It assumes that you were wrong as it may not come 2 httpS in the url,
you may resolve this by sending it as a query string ,if you own this site.

string aa = "\document\test";
aa = aa.Replace("\", "\\"); --- this line C# doesn't like it??
I want to replace '\' in string aa to "\\". How to do it?

You have to escape your chars

I suspect the problem is that \d and \t are valid escape values, so you've not realised the problem. To put a \ in your string, either put two or, ( my preferred option ), use @. With @ at the start, everything is literal, the only escape is double quotes to do quotes.
string aa = "\document\test";
The value here is ocument test, where the spaces are a tab
string aa = @"\document\test";
string aa = "\\document\\test";
These both set the string as you'd expect

If you have it already and want it to be replaced now,you may use the StringBuilder class that will assure that it's been replaced.

string aa = @"\document\test";

<br />
string aa = @"\document\test";<br />
<br />
aa = aa.Replace("\\", "\\\\");<br />
<br />
aa = aa.Replace(@"\", @"\\");<br />
<br />
<br />
Trick:
If U want to use \ in strings U must duplicate it, or use @ before teh string.
I hope it helps.

Yeah so I created a nice little Web Service that returned a custom class called Site which has 3 strings and an int. I kept getting:
System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: The type PortalService.Site was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically.
at System.Xml.Serialization.XmlSerializationWriter.WriteTypedPrimitive(String name, String ns, Object o, Boolean xsiType)
And I used both XmlInclude and SoapInclude to no avail. So I said screw it and created a string with a delimiter that I could parse when it returned to the client. Perfect. Except now when I call the WebService, the webpage's graphics don't load completely and at random. I suppose this perhaps attributed to the fact that I just did <% Function() %> since the basic Repeater did not suite my needs. Any suggestions?

I get a compiler error that not all code paths return an error. I'm fairly new at C# so did something change from MFC to C#?
<br />
public bool ConfirmSQLServer()<br />
{<br />
String SrvrName;<br />
SQLutilz sie = new SQLutilz();<br />
<br />
IniFile ini = new IniFile("C:\\Larimore\\Prog\\LA.CFG");<br />
SrvrName = ini.IniReadValue("DATABASE","Server");<br />
ResultsLst.Items.Add("Database Server: " + SrvrName, 0);<br />
String[] SrvrLst = sie.EnumerateSQLServers();<br />
<br />
for (int i = 0; i<SrvrLst.Length;i++)<br />
{<br />
MessageBox.Show(SrvrLst[i].ToString()+ " " + SrvrName.ToUpper());<br />
if (SrvrName.ToUpper().CompareTo(SrvrLst[i].ToString())== 0)<br />
return true;<br />
else<br />
return false;<br />
}<br />
}<br />
<br />
<br />
Thanks

Take your return statements out of the for loop.
Example)
bool retValue = false;<br />
for (int i = 0; i {<br />
MessageBox.Show(SrvrLst[i].ToString()+ " " + SrvrName.ToUpper());<br />
if (SrvrName.ToUpper().CompareTo(SrvrLst[i].ToString())== 0)<br />
retValue = true;<br />
break;<br />
}<br />
return retValue;

C# sucks at working out that all code paths do indeed return a value, although in this case, you'll return no matter what on the first iteration.
You should set a return variable with a default value, and return it at the end, change it on the way through if need be. For example, I'd set a bool value to indicate success to false, and reset it to true only when everything had worked as expected.

Hmmm... I always had the feeling C# was rather clever doing this. Why exactly do you think C# 'sucks' in this point?
|

An example that hit me recently was when I was trying to use an if-elseif construct to return a different result for each value of an enum type. despite having a branch with a return for each possible value c# refused to accept that it always would return a value.

To be honest, I would think it would be more efficient to code it like I have. No memory is taken up by a BOOL in my code that you would in the earlier suggestion.
Thanks for all the help guys. Some things C# is really good at, other things it's not.

Because I've written code where all paths return a value, but they are all in an if/else situation, and the compiler has barfed.

hi all
anybody can help me to create a text file in c#?
thanks

Look in the System.IO namespace for lots of classes for reading and writing files.

string fn="c:\texfile.txt";<br />
System.IO.StreamWriter sw=new System.IO.StreamWriter(fn,false,System.Text.Encoding.Default);<br />
<br />
sw.WriteLine("Tis is a line in the text file!");<br />
<br />
sw.Write("This text placed to the currnt file pointer place in the textfile");<br />
<br />
sw.Close();<br />
It's quite simply enjoy!

Hi,
In my windows form, I have a set of CheckBoxes, which I am storing the selection as an integer value in the database and I am able to do that with CheckBoxes. But I have a groupBox with two radioButtons, I don't know how to read the bit values from it.
This is my GUI class....
CheckBox1.Checked = r.cSthA; //gets and sets the value for the
// checbox by reading the property
// from the class "r" given below.
// This is a different class
private enum rc : int
{
cSthA = 0x0001
};
public int Rac = 0;
public bool cSthA
{
get { return ((Rac & (int) rc.cSthA) != 0); }
set
{
if (value) Rac |= (int) rc.cSthA;
else Rac &= ~(int)rc.cSthA;
}
}
// How to set the property and read it for a groupBox.
I really appreciate ur help..
Thanks

If I populate a combo box manually with items, I can get the selected item using
comboBox.SelectedItem.ToString();
But now I have created a databound combobox, but cannot find out how to get its selected value.
comboBox.SelectedItem.ToString();
Returns System.Data.DataRow
and
comboBox.SelectedText.ToString()
returns "". Even though a value is selected.
How can I get the selected text/value of a datbound comboBox??

|
|

Well. Whats the problem here??
comboBox.SelectedItem contains the DataRow... just use it.

Does anyone know where I can find information on how LIMS are designed? Specifically I'm wondering how a user of a LIMS system can define Materials to test and test methods / results and the program store data correctly for each result type. The front end will be written in C#.
Here's an example of what I need to do:
I have a material id as Liquid 7 which we test regularly. The tests include maybe a moisture (float data type) and a solids (float).
Now we are getting a new material Liquid 9 with tests moisture, solids and Pass. Moisture and solids are the same as for Liquid 7, but Pass is a string based off a visual check of the liquid.
I don't want to manually create a new database table for each new raw material we receive and test. I want an end user to define the test name and test result type and my program somehow store this data in a database for retrieval and analysis.
I don't know how commercial LIMS implement this but if anyone has any ideas I could use them.
