OpenGL, for several reasons - I'll just list a few:
* easy to use inside winforms (even in C#, check the TAO framework)
* if you manage to crash it, windows will still be alive
* easier low-level manipulation of eg vertices (good for visualization)
* full access to all hardware features (the gpu manufacturer will make sure of it)
DirectX isn't "bad" for 3D visualization though, it's fine to use it.

Is there any free openGl control implementing basic actions for .NET or I have to design one by myself?

Hello,
I have created a datagridview using C# windows application and I am having formatting issues with the data once the datagridview has been populated. The way I have this set up is before I bind the data to the binding source I add a new row which contains combo boxes. These Como boxes are used to populate the new headers. Once the headers have been modified the data needs to be formatted to data types the system can handle. For example, the datagridview populates dates as mm/dd/yyyy 00.00.00 AM but I need to reformat this to mm/dd/yyyy. I have created a method that loops through each cell in the first row and captures the new header (which works) but when the code that is suppose to reformat the column runs, it doesn't work. the code I have to reformat the columns based on the logic used is dataGridView1.Columns[c].DefaultCellStyle.Format = "d";. However, this doesn't work. Can someone please help me? It is much appreciated. Here is what I have and if it is not enough then let me know and I can post more code.
private void button10_Click(object sender, EventArgs e)
{
if (radioButton1.Checked == true)
{
string[] newHeaders = new string[dataGridView1.ColumnCount];
int n = dataGridView1.ColumnCount;
int c = 0;
for (c = 0; c < n; c++)
{
newHeaders[c] = dataGridView1.Rows[0].Cells[c].Value.ToString();
if (newHeaders[c] == "A1ORDT")
{
dataGridView1.Columns[c].DefaultCellStyle.Format = "d";
}
}
}
else if (radioButton2.Checked == true)
{
//Add code for custom formatting
}
else
{
MessageBox.Show("Please select standard or custom formatting");
}
}

Hello 
I have soft of a half problem, where i know the cause of the problem, but don't know how to solve it exactly.
What i want to achieve: I want to check if outlook, excel and word are installed in the host computer when the user launches the program and inform the user if there are some complications.
My problem: I have application that uses excel, word and outlook. In every computer that has Office installed the program works and i even don't have to publish my application, instead copying the release folder is enough. But the application doesn't even launch on hosts, instead i get cut off very beginning and therefore i can't even show my informative messages, that don't have office installed and i get clr20r3 error.
How far im to solve the problem: I have found a problem cause in the following quote

Hi all,<br />
<br />
I have found the solution to this issue, it is due to dependancies. (I've just found out one of my employee's installed a second program onto the first virtual machine) This is why it gives a filenotfound exception as it is trying to load this program.<br />
<br />
When you use third party dll's that are not installed on windows by default the built in publishing tool inside VS.NET will not include these in the distributable it builds for you. I do not understand why i doesnt do this but i am switching all my distribution to Install Shield from now on.<br />
<br />
To fix your applications what you need to do is to look at your references (in solution explorer and in insertable objects) and make sure that you copy these dll's and dependancys onto the machine you want to install to and do a regsvr32 -i <dll><br />
<br />
I hope this helps you guys,<br />
<br />
Kind Regards,<br />

This post also explained shortly what i can do to solve this problem, tho it didn't help me much.
What i want to achieve: I would like to by pass this error and still be able to launch my program. And then show some informative messages to the user and take necessary actions.
What i have tried to solve the problem: I made sure that i had following 3 DLL files in my release folder and when i published they would be included.
Interop.Microsoft.Office.Interop.Outlook.dll
Interop.Microsoft.Office.Interop.Excel.dll
Interop.Microsoft.Office.Interop.Word.dll
So that all the DLL files for my dependencies in program would be there. And what happened was that i got a bit different error

I have also tried to dig into this problem, but in all the explanation there are things that i don't understand and therefore can't rinse out the right solution.
Summary: I hope i have given enough information so you would be able to suggest me with simple solutions
Thanks

Does the file (H:\Application Files\IOMailer_1_0_0_0\IOMailer.exe.manifest) exists?
|
|

|

thanks man, it helped cos i just didn't notice that folder when i copied the application.
tho i got another error which says that i have to install assembly stdole in GAC, but i don't want to bother you anymore, cos im sure im accapable of solving this problem on my own
|
|
|
|

Okey my problems are not really solved still.
I solved stdole.dll problem.
But now clr20r3 error came back and i can't run my setup in any computer either on the one that has office and on the one that has not.
But you already know the story of my problem from the first post and therefore i will not start repeating my self Smile and hope that some one has a solution for my problem.

