Did you resolve this problem? We have this same prombem on one project.
Error 1 The call is ambiguous between the following methods or properties: 'Microsoft.DirectX.DirectSound.WaveFormat.WaveFormat()' and 'Microsoft.DirectX.DirectSound.WaveFormat.WaveFormat()'
Error 2 The call is ambiguous between the following methods or properties: 'Microsoft.DirectX.DirectSound.CaptureBufferDescription.CaptureBufferDescription()' and 'Microsoft.DirectX.DirectSound.CaptureBufferDescription.CaptureBufferDescription()'
Project compiles fine but IDE show this annoying error all time when you toutch code after rebuild.
You can get this with Microsoft.DirectX.DirectSound.WaveFormat waveFormat = new Microsoft.DirectX.DirectSound.WaveFormat();
I think this cause by some Ms DLL:s. Maybe some reason this same namespace some also from another dll than C:\WINDOWS\Microsoft.NET\DirectX for Managed Code\1.0.2902.0\Microsoft.DirectX.DirectSound.dll Or there is some kind version confict.
Anyways looks that this is some kind bug that this cannot show why it give this error.
And it is not any kind new thing that DirectSound is full of bugs. Secondarybyffer.PlayPosition and CaptureBuffer.GetCurrentPosition give some times random "Application Exeption" exeptions when computer is on heavy load.
Most of buffer pointers are broken so if name is read position it can mean that it is inner buffer write position so you must read at least one block behid of it or you get random null bytes. etc etc. So when you program with ds just keep it mind that is something does not work it is about 50%/50% possibility that bug is on ds not on your code

Hi,
Seem to be very simple but it's not working with following conversion methods.
Trying to convert from string to integer 0's missing in the Output.
string strInput = "06461";
int iResult = Convert.ToInt32(strInput) (or) int iResult = int.Parse(strInput);
Output : 6461 (note 0's missing)
How to get the zero also in the output as 06461.
Reg,
Subbu

|

That is normal: an Int of "06461" = 6461 (you don't put 06461 in a calculator, do you ?  )
Keep the number as a string to show the leading zero's.

Thanx for your reply.
How to keep that as a string and expand it.
Example: string strInput = AD01234-AD01237;
This need to be Expand like AD01234,AD01235,AD01236,AD01237.
- Spliting the string in to 2 with -(hypen)
- From 1st string process from the last and get only numbers and vice versa.
- finally by using the For loop process from starting Number to end will be expanded.
But in this case need to convert to int then only it can be possible. how to achieve this?
Reg,

You can split a string like this:
string[] ArrayOfStrings;
string s = "AD0001-AD0002-AD0003";
ArrayOfStrings = s.Split('-');
For the rest I not sure what u mean...

Use an explicit format string when you print the int:
int i = 6461;
Console.Writeline(i);
Console.WriteLine(i.ToString("D5"));will print:
6461
06461

Thanks for your quick response.
But one question how to get the final value as a integer rather than string. Any Other Option?
int iResult = 06461; /// Output.

Oh boy. 
An integer is a number. Like any number, it can have an infinite number of zeros in front of it. Take your house, or flat number - let us say it is six, and the address is Lemon Street. You live at 6 Lemon street. You also could say "I live at 0000006 Lemon Street, and your letters would still arive - but the postman might think you are a little wierd.
You can happily tell Visual studio:
int i = 000000000006461; or
int i = 6461; or
int i = 0006461; etc., etc. They all mean the same.
A string representation of a number is more like a telephone number: "0123 456789" is a different number to "123 456789" because the exchange will not see it as having an area code, as the leading zero is missing. But, you cannot add two telephone numbers together!

You can't. It's impossible.

Or
string.format("{0:00000}", value);

yes, sure. and how many zeroes are missing? 1? one hundred?
2.
you could (I don't say "should") do what you want with strings and characters, i.e. come up with a method that "increments a string". This is how it would go:
a. copy the original string;
b. look for the rightmost digit that you haven't processed yet;
c. add one to it i.e. replace '0' by '1', or '1' by '2', etc
d. if in step c you replaced '9' by '0' then goto b
e. done
with possible refinement: if b fails, prefix a '1'

Hi
Can anyone tell me how I can download the first 1000 kb and last 1000 kb of a file in C#?
When downloaded, the file should just be deleted.
Have no clue on how to do this.
Thanks in advance
|
|
|
|
|
You can open the file using a stream and read the first and last 1000 Kb of the file. You can store that data in a seperate file.
|
|
|
|
|
I don't need to store the data - actually, the downloaded bytes should just be deleted afterwards.
Thought about doing something like this:
reader.ReadBytes(1000); reader.Position = (file.Length - 1000); reader.ReadBytes(1000);
Would that work? And what is the file is smaller than 1000kb?
|
|
|
|
|
If the stream is seekable, you're pretty close.
I think, if the stream is smaller than 2000 Kb you should read the entire file? Else you would copy duplicate data and (if the file is less than 1000 Kb) cause an exception.

Hello guys.
I would like to know how to extract the mathematical
expression from a string and compute the result.
Sample: The user will type 5 + 2 - 3 * 4 which will be in a string format.
Then the result will be assigned to a double variable.
Also, the user can include parenthesis in the expression: 5 + (3 / 9)
Thanks a lot.

In fact you can have a simple to a more complete solution...
Parsing grammar is based on definitions, for instance BNF, ABNF...
In your case, you can write a simple peace of code in order to have your expression parsed.
But if you want to have a more complexe handling use this pointer and check the section 7.2

One approach is to put the expression in a binary tree with numbers (or variables) at the leaves and operators at the interior nodes. Replace higher-precedence operators (and parenthesized expressions) with subtrees first.
To evaluate, do a postorder traversal, applying the operator at each interior node to the values obtained from its two subtrees.
When you're done, the result will be in the root node.

Hmmm... looks like a teacher assigned an RPN assignment yesterday.
See my response here[^].

|
|
|

I think without explicity declaring the order of precedence of operator execution ... i.e. : is this infix, postfix, RPN ? ... you cannot begin to respond to this question.
There are some math expression "parser" articles around CodeProject; try this one : [^].
