Did you try this?
DataGridView1[5, a].Value == DBNull.Value

Hi,
According to the exception it is quite clear that CLR bumped into a null value while evaluating
"DataGridView1[5, a].Value"
what means "DataGridView1[5, a].Value.toString()" if "DataGridView1[5, a].Value" is null ??
You might not assume DataGridView1!=null nor a!=null nor DataGridView1[5, a].Value!=null
though the following test should solve your problem :
if (DataGridView1[5, a]==null or DataGridView1[5, a].Value==null)
{
///
}
Hope it helps

if (DataGridView1[5, a] == null)

Hello,
Vasudevan Deepak Kumar wrote: if (DataGridView1[5, a] == null)
I guess this will not help,
if this is true:
for temporary i did
string aaa = DataGridView1[5, a].Value + "D"; if (aaa.Trim )== "D")
its working but i dont like this way
All the best,
Martin

I think your grid must be having only 5 records from 0 to 4.
So its not geting the 6th record.

Hello everyone,
Previously, I think if I am using namespace ns1, and declaring and defining a public class cs1 using C# Class Library project, I have to name the output DLL name to be ns1.dll. I have this idea because I noticed that Microsoft names the DLLs, like System.dll for name space System, System.Data.dll for name space System.Data.
Now I tried that I can name the output DLL name to arbitrary name (not ns1), like mylib.dll. Then the applications which use the DLL still work.
So, I think the conclusion should be, we can use arbitrary name which is not related to namespace. Right?
thanks in advance,
George

I assume the name of the assembly does't matter as long as you added your assembly to your project and the contents in the assembly is not changed.

Thanks zion417,
I think you are also not following the naming convension which Microsoft does (e.g. namespace.dll). Right?

It depends on my project.Normally we follow the same convension .Root.Child1.. etc. I was just saying the name of the "assembly" done actually matter.

how to use contains method
I want to search more than one string like this
line.Contains("AssemblyVersion","AssemblyCompany","AssemblyProduct","AssemblyCopyright","AssemblyTrademark","AssemblyCulture")
how could i search??
plz reply if anybody knows
Thanks

Hello,
Other then Regex,
what you need is not implemented in the framework string class, AFAIK. (At least not in .Net 1.1)
The string class provides the IndexOfAny method, which only is able the search for chars.
But you could use a self written method!
Like this:
This method returns the startindex of the string which is found first.
public static int IndexOfAnyString(string TextToParse, string[] TextsToSearch)
{
int index=-1;
if(TextsToSearch!=null)
{
foreach(string actSearchText in TextsToSearch)
{
if(actSearchText!=null && !actSearchText.Equals(string.Empty))
{
index = TextToParse.IndexOf(actSearchText);
if(index>=0)
{
break;
}
}
}
}
return index;
}
In .Net > 1.1, you could use the "Contains" method instead of "IndexOf"!
Call it like this:
string mainline = "Hello codeproject world";
int index = IndexOfAnyString(mainline, new string[] {"msdn", "codeproject ", "blablabla"});
This is just a basic implementation of the problem.
You could add some more features like:
case sensitivity (true/false)
out param string, which returns the matching string
returning an array of int index values for all search texts
.
.
.
Hope it helps!

Thanks For reply..
I'm using like this
if (line.Contains("AssemblyVersion")||line.Contains("AssemblyCompany")||line.Contains("AssemblyProduct")||line.Contains("AssemblyCopyright")||line.Contains("AssemblyTrademark")||line.Contains("AssemblyCulture"))
{
line = string.Concat("// ", line ," // comment");
}
its working..
But its adding comment withount indenting means..
AssemblyProduct //comment
AssemblyProduct //comment

how i make indentation...
if you know then plz reply..
Thanks in advance

you can also use if statement
if (line.Contains("AssemblyVersion") && line.Contains("AssemblyCompany") && line.Contains("AssemblyProduct")........)

I want to get the WiFi information (eg. signal strength) from code (eg. C++, C#).
OS may be XP, CE5.0 or above.
I know it can be related to ndisuio.
Where can I get more coding information?
Thanks!

Hello folks,
I have a rather large image, whose size is around 6000 x 5000 pixels...
I would like to perfom image normalization and other such operations...which include some mathematical calculation for each pixel..
But when I do this on my image, it take about 20 mins to finish...
How to speed it up...??
Here is the normalization code which I am running..
public void NormalizeImage(ref Bitmap objBitmap, int iMaxColor)
{
DateTime dt = System.DateTime.Now;
System.Diagnostics.Trace.WriteLine(" Normalizing Image: " + dt);
int iX = objBitmap.Size.Width;
int iY = objBitmap.Size.Height;
int iMaxINTColor = 16777215;
try
{
for (int i = 0; i < iX; i++)
{
for (int j = 0; j < iY; j++)
{
int iPrevColorVal = objBitmap.GetPixel(i, j).ToArgb();
//if (iPrevColorVal < 0)
// iPrevColorVal = iPrevColorVal * -1;
int iNormalizedVal = System.Convert.ToInt32(Math.Pow((iPrevColorVal / iMaxColor), 1)) * iMaxINTColor;
objBitmap.SetPixel(i, j, Color.FromArgb(iNormalizedVal));
}
}
}
catch
{
System.Diagnostics.Debug.Assert(false);
}
DateTime dt2 = System.DateTime.Now;
System.Diagnostics.Trace.WriteLine("Done Normalizing Image:" + dt2);
}

Hi Safee,
The problem is the call to SetPixel. It's horribly slow. You can use the free .NET library FastBitmap[^] to speed up pixel operations, which will result in your algorithm being much faster.

Hey all, i need some help..
I'm using C# language for my project.. I'm having problems with my RTC program..
The program cannot make outgoing calls to the SIP server and VoIP phone..
But the SIP server and VoIP phone can call the RTC program..
This is the part of the code which enables the SIP server to connect with the program..
string bstrProfileXML = "<provision key=\"testing\" name=\"testing\">";<br />
bstrProfileXML += "<user uri=\"sip:102@152.226.136.17\" account=\"\" password=\"\" realm=\"\" />";<br />
bstrProfileXML += "<sipsrv addr=\"152.226.136.17:5060\" protocol=\"udp\" role=\"proxy\" />";<br />
bstrProfileXML += "<sipsrv addr=\"152.226.136.17:5060\" protocol=\"udp\" role=\"registrar\" />";<br />
bstrProfileXML += "</provision>";<br />
oProfile = oClient.IRTCClientProvisioning2_CreateProfile(bstrProfileXML);<br />
oClient.IRTCClientProvisioning2_EnableProfile(oProfile, RTCRF_REGISTER_ALL);
Anyone can help me??

Because your question involves intimate knowledge of this 3rd party RTC component, you may not receive a meaningful answer here. Have you tried posting your question in the RTC manufacturer's forums or support desk?