I have an odd one - or odd to me at least.
public void Encrypt(Stream sIn, Stream sOut)
{
string Routine = "Encrypt: ";
if (key == null)
{
throw new Exception(Routine + EX_CRYPTO_NOKEY);
}
if (sIn.Length > int.MaxValue)
{
throw new Exception(Routine + EX_CRYPTO_TOOBIG);
}
sOut.Write(encAlg.IV, 0, encAlg.IV.Length);
CryptoStream encrypt = new CryptoStream(sOut, encAlg.CreateEncryptor(), CryptoStreamMode.Write);
byte[] abIn = new byte[sIn.Length];
sIn.Read(abIn, 0, (int) sIn.Length);
sIn.Close();
encrypt.Write(abIn, 0, abIn.Length);
encrypt.FlushFinalBlock();
encrypt.Close();
key.Reset();
}
public void Decrypt(Stream sIn, Stream sOut)
{
string Routine = "Decrypt: ";
if (key == null)
{
throw new Exception(Routine + EX_CRYPTO_NOKEY);
}
if (sIn.Length > int.MaxValue)
{
throw new Exception(Routine + EX_CRYPTO_TOOBIG);
}
int totalBytes = (int) sIn.Length;
=====>
=====> SEE BELOW
=====>
totalBytes -= encAlg.IV.Length;
CryptoStream decrypt = new CryptoStream(sOut, encAlg.CreateDecryptor(), CryptoStreamMode.Write);
byte[] abIn = new byte[totalBytes];
sIn.Read(abIn, 0, totalBytes);
sIn.Close();
decrypt.Write(abIn, 0, abIn.Length);
decrypt.Flush();
decrypt.Close();
key.Reset();
}
Replacing the bit marked ====> with the bits below
In Decrypt, if I try to read the IV from my encrypted file directly into encAlg.IV, the IV doesn't change.
sIn.Read(encAlg.IV, 0, encAlg.IV.Length);
If I read into a buffer first, then set the IV it works.
byte[] ab = new byte[encAlg.IV.Length];
sIn.Read(ab, 0, encAlg.IV.Length);
encAlg.IV = ab;
Any ideas?

maybe that IV buffer is not the right size when you try to read directly. where as when using ab you have set the array size to be what is required... I don't know this for sure thou
for example, does the following work?...
encAlg.IV = new byte[encAlg.IV.Length];
sIn.Read(encAlg.IV, 0, encAlg.IV.Length);
Life goes very fast. Tomorrow, today is already yesterday.

No. the new encAlg.IV is still all zero after the read. (And predicably enough the decrypt yields garbage as you would expect)
Read into a buffer, set the encAlg.IV to the buffer and the decrypt works perfect. Weird...

I am working on a program to aid in troubleshooting a clinical application we use in house. The application is a .NET program that runs in a terminal server environment. I would like to return a stack trace whenever a user presses a "help button." This button will take a screenshot and return a list of all running processes. I would also like it to return a stack trace of any of the LTCDB (the application) processes running. Is there a way of doing this?

Hi All ,
I have 50,000 entries on my Sql 2005 Table.I would like to know the first time each distinct objects gets in to my table.
Lets say object1 has 10 records on my table at diffrent date ,object2 gas 100 records on the table,object3 has 500 records in the table registered at different date.
I would like to reterive each objects with there first entry only,how would i do it?
Please advice.
THank you all
|
|
|
|
|
|
It's going to be something like
SELECT objectName, MIN(objectDateInserted) FROM yourTable GROUP BY objectName
where objectName is the column containing 'object1', 'object2' etc. and objectDateInsert is the column containing insertion dates of the individual records. MIN selects the first insertion.
Others will correct me. But yeah, it is a wrong forum.

Many thanks for your response.Its Much appreciated.
The problem i have is there is another column in my select statement.
SELECT objectName, MIN(objectDateInserted),SO_Name FROM yourTable GROUP BY objectName
Then It gives me to diffrent entry for diffrent SO_name for the same object1. However ,what i want is the minimum of the three all those in Time.
Please advice
Thank you once again.

I understand what you mean but unfortunatelly - I don't know. It doesn't seem like a difficult problem so maybe if you try your luck in some SQL/Database forum, you'll get the answer. I'm really not much of a database expert.
Sorry, H.

Hello frnds,
I am developing installer to deploy my application for that i am using VS 2005 Setup and deployment fascility.
I have my own desinged window form having a textbox and button for Browsing the folder.
the instance of above mentioned form is created inside install method of installer.
whenever i start installing my msi file i am getting the above form
containing textbox and browse button.
On click of browse button i have written folderBrowserDialog .showDialog
but Folder Browser Dialog does not display dialog window.
thanks in advance..

Hi there,
Well I think I've passed by this problem before,
As far as I know , the folderBrowserDialog is treated as an UI object , so you can't modify it from any function other than the main thread ( on the thread that created the UI element, which is the thread of your msi in your case )
In order to do this, the Control class (folderBrowserDialog) provides the Invoke method, which will take a delegate and execute it on the thread that the UI element was created on.
In order to use this:
1- one must declare a function that performs the UI operation.
2- create a method that will call the ShowDialog on the folderBrowserDialog object.
that's all , I hope this can be the solution for your problem as it was for me.
Good LUCK
