Hi
I am working on Biomatric Solution Project.I am using SecuGen BSP Device for This purpose.Device return Fingure image data in string .I want to display this Fingure image into Picture Box Control. For This I kept The output string in Byte array and then i write it in Memory Stream and at last
create a bitmap to display image(at this stage i got error "Parameter is Not Valid")
Problem:-Code Give error when i create a bitmap to display image.
red line show the error point.The error syntax is "Parameter is Not Valid".
My Code is:-
try
{
//Create Device API Interface object
SECUBSPCOMLib.APIInterface objSecuBSP = new SECUBSPCOMLib.APIInterface();
long deviceID;
objSecuBSP.EnumerateDevice();
//Open Device
objSecuBSP.OpenDevice(2);
string szFIRTextData;
objSecuBSP.Enroll(null);
//Get Data of Image(Fingure Print) into a string
szFIRTextData = objSecuBSP.FIRTextData;
//Get string into Stream Format means into Byte array from string
byte[] arrBytes = new byte[szFIRTextData.Length];
int i = 0;
foreach (char c in szFIRTextData.ToCharArray())
{
arrBytes[i] = (byte)c;
i++;
}
// Open a stream for the image and write the bytes into it
System.IO.MemoryStream memStream = new System.IO.MemoryStream(arrBytes, true);
memStream.Write(arrBytes, 0, arrBytes.Length);
// Create a bitmap from the stream for Display it on Picture Box Control
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(memStream);
pictureBox1.Image = bmp;
memStream.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

Are you sure this stream contains a bitmap ? I'd have thought passing it as a string would cause it to null terminate in the wrong spot.

Wahoo!
I just did my first little Application that is of any use. Its a calculator that my friend uses for work, with some weird Calculations in it. But it works.
Anyway, I suppose I have 2 questions.
1. Is there a way to make just 1 Setup.exe file that can be sent without any other files that will install fine at the other end.
2. If not, Which files from the publish directory do I have to send to get the Application to work at the other end?
Many Thanks all
Tony

1 - not in C#, you also need the .NET framework
2 - yuo probably just need the exe and the manifest. Plus the framework.

Tony, just send an .exe file if it is not having any dependancy dll file.

You can embed the framework in the single setup file. So the framework also will be installed when the application is installing.

So I can just send the setup.exe? when I try copying it to a different folder and running it, I get an error.
<br />
The following error occurred attempting to install 'C:\Documents and Settings\Tony\My Documents\Visual Studio 2005\Projects\CostingCalculator\CostingCalculator\publish\Release1\test\CostingCalculator.application':<br />
"The system cannot find the file specified. "<br />
<br />
See the setup log file located at 'C:\DOCUME~1\Tony\LOCALS~1\Temp\VSD1BA.tmp\install.log' for more information.<br />
How would I embed the framework?
Cheers all

Hi friends,
how can i hide a column from a datagrid.suppose i use a store procedure having eight columns.
i want to hide the primary key column.how can i do that.
remember it is a windows application not web.
thanks
|
|
|
|
|
if u only want to display data.
then u should try using listview control
by using that u can easily hide/show the required columns.

Hi
Use below code :
<br />
dataGridView1.Columns[0].Visible=false;<br />
I can help you in other fields about DataGridView "freshonline2003@yahoo.com"
Bye

i am saying about datagrid..not datagridview.
|

define a dataset, a datatable, map all the columns of the datatable
while mapping, use mapping type as hidden for the column which you want to hide.

In the stored procedure avoid selecting the column that you don't want to display

please don't ask the same question twice, respond to my response on the same thread if you want to ask something more.
View/Bookmark brings up the manager, it has a button in the top left to add a bookmark.
this is something you should be able to work out, you won't break anythng by playing with the IDE

Oh, now I understand. There is no bookmark functionality on the site, I don't think. Your browser will bookmark pages for you.
What does this have to do with C# ?

Hi,
there is a Bookmark hyperlink on top of each CodeProject article (next to Print,
Broken Article?, etc), but not in the forum messages.
And you get a list of all your bookmarks through the "My Bookmark" hyperlink that
appears near the right top on all CP pages.
|
|
|
|
|
At the top of every article there is "toolbar", where you can bookmark articles. These will show up in "My Bookmarks".

Can anyone direct me to someplace that I can learn more about the forms that are built into .NET 2005?
My problem stems from the following: I have three arrays with ten places in them. I can fill both the first two with numbers and retreive them. With Console.Writeline I can show the first two arrays numbers, and the third arrays sumation of the first and second numbers. 
Example: Array1{0} = 15 plus Array2{0} = 45, and sums it in Array3{0} = 60.
I can display it in a console application with no problem. I need to display it in a messagebox. I can get the caption and the outputMsg to show in a messagebox. 
What I can't get is the set of numbers to show in the messagebox. This brings me back to my request. Can anyone tell me where I can find some more information on the windows forms, especially the message box? 
P.S. - Yes this is an asignment for school, and no I'm not asking for somebody to solve it for me. Just to head me in the write direction.
Thank you in advance.

Yes, keshav is right. MessageBox concept is very simple. If you want to learn your self then MSDN site and do some search there. I am ready to take you there if you need.
