use the ToString method:
int i = 7;
string s = i.ToString();
string s2 = ((int)7).ToString();
|
|
|
|
|
int myValue = Convert.ToInt32(myString);
string myStringValue = Convert.ToString(myValue);
protected internal static readonly ... and I wish the list could continue ...

You'll need to compile your dll using the .NET compact framework.

string zipFileName=@"d:\sample.txt";
System.IO.FileInfo file = new System.IO.FileInfo(zipFileName);
if (file.Exists)
{
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.WriteFile(file.FullName);
Response.End();
}
else
{
Response.Write("This file does not exist.");
}
The above code works pretty good for file download but if I click 'cancel' or 'open' button in the "download" dialog box it shouldn't insert the download time in to the database and if I click 'save' it should save in to database.Is it possible?

Hello,
I have the folowing code for SAVE button''s event handler of my Window's form's binding navigator. Now, When I change any row, add or delete and after that when I save, it shows no error and for the whole time the application is alive, the data grid is reflecting my actions. Ok, but after that when I close the form and then Start that application again, I see no changes has been made to my database and datagridview is showing the old data. When I explore the physica database after that, I see no changes at all. I have tried a lot of ways to find out why !! I also experimented with both value (True and false ) of the Table Adapter property : GenerateDBdirectMethods.
try
{
this.Validate();
this.jobBoardsBindingSource.EndEdit();
this.job_BoardsTableAdapter.Update(myDataSet.job_Boards);
lblStatus.Text = "Job boards Updated Successfully : " + DateTime.Now.ToString();
}
catch (System.Exception ex)
{
MessageBox.Show(ex.Message,"Update failed");
}

Hi,
I have many projects in my solution..
All have been localized ...
The problem which i am facing is in one project, i.e. when i change the language for the application at run time.. every thing works fine except that none of the form under this project gets localized...
ex: Solution
Localization Manager
Project 1
Project 2
Project 3
Project 4
Now forms of project 4 does'nt show up culture specific captions where as all other form does that fine!!!
What is the cause of the problem and how could this be solved????
Thanks in Advance
Aditya

I don't know if it can be, but we in a project have problems with the Resources files, because the data inside weren't refreshed. So we did changes but we didn't see the text.
The solution was to create a Pre-Build Event to Delete all the "bin" and "obj" of the projects that contained .rex and .resources files.
with this everytime we compile the files were deleted and then refreshed.

I have a textbox on my form and I want if you enter a certian thing, the for will do something. Here is what it is:
I have the textbox and a button. If you type the following data in textbox, the button will become enabled (its disabled from form load)
1)type Blackcomb into the textbox and this will display BlackcombForm when button is clicked
2) type in XP into the textbox and it will load XPForm when button is clicked
3) type in Chicago into the textbox and it will load ChicagoForm when button is clicked
how would you do this?
In the end we're all just the same

in click of button write this code
textBox1.Text += "Form";
in event of textbox TextChanged write this code
if (textBox1.Text == "")
{
button1.Enabled = false;
}
else
{
button1.Enabled = true;
}

assuming that all your forms have been declared in a namespace called "WindowsApplication" you could do something like this:
In the click event handler of the button:
((Form)System.Reflection.Assembly.GetExecutingAssembly().CreateInstance("WindowsApplication." + textBox1.Text + "Form")).ShowDialog();
In the TextChanged event handler of the textbox:
button1.enabled =
textBox1.Text == "Blackcomb" || textBox1.Text == "XP" || textBox1.Text == "Chicago";

I think a nice solution could be done using a bit of Reflection...
<br />
<br />
string inputFormName = this.textBox1.Text;<br />
string CurrentFormAssemblyQualifiedName = this.GetType().AssemblyQualifiedName;<br />
<br />
string TargetFormAssemblyQualifiedName = CurrentFormAssemblyQualifiedName.Replace ( this.Name, inputFormName );<br />
<br />
System.Type formType = System.Type.GetType ( TargetFormAssemblyQualifiedName );<br />
<br />
if ( formType != null )<br />
{<br />
System.Windows.Forms.Form frm = ( System.Windows.Forms.Form )Activator.CreateInstance ( formType );<br />
frm.Show (); <br />
}<br />
<br />
This Example is working in my PC, because I have tested... It is based in the fact that both forms are in the Same project and folder ( means Exactly Namespace, and the TextBox has exactly the name of the Form... so you'll have to play a bit with it... )
Good Luck

Hi,
I am working on a website, in which i need to call a stored procedure to
update some fields of the database at regular intervals, say after every 30 days.
I am using Timers to call the stored procedure after the specified interval.
But i am in a fix as to where to place this code, so that it automatically gets executed on the server.
Or is there any other procedure i can follow to accomplish this task?
Thanks

if you're using SQL Server, why not just set it up on the server as a recurring job that runs every 30 days? 30 days is a LONG time to wait for an app to run for testing purposes. And even though you could probably simulate it another way, it's still not the same as waiting for it to actually run unattended.

I tried to use job scheduling, but noticed that the time period needs to be set, whereas, in my website, i might need to change the time interval... its could change to 40days or any other time interval.
The main purpose is to implement caching.
The records in the database would expire after a certain time interval and new records would be inserted.
I need to execute a stored procedure that would update the database and set the records as expired after the specified time interval.
Is there any possiblity to set the time period through my C# code?
Is there any other alternative to timers ?

Hi All,
I need a bit of help with algorithms. What I need is a method which takes a string as an argument and returns an array containing every permutation of the letters making up the string.
For example, with the input of Dog, I'd expect to see back:
dog
god
gdo
dgo
... etc in the array.
If anyone can help with this, it'd be much appreciated - especially if you can explain how it does it!
TIA
Utini.

Search for permutations and combinations, I am sure there are at least one example on CP

I have done this in the past for a Scrabble solver. You can uncomment the line; //retval.Add(current); if you want to see all possible sequences for a scrabble type solution (i.e. solutions that don't use all of the letters). If your word contains duplicate letters, you will have to sort the returned array and take out the duplicate string results.
private List<string> GetAllSequences(string str)
{
List<string> retval = new List<string>();
if (str.Length > 0)
{
if (str.Length == 1)
{
retval.Add(str);
}
else
{
string current;
string theRest;
for (int i = 0; i < str.Length; i++)
{
current = str.Substring(i, 1);
theRest = str.Remove(i, 1);
foreach (string appender in GetAllSequences(theRest))
{
retval.Add(current + appender);
}
}
}
}
return retval;
}

Hi!
First, many thanks for the good answers one usually receives on this forum!
Now, I would like some hints how I can control the painting of a UserControl. Let's say I have a bunch of buttons and some labels in this control. Then, at some time, I update the label contents and the button colors. But when the actual painting is performed it is not done synchronized, i.e., the buttons (in my case) is drawn slightly before the labels. I don't like the look of that! I would prefer showing the redrawn control AFTER all of its child controls have been redrawn. Is this possible?
Thanks.
