Hi,
I'm quite new to .NET framework, though I am quite experienced in C++.
I have this problem I can't seem to solve under .NET framework. I'm using VS2008, so the new syntax is used as well to describe it.
In short I wouldlike to pass a String object to a function that "fills" it with some calculated content, and then the string can be used by the callee with the new content. This can be done with simple passing by reference under "normal" C++, but not with .NET.
Something like this:
System::Void ParserCaller() {
String ^name1, ^name2;
FillThis(name1, name2);
System::Console::WriteLine("1) {0}, 2) {1}", name1, name2);
}
System::Void FillThis(String ^name1, String ^name2) {
name1 = "Anything calculated or retreived from some other source";
name2 = "Anything calculated or retreived from some other source again";
}
As you see returning both strings as return parameter is not possible.
Is there a way to obtain the above with .NET object handles?
Thansk in advance.

Managed String objects are immutable under .NET. You can't change an existing string, you can only return a new string. A StringBuilder object can do what you want though, since it's treated as an array of characters instead of a string. You can get the string equivilent out of the StringBuilder by calling it's ToString method.

Thanks a lot. I'm going to look for the StringBuilder object then.
/edit: I managed to get exactòy what I wanted with the StringBuilder object.
How annoying there's not a clear() method for it, BTW.
Is setting the string length to 0 the best method to clear it or there's a smarter way to do that?
Thanks again

Setting the length to 0 works just fine. If the length property is increased, any new characters added to the existing length are automatically initialized to 0, or Unicode NULL. This prevents the previous contents of the stringbuilder from being recovered and prevents the stringbuilder from being used to "capture" the previous contents of memory, closing a possible security hole.

Hello Everybody,
Hope all are doing well.
I have an application where I have to show data in a gridview.
I want that when user scroll the horizontal scrollbar first 3 columns should not be scrolled i.e. first 3 columns should always shown like we shown the header of the gridview to the user always at the time of vertical scrolling. Like this also I want a row in the bottom should always shown to the user(it could be the footer).Plz send me the sample if u have otherwise
tell me how to achieve this.
Thanks in Advance.
Happy Coding!!!!!!
A key to every Solution

Both the DataGridViewColumn and DataGridViewRow classes expose a Frozen property that does this. All you have to do is set the Frozen property of the columns you want not to scroll.
myDGV.Columns(0).Frozen = True

Hi All,
I want to generate a table and add the rows (it contains 2 TDs) dynamically and this table should be in just like div and this div should be present like a popup when I do right click on the link. This should be done using JSON like in each TD, we are displaying links dynamically and calling webservices by clicking on those links
Thanks

I assume you want the ASP.NET forum then ?
JSON just returns data, it's up to you to turn that into rows in your table.

Actually, we are generating dynamic controls instead static controls. So, i just want to generate the dynamic popup when we do right click on the link and popup should contain just like table and the rows will be increased depending on the data retrieved.
So, if you provide the logic for this scenario, its fine.
But, the answer you have given is not appropriate
Thanks

We are doing the UI part in JSON format. we got new feature for the next release. I have searched so many links, but I got only javascript with this requirement, not the json. So, I have posted here.
I am not saying that your answer is not correct, but I think that the answer, which he has given is not suitable to my question.
Thanks,
Visala

Oh, maybe it was just your wording that threw me into judgemental waters. You can't program with JSON, only with JavaScript, which will use your JSON data to manipulate DHTML elements to present tables, selects etc. Try looking for some resources on DHTML and JSON serialisation. I'm can't help more than that, 'cos I don't really know more.

I created table dynamically, but I am not getting the right click option even I use setcapture() and it is not displayed like a popup.
The function, which I have written to generate the table is as follows. If you find anything to do, please let me know
function createDynTable(row, col)
{
oContextMenu.innerHTML="";
//oContextObject=oTarget;
iMenuItems=0;
oContextMenu.setCapture();
// get the reference for the body
var mybody = document.getElementsByTagName("body")[0];
var mydiv = document.createElement("div");
// creates a <table> element and a <tbody> element
mytable = document.createElement("table");
mytablebody = document.createElement("tbody");
// creating all cells
for(var j = 0; j < row; j++) {
// creates a <tr> element
mycurrent_row = document.createElement("tr");
for(var i = 0; i < col; i++) {
// creates a <td> element
mycurrent_cell = document.createElement("td");
// add edit cell;
mycurrent_cell.ondblclick = function (evt) { editCell(this);};
// creates a text node
currenttext = document.createTextNode("cell is row "+j+", column "+i);
// appends the text node we created into the cell <td>
mycurrent_cell.appendChild(currenttext);
// appends the cell <td> into the row <tr>
mycurrent_row.appendChild(mycurrent_cell);
}
// appends the row <tr> into <tbody>
mytablebody.appendChild(mycurrent_row);
}
// appends <tbody> into <table>
mytable.appendChild(mytablebody);
mydiv.appendChild(mytable);
// appends <table> into <body>
mybody.appendChild(mytable);
// sets the border attribute of mytable to 2;
mytable.setAttribute("border", "2");
//return mytable;
oContextMenu.innerHTML=mytable;
iMenuItems++;
}
Thanks,

Actually, the answer is spot on. This is NOT the forum for this question. There is an ASP.NET and a web programming forum on this site. Either would have been a more appropriate choice. There are reasons that we don't just have one forum here on the site - it's so that people can find answers to problems in readily accessible locations without having to wade through questions about technology's they couldn't care less about.

I am using windows installer. I need to find where A product was installed and copy the packed dlls to the installed folder. So users are forbidden to change the install path.
My questions are:
1. How to invalid the “browser” button so that users cannot change the install path?
2. How can I run some code(e.g. call a dll) at the very beginning of installation? By over writting "Install" and "BeforeInstall" methods, it can only run after the dlls were copied to installed path!
thanks so much!
do it.

Looks like it's a Java control. Which means, you can't. Unless you create a java window and write tons of code to communicate between C# and the fake child window that is really a Java app.
