Wouldn't you use the Enabled property on your sub items to achieve this behavior?

Check the connection string.
If SQL Server, check the SQL Server Browser service.
Check the firewall.
If all else fails, use a Web Service.

What is the problem to run in windows 7 64 bit C# application (compiled on Vista 32 bit VS2008 .NET 3.5) which uses PInvoke to run native function from 32 bit Dll.
Exception is System.BadImageFormatException Attempt to load application having bad format (HRESULT: 0x8007000B)

You can't use a 32 bit dll in an 64 bit application (and vice versa).
I'm not sure about native dlls but I think they behave the same.

As Covean said, you can't use a 32bit dll form a 64bit application.
By default, a .NET application run according to the O.S. (so, in a 64bit systems run as 64bit application).
You have to force your application to run as 32bit by changing the "Platfor Target" value in the Build properties of your Visual Studio Project.

If you have a 64 bit .NET application attempting to run a 32 bit DLL, you can change it to run in 32 bit mode by using the corflags command. It's detailed here[^], but basically you need to run
corflags myassembly.exe /32bit+

that seems to be the only solution to avoid recompilation, many thanks!

Hi,
When I Insert data in my Access Database show error i use this query
INSERT INTO trans (date,heads,debit,credit,descp) Values('2/8/2010','Jawad','0','9000','UNWASHD')
Table Trans
Feild....................Datatype
id......................AutoNumber
Date....................Datetime
Heads...................text
debit...................number
credit..................number
descp...................text
ERROR
"SYNTAX ERROR IN INSERT INTO STATEMENT "
Plz Help Me

Date is a DateTime, you're treating it as a string.
debit & credit are numbers, you're treating bpth as a string.
Access, i think, uses # to denote a date in place of the quotes for strings, and numbers just dont have any quotes at all. hence:
INSERT INTO trans (date,heads,debit,credit,descp) Values(#2010-08-02#,'Jawad',0,9000,'UNWASHD')
|
|
|
|
|
Same Error 
|
|
|
|
|
I'm not sure about access but you shouldn't use columns with names like 'date' because this is can also be
a datatype in this database.
Greetings

And if you have to use such names, put them in square brackets [].
Next, use a parameterized query, that will also handle the date/time problems.
INSERT INTO [trans] ([date],[heads],[debit],[credit],[descp]) Values(?,?,?,?,?)'

Hi guys
I want to redicet a web page when user click on button in window based application using C#,
Like we do in asp.net "Response.Redirect("http://www.codeproject.com").
Is it possible and how
Thanks & Regards
Shafiq.....

Do you want something like
System.Diagnostics.Process.Start("www.codeproject.com");
|
|
|
|
|
Hey Goutam
Thank you. Its working fine.
Now i am asking little more if the page is already open and button click can we reload the same page
instead of opening new window. it will be helpful for me.
Thanks again

Hi, Everbody.
i have writen c# Artifical intelliget Neural Network. I have 500 count dataset which is normalized -1 and 1 and.i have used learning rate and momentum coefficient .
i teaching my network with 400 count dataset. Network have 5 inputs and 5 outputs. my output is setuped as 00001/00010/00100/01000/10000
when my network teched with 10000 iterations and 400 datasets, my output have a problem.
my network teached in last class of 10000 so when i tested my datasets , output only have been predicted as true class of 10000.
as result my code can only learn last class and other classes can not predicted or poor predicected
Example Test and Learning dataset

My trainin code blok is as folowing show

for (int nf = 0; nf < 400; nf++)
{
mmse += hesaplas(ndata, nf);
trains(nf);
}
mmse = 0.5 * (mmse / 400 * 5));
if (it % 100 == 0)
{
yazs.WriteLine(mmse.ToString());
yazs.Flush();
}
it++;

Firstly, when you post code, use the "code block" widget rather than the "inline code" - it preserves the formatting and makes it easier to read:
int iterasyon=100000;
while (it = 0.00001)
{
mmse = 0;
mae = 0;
for (int nf = 0; nf < 400; nf++)
{
mmse += hesaplas(ndata, nf);
trains(nf);
}
mmse = 0.5 * (mmse / 400 * 5));
if (it % 100 == 0)
{
yazs.WriteLine(mmse.ToString());
yazs.Flush();
}
it++;
}
Secondly, if you are going to post code, make sure it compiles. That won't: it will complain about
while (it = 0.00001) "Cannot implicitly convert type xxx to bool"
Even if it did, it would execute the outer loop either once, or an infinite number of times.
Thirdly, don't use magic numbers: how do you know you have 400 entries? What is the
mmse = 0.5 * (mmse / 400 * 5));
supposed to do?
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Three things (over Original Griffs Reply)
1. Is there any correlation beween the input an the output (I cannot see any)? if not, the NN is not likely to find it.
2. How are you training the network, your code is hard to read. If you are repeating outputs 1,0,0,0,0 (400/10000?) times at the end of trainging, you are probably annealing the network to give this result no matter what. You should cycle through many outputs.
3. It is possible to overtrain a NN!
I'd start with something simpler to test you NN code:
1 Input 0 -->360 , and train output to sin
1 Input 0 -->360 , and train output to x^2
2 Inputs, train to Logical Opertors (remember the XOR problem)
3 Inputs, result = i1 * i2 * i3
Then test on a real dataset.

Firstly Thanks interest.
my dataset is folowing is that:
data is 5x400 matrix
b_cikis is 5x400 matrix
[...
long data removed
...].
int iterasyon=100000,it=0;
while (it = 0.00001)
{
mmse = 0;
mae = 0;
for (int nf = 0; nf < 400; nf++)
{
mmse += hesaplas(data, nf);
trains(nf);
}
mmse = 0.5 * (mmse / 400 * 5));
if (it % 100 == 0)
{
yazs.WriteLine(mmse.ToString());
yazs.Flush();
}
it++;
}
