Not easily. The only langauge in vs.net that will produce native code directly is unmanaged(normal) c++. There are a few 3rd party tools that will compile the IL produced by the other .net langauges into an executable but they're all afaik expensive.

It is theoretically possible but what possible application would there be for doing such a thing? Not only would your application have to be "compiled" again but all subsequent assemblies have to be sucked in. You'd either end up with a very large executible or a complete duplication of the .Net Framework in a C runtime format.
You could ask the same thing about VB 6 to C and note no one does this. The possible advantages of changing runtime formats is way outweighed by the complexity of doing so.

Hi
I'm trying to work out how to nest datagrids. The parent child way that is supported by default is a little bit limited for my needs.
Here is an image of what i'm trying to do, I quickly photoshopped this together so theres no drill down buttons and lines showing the hierarchy.
Example
I also need to add things like combo boxes to certain columns (which I think I can do) I'm fairly new to windows forms, so I don't know by way around very well. I can find tons of stuff for ASP.NET but thats not helpful for my windows app. i'm trying to do this in C# using .NET 1.1
The data that goes into this datagrid comes from a join between two tables. Its a shame you can't write windows forms in HTML and CSS and it generates a windows interface from that

Hi Everyone,
Does anyone know if there exists Assemblies in .Net 1.1 with which I can do load balancing on a server app that accepts TCP connections?
Thanks and Cheers!
Phi?
|
|
|
|
|
As far as I know, load balancing is not done at the software application level. If NICs are load balanced they should automatically balance the traffice between the merged NICs. When you send traffic using .NET the load balancing should be auto handled.
|
|
|
|
|
Raheem is correct. Applications are not expected, nor recommended, to do their own load balancing. This is best left up to the server/network level. Your application must be written with load balancing in mind, though.

Hi,
When the treeView control's nodes are right-clicked,
the selectedNode of the treeView won't be changed unless
it is a left-click mouse event.
My problem is that I associated context menu to the tree
nodes, so user just right click the node to use the context
menu, however the selectedNode isn't the node that the context menu
is launched.
So how can I set the selectedNode to the node that is right-clicked ?
Thanks
|
|
|
|
|
Hi!
You could catch the MouseUp event and then use TreeView.GetNodeAt() to get the node the mouse is over currently.

mav

 Excel enables the creation of user-defined functions that can be used in Excel formulas. So I use these code to create a COM introp.
-------------------------------------------------
using System;
using System.Runtime.InteropServices;
using Microsoft.Win32;
namespace AutomationAddin {
[ClassInterface(ClassInterfaceType.AutoDual)]
public class MyFunctions {
public MyFunctions() {
}
public double MultiplyNTimes(double number1,
double number2, double timesToMultiply) {
double result = number1;
for (double i = 0; i < timesToMultiply; i++) {
result = result * number2;
}
return result;
}
[ComRegisterFunctionAttribute]
public static void RegisterFunction(Type type) {
Registry.ClassesRoot.CreateSubKey(
GetSubKeyName(type));
}
[ComUnregisterFunctionAttribute]
public static void UnregisterFunction(Type type) {
Registry.ClassesRoot.DeleteSubKey(
GetSubKeyName(type), false);
}
private static string GetSubKeyName(Type type) {
System.Text.StringBuilder s =
new System.Text.StringBuilder();
s.Append(@"CLSID\{");
s.Append(type.GUID.ToString().ToUpper());
s.Append(@"}\Programmable");
return s.ToString();
}
}
}
-----------------------------------------------------
And set project build property,checked output item,register COM interop.
Building the project,that's success.
Launch Excel and choose Add-Ins from the Tools menu to display the Add-Ins dialog. In the Add-Ins dialog, click the Automation button. But I can't find the class I created by looking for AutomationAddin.MyFunctions in the list of automation servers.
What's wrong? Please help me !Thanks,by the way,My development tool is VS2005 ,Office 2003 (sp2)simply chinese.

Hi guys,
I want to ask a question about diabling a control.
I have to select boxes, regions and areas. And a text box that represents a unique ID.
Now I only want the user to search either by location, or by unique ID. So if the user selects a region, all the areas for that regions are loaded in the area select control. Then, in the same process, it should make the textbox ReadOnly (so that no data can be entered), which works fine. But my problems comes is, if the user starts to type in a unique ID, then it should disable the 2 select boxes. If the textbox is cleared, then the 2 select boxes are enabled again.
I'm not sure if there is an event that checks for this? I think there is an event for the textbox something like text changed, but this doesn't work when I start typing in text, probably because it doesn't make a trip to the server. Is my only option for this via Javascript? Or can I do this on the server? I'm using C#.
Regards.

