to me  .
I hope somebody can help me, tnx!
No hurries, no worries.
