Thanks all the answers! I think your answer Guffa, is correct, I wasnt thinking in an object orientated fashion.
I think I know how to do this now, I think I need to find a great book on OO and learn it!
Cheers

Hi
i'm sorry to post here, because i don't found discussion board for sharepoint in codeproject.
my question is that how to create custom calendar type and add it to sharepoint calendar types list (in regional setting page).
the better way to understand what i want to do is that you can see this http://csharptuning.blogspot.com/2008/09/persian-calendar-for-sharepoint-2007.html[^], it have some picture which display persian calendar that exactly i need it, and it does not exist in standard sharepoint calendar types, hence, i must create and add to sharepoint myself, but i don't know how to create it ?
do i must create a web part ?
do i must create a feature ?
do i must create field type/Control ?
and ..... ?
Thanks

I have two methods on a form. I want to run 2nd method only if 1st method is loaded through the background worker. For instance
Form1
{
Method1();-->loading through the background worker
Method2();-->how can i make sure if background worker is done with Method 1 then run any code after the Method1();
}

You could use static boolean(?) field in the class to indicate if the work is done. Just remember to use lock when modifying the field.

Events? Create an event, fire it at the end of Method1, and call Method2 in the callback function

What was happening is that sometimes the webbrowser1 couldn't load the document and i get the default html error page inside the webbrowser1. I want to load wb2 only if a html document has been fully loaded in webbrowser1 then load it in wb2. Can you please provide me some e.g for be better understanding too
Form1.cs
{
webBrowser1 = new WebBrowser();
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
path = "c:\a.html"
webBrowser1.Navigate(path);
Controls.Add(webBrowser1);
void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if (((WebBrowser)sender).ReadyState == WebBrowserReadyState.Complete )
{
//once the document is completely loaded
doc = webBrowser1.Document.DomDocument as mshtml.IHTMLDocument2;
doc.designMode = "On";
if (!webBrowser1.IsBusy)
{
wb2 = new WebBrowser();
wb2.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler (wb2_DocumentCompleted);
wb2.Navigate(path);
}
}
}

Ouch, apparantly its a pain in the arse to get any error codes from the webbrowser control. The 'best' solution is apparantly this:
http://msdn2.microsoft.com/en-us/library/system.windows.forms.webbrowser.createsink(VS.80).aspx[^]
Set up your browser control like that, and use the NavigateError event. If you get a callback for the event, then the page has not loaded correctly, so you'd want something like:
bool error = false;
wb1_NavigateError()
{
error = true;
}
wb1_docComplete()
{
if(complete && !error)
wb2.Navigate(...)
}
There might be easier ways (there damn well should be) but i couldn't see them.

I have recently installed Visual Studio 2008 Standard Edition. I tried to add a report to a project and when I drag the ReportViewer to the form, it just puts it at the bottom and does not show it on the form. It also does not show the triangle in the corner to select the report. What am I doing wrong?
|
|
|
|
|
Are you sure that you are using ReportViewer from namespace Microsoft.Reporting.WinForms and not from WebForms?

Yes, the project was originally a VS 2005 Express Project. If I create a new project, I can add a report viewer to a form but it will not let me add a new form to this project and put a report viewer on it.
|

Sounds like a problem in references or in project file.
Could you reconstruct the project, meaning create a new project and add all references needed, then add all existing classes.

The project is rather large so i just created a new dll for the report viewer form and referenced it in the old project. That seems to be working. Thanks for your help.

No problem, your solution should also work fine.

Hi,
I'm having difficulty getting a section of an app.config file to show as encrypted. I run the code and get no errors, but the section does not encrypt. Any help would be appreciated, I've tried other implementations from other posts here with same results:
using System;
using System.Windows.Forms;
using System.Configuration;
namespace AppConfigRedux
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnUnprotect_Click(object sender, EventArgs e)
{
UnProtectSection("connectionStrings");
}
private void btnProtect_Click(object sender, EventArgs e)
{
ProtectSection("connectionStrings", "DataProtectionConfigurationProvider");
}
private void ProtectSection(string sectionName, string provider)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(System.Windows.Forms.Application.ExecutablePath);
ConfigurationSection section = config.GetSection(sectionName);
if (section != null && !section.SectionInformation.IsProtected)
{
section.SectionInformation.ProtectSection(provider);
config.Save();
}
}
private void UnProtectSection(string sectionName)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(System.Windows.Forms.Application.ExecutablePath);
ConfigurationSection section = config.GetSection(sectionName);
if (section != null && section.SectionInformation.IsProtected)
{
section.SectionInformation.UnprotectSection();
config.Save();
}
}
}
}

Greetings again!
Can anyone please explain how to use the anonymous constructor with Dictionaries?
eg.:
public static Dictionary<string, UIElement> _controlList = new Dictionary<string, UIElement>()
{
};
Thanks in advance!
|

|
|
|
public static Dictionary<string, UIElement> _controlList = new Dictionary<string, UIElement>()
{
{ "Key1", value1 },
{ "Key2", value2 }
};

float a = (float)93.3;
float b = (float)2.3;
float c = a + b; // at this moment c = 95.60001;
Why? I meet this strange behavior not only in C#, but also in Javascript, Actionscript and PHP.

in addition to Dan's link, did you know you can declare a float as a literal by suffixing with an 'f' and save the expense of casting from a double (or int).
float a = 93.3f;
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

I try to make it short:
If you compute float numbers, the computer uses "MachineNumbers" which are to a certain level adequate. So the computer has internal numbers which are taken when given a float to compute.
e.g the Machinenumbers are
0.1,
0.2,
0.3,
0.4,
0.5,
1,
1.2,
1.5,
2,
2.4,
2.5
now you pass the number 1.2 -> computer takes 1.2 because it exists
then you take 1.3 -> computer takes again 1.2 because it is the nearest "MachineNumber"
you summ them and allthough there would be a "MachineNumber" 2.5
the computer computes 1.2 + 1.2 and you get the nearest "MachineNumber" which is 2.4
That's been very simplified, but I hope that helps

If you want to do floating point math, I've found that using the decimal type is more precise. Try it this way:
decimal a = 93.3M;
decimal b = 2.3M;
decimal c = a + b;
You should end up with precisely 95.6.
If you need to, you can follow that up by casting the result to a float or double as need be.

The caveat to using the decimal type is that unlike floats it's not implemented in hardware directly and is significantly slower to use as result. This isn't a problem if you're doing light computations, but if you're doing larger amounts of calculation working within the limits of native floating points may be needed.

To further and agree with your statement, decimal should only be used for financial or monetary values in .NET. At least that is my rule of thumb.
