pl help me to post some example codeing related to this...
thankss..
IntPtr hWnd = FindWindowEx(IntPtr.Zero, IntPtr.Zero, "Progman", null);
ShowWindow(hWnd, 0);
int intReturn = FindWindow("Shell_traywnd", "");
SetWindowPos(intReturn, 0, 0, 0, 0, 0, SWP_HIDEWINDOW);

It is really surprising that you can understand this code and then ask such questions.

He's obviously copying and pasting code from all over the web, and yet has no idea what he's doing. Remember the barcode login fiasco ?

Maybe it's some sort of experimental bot that's picking up code fragments from around the net, pasting them together, and then using keywords in them to post questions here...

That code snippet is horrible. You try to hide the ProgMan and Taskbar windows, mix up ints and IntPtrs, and use zero instead of a constant in the ShowWindow call. To answer your question, you put the startup code in the Main() method. But please, make that code cleaner. It burns my eyes
By the way, this seems to be a little threatening to a user. You should try to find a way to do whatever you're doing without hiding the taskbar (and desktop IIRC), because whatever code you use to re-show them again won't be executed if your program's process is killed by Task Manager or some other unorthodox method

how to hide MaximizeBox ?
|
|
|
|
|
Hi,
Form.MaximizeBox=false; almost hides it. Chosing another FormBorderStyle may hide it completely (as well as other parts of the title bar).

hi...
i am saving images in a DB
when i try to open them from the database i have an error
the code:
SqlConnection con1 = new SqlConnection("DATA SOURCE = MAX_TOSHIBA ;Initial Catalog= nodule ; Integrated security = True");
SqlDataAdapter adp1 = new SqlDataAdapter();
SqlCommand com1 = new SqlCommand("SELECT the_pic FROM pic where pic_id='" + chos_pic_id.ToString() + "' and pic_no='" + chos_pic_no.ToString() + "'",con1);
adp1.SelectCommand = com1;
DataTable t__1 = new DataTable();
adp1.Fill(t__1);
byte[] by_ = (byte[])t__1.Rows[0][0];
FileStream FS1 = new FileStream("image.jpg", FileMode.Create);
FS1.Write(by_, 0, by_.Length);
FS1.Flush();
FS1.Close();
pictureBox1.Image = Image.FromFile("image.jpg");
the error appear in the last line saying "out of memory"
thanks in advance

Hi,
some comments:
1. you are not running out of memory: GDI/GDI+ and .NET generate an "Out-of-Memory" condition when the data is not a valid image.
2. the problem can equally well be in the piece of code that puts the image in the database; you really should compare those two snippets for almost identity.
3. I suggest you log your SQL commands, and the length of the byte arrays
4. you don't need to create an image file to get it from database to PictureBox; a MemoryStream and Image.FromStream() should suffice.
5. Flush and Close does not make much sense, since Close implies a Flush; Flush is useful sometimes when you do not want to close right away.

hi, thank you for your reply..
i tryed the memorystream ,and i did not work ,it give me the same error !!
the intresting thing i found that the byte numbers it give the error after is 13!! i realy dont know why
i have tryed many images but the same error with the same number 13!!
any way you wanted me to check the input method, i do not find any thing in it , here it is
byte[] data = null;
FileInfo fInfo = new FileInfo(sPath);
long numBytes = fInfo.Length;
MessageBox.Show(numBytes.ToString());
FileStream fStream = new FileStream(sPath, FileMode.Open,FileAccess.Read);
BinaryReader br = new BinaryReader(fStream);
data = br.ReadBytes((int)numBytes);
thank you verey much for your time and effort

Hi,
there is no need for you to show us how a MessageBox.Show statement looks like.
What YOU should do is compare all the different length/size informations you have, and make sure they are all the same, the first to deviate will point you at the (first) problem. Here are all the lengths:
- the file size as shown by Windows Explorer
- the byte[] length when you have read it in in the code that will put it in the database
- the database tools you use should allow you to investigate the size of a specific record and field
- the byte[] length when you get it back out of the database
If all the above are the same, chances are good your last byte[] really contains an image, and you will be able to convert.

all the images that i load have 13 bytes (where i use the above code)
i do not know how to check the no. of bytes in the (sql 2005)
thanks

A_A wrote: all the images that i load have 13 bytes
which is clearly wrong. How many image files do you own that small?
Probably none.

Neither do I, I know how to use PhpMyAdmin to watch fields and field sizes on MySQL tables, I don't have SQL Server where I am right now.
Suggestions:
-dump those 13 bytes in hex, fat chance they form an ASCII string because you called ToString() somewhere, possibly implicitly.
-check your code, try to figure out whether save-to-DB or load-from-DB are the culprit.

finally, i figer it out
i have to use a code similar to this
main idea is to write the type when we insert the image as "SqlDbType.Image"
SqlConnection con = new SqlConnection("DATA SOURCE = MAX_TOSHIBA;Initial Catalog=nodule; Integrated security = true");
string sql = "INSERT INTO pic (pic_id,patient,id,the_pic,pic_no) values ('" + j + "','" + txt_patient_name.Text + "','" + 0 + "', @a,'" + 0 + "')";
SqlCommand cmd = new SqlCommand();
SqlParameter sp = new SqlParameter("@a", SqlDbType.Image);
sp.Value = by_img;
cmd.Parameters.Add(sp);
cmd.CommandText = sql;
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
con.Close();

Hi,
I made a view from a few tables. I then imported that view into my Entity Data Model. The EDM assigned Entity Key = true to a column in the view that is not a primary key (the column is not a primary key in the view, and it is not a primary key in the table the view gets it from).
Why does the EDM do this? It assigned Entity Key = true to a value that IS an actual primary key (in the table my view looks at) and also to a value that ISN'T a primary key. I can't figure this out. Can anyone help me out?
TIA
PS -- I apologize if this is not the right forum, but since in the EDM I am dealing with C# code, I thought I'd post it here.

I can only think, this is not a fact, just my thoughts, that it is trying to create a form of compound key. All EntityTypes must have a key and so it is attempting to create a compund key that it thinks will be unique.

Thanks for your reply.
If this is the case, how would I get around it? If I set the column to NOT be a key, I get a mismatch error, suggesting that both fields (EDM and my DB) must be keys.

I very much regret that, I have no idea. I am only just starting out on the EF Highway, which is why I could still remember the stuff, in my previous post. Give it a month or two and I'll have forgotten that as well.