Unfortunately for right now, if you're wanting to do real time text checks on the web page then some type of Client side script (such as Javascript) is your only option. The only way for the server to manage this is for the page to postback to the server every time the user presses a key in the textbox, which would keep them from typing more than say.. 3 words per minute.

That's exactly why. ASP.NET is a server-side only technology designed to generate HTML for browsers. It's can't interact with the client in real-time.

Yep. JavaScript is your only option if you want cross-browser compatibility.

hi,

AMC.Size= new System.Drawing.Size(this.Size.Width,this.Size.Height-40);
The problem is with AMC.Lication
one problem is when i am using the user control,if its (AMCs) Location.X is set to Location.X of its parent (user control) + some value whjich doesnt make sence as i have set it to this.Location.X only
what more is bothering is
i am creating 3 instances of this user control in my form and by calling the statement
AMC.Location=new System.Drawing.Point(this.Location.X,this.Location.Y+26);it is setting Locatin of each of the AMC to the locatin if first instance, the prob. is not with ActiveX AMC because i have tried it with a Label as well an the probleaim is still the same

Hi!
You'll have to override WndProc for this and scan the messages for WM_SCROLL and related messages.

Or....Not. We're not in the business of answering homework problems here. If you have a question once you've started, feel free to ask...but you need to show some work before we're going to start helping you.
Picture a huge catholic cathedral. In it there's many people, including a gregorian monk choir. You know, those who sing beautifully. Then they start singing, in latin, as they always do: "Ad hominem..."

What is the best way to handle an invalid input?
void DrawComplexNumber1(Graphics g)
{
Pen p = c_xy.GetNextPen();
p.DashStyle = DashStyle.Dot;
c_xy.SetOrigin(xIndent + graphRect.Width/2, yIndent + graphRect.Y/2);
cmplxValue1.Real = Convert.ToDouble(textComplex_1Real.Text);
//wHAT IF INVALID? need CODE
cmplxValue1.Imaginary = Convert.ToDouble(textComplex_1Imaginary.Text);
//WHAT IF INVALID? need CODE
g.DrawLine(p, 250, 250, (float)(250 + (xIndent * cmplxValue1.Real)), (float)(250 - (yIndent * cmplxValue1.Imaginary)));
}
thanks a lot....

Hi all,
I'm trying to implement a view of a grid simliar to a view that you would see on an AS400. The same data is display for all views, but the columns (left to right) change based on the view selected.
grid col 1,2,3,4,5,6,7,8,9,10
user changes to view based on #4
4,3,2,1,5,6,7,8,9,10
user changes to view based on #8
8,9,10,1,2,3,4,5,6,7
I hope this defines it accurately. Same data, same columns, same table, same dataset, just juggle the columns around based on a user defined criteria.
Any help at all would be greatly appreciated!
BTW, I'm new to C# so URL's, references to help text, etc. is greatly appreciated as well .
TIA

I am using Color.FromArgb to draw a transparent image pixel by pixel. It is pretty slow. Is there a faster way to render a transparent image?
|
|
|
|
|
|
There is no transparent setting in drawimage func. My major problem is I have to change the degree of transparency frequently, so I cannot render the image once and paste the same image with drawimage.

I want to draw a rectangle while moving the mouse. But the event handlers below would preserve all the intermediate rectangles in the window. How to erase the intermediate rectangles and only show the last rectangle?
Thanks.
private void Form1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
firstpoint = new Point(e.X,e.Y);
}
private void Form1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
Graphics g = this.CreateGraphics();
Pen dotPen = new Pen(Color.Black, 1);dotPen.DashStyle=DashStyle.Dot;
g.DrawRectangle(dotPen,firstpoint.X,firstpoint.Y,e.X-firstpoint.X,e.Y-firstpoint.Y);
}
private void Form1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
secondpoint=new Point(e.X,e.Y);
Graphics g = this.CreateGraphics();
Pen dotPen = new Pen(Color.Black, 1);dotPen.DashStyle=DashStyle.Dot;
g.DrawRectangle(dotPen,firstpoint.X,firstpoint.Y,e.X-firstpoint.X,e.Y-firstpoint.Y);
}

I think you should draw your rectangle in the Form's Paint event
As per my knowledge using the CreateGraphics() draws a drawing permanently
