Ok..Is there a way on how to solve that problem? I'm thinking of declaring an array that is large enough for me to store those names.

I hope you aren't asking for a way to declare an array of a given size..
int[] b = new int[vehicleCountInt + 1]; is one such declaration, but probably 1 too big (why are you adding one?)

If you are asking how to assign to an array which is a function parameter, well, ref is used for exactly that purpose, but out may be sufficient. But this "problem" is as trivial as the first.

Well I'm referring to how will I solve the problem about the uncertainty of the array's size. I've declared 5 text files with 30 data inside. Now what my groupmate did was create a text file and put there the total number of data inside the text files, and that's the vehicleCount.

Now what I'm thinking is declare an array that has a definite size (say 50) which will hold the data inside the text file(the 30 predefined data and the user's additional inputs). Will this solve the problem about the IndexOutOfRange exception?

Declaring an array to be intentionally too big is not really nice
You could make it a List or read the file all at once and then split on newlines

Your right...It didn't solve the problem..I'm sticking to the original code that we created (having a text file that acts like a counter).

Display the Properties tab in VS when focus is on the GridView, and click the Events button. Scroll to the 'Click' event and select the appropriate event; the designer will create stub code and navigate to the function so you can add your code.

You can buy tools to do this, which actually do patch the binary.

You can also use winzip self extractor to deploy just the files needed to update an install.

Further to Christian's answer, a patch should only include changed files. If you can identify which files are changed, then the problem of building a patch is solved. If you are thinking of patching a single binary then there a potential problems. It is better to ship each component file in full.

Maybe NetDasm - A tool to disassemble and patch .NET assemblies[^] from here on CP will help. If that one does not suit search the articles for patch, there are several likely articles.

I use it like this :

In Program.cs, you can see :
Application.Run(new Form1());

So, I create a new form, call it SplashScreen.
In that form I create a timer, for example 3s.
In event splashScreen_Load, I start the timer.
After 3s, I get an event timer_Tick.
In that event, I close the form.

So, change the line in Program.cs to :
Application.Run(new SplashScreen()); // will show for 3s, then closed
Application.Run(new Form1()); // after that, Form1 will show.

First add a form and name it as splashForm and then on that form remove the border and place a picture box which contains a suitable image.
Include using system.thread;
now in the main form(Form1)

 public Form1()
        {
thread = new Thread(new ThreadStart(SplashForm));
            thread.Start();
        }


private void SplashForm()
        {
//This opens the splashForm which you have created
            SplashForm newSplashForm = new SplashForm();
            newSplashForm.ShowDialog();
            newSplashForm.Dispose();
        } 
private void Form1_Load(object sender, EventArgs e)
        {
            thread.Abort();
        }

I hope this helps you...

DataGridView: Using different fonts in single DataGridViewTextBoxCell

cuker11-Sep-09 23:28

I need to "highlight" (e.g. make it bold) one word in a whole string used as a value in a cell. Is it possible?
I am using DataGridView, DataGridViewRow and DataGridViewTextBoxCell classes in my application.
Here is the snippet of the code:

DataGridViewRow aNewRow = null;
foreach (MatchData aMatchData in aSeasonData)
{
    aNewRow = new DataGridViewRow();
    DataGridViewTextBoxCell aCell = new DataGridViewTextBoxCell();
    aCell.Value = aMatchData.Date;
    aNewRow.Cells.Add(aCell);

    aNewRow = new DataGridViewRow();
    DataGridViewTextBoxCell aCell = new DataGridViewTextBoxCell();
    aCell.Value = aMatchData.WhoPlaysWho;
    aNewRow.Cells.Add(aCell);

    aCell = new DataGridViewTextBoxCell();
    aCell.Value = aMatchData.Result;
    aNewRow.Cells.Add(aCell);

    this.myListOfMatchesGridView.Rows.Add(aNewRow);
}

where myListOfMatchesGridView is of type DataGridView.
And according to the result stored in aMatchData.Result (e.g. 2:1 or 4:2) I need to make the winner team (stored in WhoPlaysWho) bold e.g. if the match was Legends vs. AllStars and the result was 3:1 for Legends the displayed output in the specific cell should be Legends vs. AllStars.

Please, give me a hint how to achieve this. From all I read about DataGrids I know how to change the font for the whole cell but so far I was not able to get an information how to change the font only for one word in a whole string (and use different font for the rest of the string) i.e. how to use two (or more) different fonts in one single cell.

AFAIK, you can't make the text partially bold. You could go for owner-drawing[^], and draw the text manually.

Thanks for your answer, although not the one I expected Smile | :)

Meanwhile I got another idea - what about using a rich text box as a grid cell? Is there any possibility to make use of it?

Yes, it should be possible to use any .NET control[^] within that DataGrid Smile | :)

Hi

I think it will reset the first record of the dropdownlist, when ever you load or refresh the datagridview.

if i am correct.
you need to set the selected index of a dropdownlist in row binding event of the datagridview.

i can suggest...

or use text box along with dropdownlist.
or lable along with dropdownlist

so just show the dropdownlist box only at the click of a cell.
and after selection hide the ddl and show the lable

Hi,
Thanks for your reply. I am copying here the code..bcoz I have already bound the dropdownbox but when i am selecting value it's get blank.

private void GetAnalysisitem()
{

using (new SessionScope(FlushAction.Never))
l_Analysisitem = ANALYSISITEM.FindAll();

if (l_Analysisitem != null)
{
DataSet ds = new DataSet();
TAnalysisitem = CastleUtil.ConvToDataTable(l_Analysisitem);
TAnalysisitem.TableName = "ANALYSISITEM";
TAnalysisitem.AcceptChanges();
ds.Tables.Add(TAnalysisitem);

// attach the dropdown to the categories column
this.c1TrueDBGrid2.Columns["MATERIAL"].DropDown = this.c1TrueDBDropdown1;

// underlying datasource value is ID
this.c1TrueDBDropdown1.DataField = "ID";

// display value will be Name
this.c1TrueDBDropdown1.ListField = "NAME";

// tell the grid that we're translating values
this.c1TrueDBGrid2.Columns["MATERIAL"].ValueItems.Translate = true;

// now use the dropdown to perform the translation for us
// using a more readable format (i.e.,"Name")
this.c1TrueDBDropdown1.ValueTranslate = true;

aNALYSISITEMBindingSource.DataSource = l_Analysisitem;

c1TrueDBGrid2.SetDataBinding(ds, "ANALYSISITEM", true);

}

TAnalysisitem.RowChanged += new DataRowChangeEventHandler(TAnalysisitem_RowChanged);
TAnalysisitem.RowDeleted += new DataRowChangeEventHandler(TAnalysisitem_RowChanged);

}
