Try passing the HBITMAP handle, so you can get the image in .NET with Image.FromHBitmap, or pass the string containing the image path on the hard disk, so you can get the image in .NET with Image.FromFile.

It's hard to tell... your questions are way too vague... Here you are some links to the documentation.

Image.FromHbitmap[^]
Image.FromFile[^]
LoadImage function[^]
Windows Data Types[^] (look for HBITMAP into this page).

Be more specific. I have no ideea what exactly you want.

Pass a filename to the app args[] so that it(the app) opens the image automatically? Like in double clik from desktop?

Or form another app? or From/To a DB?

All the best,

Dan

I have:
1.. MFC application (application of test)
2.. C# dll ( ActiveX control : COM)

I have implimented method in the Dll that receive Object (which I think it works) with name AddContextMenu(string A_strCaption, Object A_Icon);

So what I need is to Load a picture from Hard Disc and pass it as parameter for this method.

this is some code c++ where I have to call and pass the picture :

MyCtrlActiveX->AddContextMenu(_T("Assign PN"), ?????);

What kind of application? Console app? If so, just pass the filename as a command-line parameter and handle it in the code.

The first thing to do is to find the documentation for this function and see if you can determine what a status of -1 indicates. If it follows the usual patterns then there should be some more data somewhere that will give you a more specific reason.

I must get a clever new signature for 2011.

This error captured at the time of establishing connection to the database.

Assuming both are running on the same machine, it sounds like a possible permissions issue. Does the account the Scheduler task is using have permissions set in the Oracle client config?

It's probably a permissions issue as your windows service will be running under its own identity as opposed to your user identity. To resolve this, take a look at these threads 1[^] and 2[^].

master form in .net winform 1.1

How to create master form in .net winform 1.1 same as in asp.net master page

Thanks in advance

WinForms works in a different way than ASP.NET, there is no masterpage-concept. You can create a new form, and inherit from it. Would look something like this;

public MyMasterForm: Form
{
  // stuff
}

public MyNewForm: MyMasterForm
{
  // more stuff
}

Good luck

You can do as Eddy suggested, or otherwise you could create one form with a panel that gets populated with Usercontrols.

C# and local SQL server connection [Solved]

JoplinsSlave21-Mar-11 23:20

Hola,

So here's the thing..

I'm using Visual Web Developer 2010 Express and SQL Server 2008, and I'm trying to connect to this goddamn database using C#.

I've created an ASP.NET Empty Website, and I've created an SQL Server Database in the project as well.

So here's how my Page_Load function looks (where I try to connect to the database):

protected void Page_Load(object sender, EventArgs e)
{
    SqlConnection sqlCon = new SqlConnection("server=localhost;database=Database;Trusted_Connection=yes;connection timeout=8");

    try
    {
        sqlCon.Open();
    }
    catch (Exception err)
    {
        errorLbl.Text = err.ToString();
    }
}

But it just won't work...
I'm obviously doing something wrong here, but what?
And what's this bullshit about username and password in the connection string? It's just a local database for god's f***ing sake!!!!

Thanks in advance,

Jop

You missed the vital piece of information out of your rant here - what's the exception? Throw us a bone here.

It's a local database that can be evaluated by outside systems, so I'd assume that security might be reasonably important to you.

At a guess, I'd suspect that the issue you are facing relates to the fact that the user identity you think is hitting the database is not the one that is actually hitting the database. When you develop a website and host it in your webserver, by default it runs under a user account with lowered privileges (for security reasons). This means that even though you are connecting from your client code when you log in as you, the actual account that's hitting the database is the account that the web site is running under.

Thanks a lot for taking your time to answer me, despite the ridicilous tone I had..

It's in swedish so it's most likely rather jibberish to you, but it basically says "The server could not be found or is not available".

I run it on IIS however, which is why username and password confuse me.

Also, should I really use localhost as server when I'm running it local like this?

Thanks,

Jop

I believe you may have to change localhost to (local), and you need to add the SQL Server instance name in if it's running as SQL Express (or as a named database instance). Suppose the instance was called Jop, then the server name would look like (local)\Jop.

Thanks a lot. I finally solved it. I shouldn't use (local) but I searched around a little about the instance name and sh*t and it turned out there was a generated connections string I could use with some modification.
