Hi,
Im trying to find out the simplest way to store variable values in a file (text or otherwise), as well as being able to read specific areas of the file in order to retrive the values and implement them into a windows form control like a textbox or something. The StreamReader and StreamWriter class works but I dont know how to read specific lines like line number 4 or so. Here is my code:
<pre>
StreamReader sr = new StreamReader("configFile.txt", System.Text.Encoding.Default);
string s = null;
while ((s = sr.ReadLine()) != null)
{
if (s.IndexOf("Name:") != -1)
{
// textBox1.text = s;
break;
}
}
sr.Close();
</pre>
The issue is that I cant select what to search for by line number. All i need is a simple way to add textbox values to a text file where each texbox has its own line in the text file, and I can call up the text file at a certain line of the file and read the contents/make it the textbox text. The data is numerical. I came across hash tables but I do not know how to implement them/save them to a file.

One approach is to use a xml file.
Lots of examples on the web of how to do this.
Try looking at this[^]

Awesome advice! Thnks! Here is a website for anyone who is curious as to how to work with XML from the gorund up. Very comprehensive tutorials.

the simplest solution probably goes like so:
- keep key,value pairs in the file, one per line, all keys unique, key and value separated by some symbol (= seems the obvious choice);
- read all lines with File.ReadAllLines
- inside a foreach loop, split the line using string.Split('=',2), use the first part as a key, the second as a value, and stuff that into a Dictionary
Done. Less than 10 lines of code.

Possibly dumb question but how do I use the key you stated? I know its an identifier for the value string but do i just use my code to search for it? Like <code> if (s.IndexOf("fn:") != -1) </code> ? or what?

You create the dictionary like so (omitting error handling):
Dictionary<string, string> dict=new Dictionary<string, string>();
foreach(string s in File.ReadAllLines(path)) {
string parts[]=string.Split('=', 2);
dict.Remove(parts[0]);
dict.Add(parts[0], parts[1]);
}
You look up a key's value by using the key as an index to your dictionary, like so:
string name=dict["Name"];
You enumerate all key-values (maybe not in original order!) like so:
foreach (KeyValuePair<string, string> kvp in dict) {
log(kvp.Key+"="+kvp.Value);
}
You could also prepopulate the dictionary with default values for some keys:
dict.Add("Name", "Jef");
dict.Add("Occupation", "Software Engineer");

Is the file physically saved anywhere in order for me to acess it later? if so, how do I bring up a dictionary object from a file?

Hi,
you could save settings to disk by creating a loop, similar to the foreach I have shown; and later reload just like you load the first time.

I am testing out using Exchange Webservices to post tasks to the current user in a corporate intranet.
The code below works when I run it through Visual Studio 2008 debug mode, but when I publish it to the intranet site, it bails with the following error:
Microsoft.Exchange.WebServices.Data.ServiceResponseException:
When making a request as an account that does not have a mailbox, you must specify the mailbox primary SMTP address for any distinguished folder Ids.
I have disabled anonymous access to the website and have it set security to Integrated Windows Authentication.
As you can see below, I am passing the default credentials to the web service.
What am I missing here?
Any help will be appreciated.
public class ExchangeTask
{
ExchangeService myService = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
public ExchangeTask()
{
ServicePointManager.ServerCertificateValidationCallback = delegate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
return true;
};
myService.UseDefaultCredentials = true;
myService.AutodiscoverUrl(EmailAddressToFind);
ServiceURL = myService.Url.ToString();
}
public void SendTask()
{
Task myTask = new Task(myService);
myTask.Body = "This is a reminder task that has automatically been set by ExchangeWebservices";
myTask.DueDate = DateTime.Now;
myTask.ReminderDueBy = DateTime.Now;
myTask.StartDate = DateTime.Now;
myTask.Subject = "Event Reminder Task";
myTask.Save();
}

Just in case anyone ever looks at this question again,
The solution was to put <identity impersonate="true" /> in the web.config file under <system.web>
|
|
|
|
|
I'm having same problem.
You can try adding: <identity impersonate="true"> in the web config.
If I hardcode a user, password, and domain it works fine, but trying to get cached credentials seems hopeless.

I have the following xml:
<Resume>
<Details>
</Details>
<Contacts>
</Contacts>
</Resume>
how can I add childs to the Contacts using C# but with referring to the <Contacts> by name not by ID?
I want to add:
<Contacts>
<Contact ID="xxxxxxxx">
<Category>my category</Category>
<Number>my contact number</Number>
</Contact>
</Contacts>

You can use c# DOM to access the XML or DHMTL.
Try this:

As I already said, look to XPath.
If you load your XML into an XmlDocument, you can get the desired contact by doing:
xmlDoc.SelectSingleNode("/Contacts/Contact[@ID='xxxxxxxxx']");
Then, you have a reference to the node into which you can add subnodes.

Hi,
I am fairly new to programming and I am making member registration apllication.
The main form contains a DataGridView with all the checked in members. The DataGridView connects to a
stored procedure. This main form is also the start-up form.
In the search results form I can check in / out a member. This done by clicking a button that calls a stored procedure.
Now for my question:
After I click the checkin / out button I want to update the DataGridView in the main form.
I don't seem to be able to make this work.
Below is the code that I use.
The following method is placed on the main form. This is the method I want to call from the other form.
public void FillDataGrid()
{
this.aLL_CHECKED_IN_MEMBERTableAdapter.Fill(this.on_target_v1DataSet.ALL_CHECKED_IN_MEMBER);
}
I want to call this method through the following code, this code is located on a different form:
public void btnCheckIn_Click(object sender, EventArgs e)
{
Procedures.CallStoredProcedure.CHECK_IN_MEMBER(this.lblNumber.Text);
CheckInOut(this.lblNumber.Text);
frmMain cls = new frmMain();
cls.FillDataGrid();
}
Does anyboady have any ideas how I can tackle this?
Regards,
Paul Stol

Hi to all! I'm having the following problem and I would like some help on trying to solve it.
I'm trying to correct a problem I detected in a code from a project I'm working on (the code is not mine and since the person who made it is no longer in the team I have no way of knowing why this was made this way).
I've spoted a cast from double to long that doesn't seem to work out very well. The idea is to convert the double value to a long so that it can be compared between two other longs (max and minimum values in a specific scale). The code is something like this:
minValue = 56;
maxValue = 70;
value = 55.99.
if ((long) value >= minValue && (long) value <= maxValue)
{
....
}
The problem is that the cast makes value to be 55, instead of 56. Checking other alternatives, I saw Convert.ToInt64, that, for this example works. However, it does not work the way I wanted if the value is say, 70.5, in this case I'm stuck with 70, when I would like to have 71, like I saw on MSDN ("If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.").
Can anybody point me to the correct way of converting a double to long, without this problem with rounding the even numbers?
Thanks in advance!

I know it doesn't answer the question exactly as it was asked but...have you thought of reversing the conversion for comparison?
if(value >= (double)minValue && value <= (double)maxValue) "I need build Skynet. Plz send code"
