Hi all,
I am doing my first setup project for the addin I wrote and can't solve following problem.
I want to deploy an addin for Visual studio. So I need to look in registry for the HKLM\SOFTWARE\Microsoft\VisualStudio\7.X\InstallDir (where 7.X is 7.0 or 7.1) and take it into MyPATH0 and MyPATH1 variables. For the installed version(s) I need to make TARGETDIR to MyPATH0\..\..\\Vc7\VCWizards.
I have no idea how to solve this. Setup wizard seems to have very simple logic, so how can I program in the wizard
"
1.TAKE REGISTRY KEY XX\7.0 into VAR
2. If success Make VAR+AAA to the TARGET DIR
3.Install
4.TAKE REGISTRY KEY XX\7.1 into VAR+AAA
5. If success Make VAR to the TARGET DIR
"
Thank you very much for your help,
Boni

Hi guys, I need help, DatagridTableStyle property AlternatingBackColor alternates ones per row (odd numbers), i need it the alternate every two rows, (ex: Blue, Blue, Red, Red, .....) any idea how to do this?

Make your own DataGridColumnStyle or just change an existing one:
<br />
public class AlternatingColumnStyle : DataGridTextBoxColumn <br />
{<br />
protected override void Paint(Graphics g, Rectangle bounds, CurrencyManager source, int rowNum, Brush backBrush, Brush foreBrush, bool alignToRight)<br />
{ <br />
int i = rowNum % 4;<br />
Color c = Color.Blue;<br />
if (i > 1)<br />
c = Color.Red; <br />
base.Paint(g, bounds, source, rowNum, new SolidBrush(c), foreBrush, alignToRight);<br />
}<br />
}<br />

is there is any method to return web services values not from the net and web sites only but return it also from win apps on the web or the network or windows application that is connected to the net

Web services run in the IIS process and can only be executed within this process. What you're looking to do is called Remoting but it does not use Web Services.

Hey
I am Working on a Server/Client application in Asynchronous mode. I am using simple Socket when Asynchronous dont simes to be suported by TcpClient och TcpListener.
I am using Serializable on some objects(in a DLL file) to be abled to send this objects easy between the Server and Client, by this i dont want to work with a byte buffer, insted i want somthing like this.
<br />
stream = socket.GetStream(); <br />
formatter.Serialize(stream,user);<br />
There i easely can get the objects(if there is any in the stream. Tha abow code is not with a regular socket but a TcpClient.
Right now my Program looks like this
<br />
private void SetupRecieveCallback(Socket server)<br />
{<br />
try<br />
{<br />
if(server != null)<br />
{<br />
AsyncCallback recieveData = new AsyncCallback(OnRecievedData);<br />
<br />
<br />
}<br />
}<br />
catch(Exception ex)<br />
{ MessageBox.Show("Error in ForumClient - Connection - SetupRecieveCallback : " + ex.Message);<br />
}<br />
}<br />
<br />
<br />
public void OnRecievedData(IAsyncResult ar)<br />
{<br />
Socket server = (Socket)ar.AsyncState;<br />
try<br />
{<br />
int nbyte<br />
}<br />
catch(Exception ex)<br />
{<br />
MessageBox.Show("Error in ForumClient - Connection - OnRecievedData : " + ex.Message);<br />
}<br />
}<br />
How do i get the stream from the socket? and how do i implement it in my program ?

Have manage to get a stream no by using NetStream! ofcource =)
Now i have another question!
In the SetupRecieveCallback i am using server.BeginReceive(m_byBuffer,0,m_byBuffer.Length,SocketFlags.None,recieveData, server);
This will trigger so that OnRecievedData is thown if someone is sending data, but if i dont whant to use this buffert and insted use this
ForumPack.command user = (ForumPack.command)formatter.Deserialize(stream);
is there any way to do the same thing but with this stream? or do i have to use the buffert(and set the size) and then translate the byte in to the object?
BestRegards
SnowJim

I've a windows form, on which a picturebox is placed. I've loaded images into the picturebox. I've implemented the Zoom In and Zoom out functinality. Now my problem is when I zoom in, the picturebox is not spreading equally in the form. I mean the distance between picturebox and the container form should be equal, on four sides, as I zoom in and out ( the picturebox should be exactly centered). How can I achive this? Any help?
Here is the piece of code for Zoom In and Out
For Zooming In :
pictureBox1.Top= (int)(pictureBox1.Top - (pictureBox1.Height * 0.025));
pictureBox1.Left = (int)(pictureBox1.Left - (pictureBox1.Width * 0.025));
pictureBox1.Height = (int)(pictureBox1.Height + (pictureBox1.Height* 0.05));
pictureBox1.Width = (int)(pictureBox1.Width + (pictureBox1.Width * 0.05));
For Zooming Out :
pictureBox1.Top = (int)(pictureBox1.Top + (pictureBox1.Height * 0.025));
pictureBox1.Left = (int)(pictureBox1.Left + (pictureBox1.Width * 0.025));
pictureBox1.Height = (int)(pictureBox1.Height - (pictureBox1.Height* 0.05));
pictureBox1.Width = (int)(pictureBox1.Width - (pictureBox1.Width * 0.05));
Stay cool

I bet you can do a lot better than this with some custom drawing code. 
To answer your question about centering... the standard way of center goes like this:
int newX = (form.Width - picBox.Width) / 2;
int newY = (form.Height - picBox.Height) / 2;

Please explain what "down side" means. I don't exactly understand the problem.

Hi,
Yeah down side means that my image is scrolled bottom side of the screen.The whole scenerio is that whenever i draw a Rectangle on that image,vertical scrollbar is gone slightly down and due to that whole image gone down or say bottom side.
this is main problem.

Hello,
I am using a datagrid and l have update and delete, based on what the user clicked on.
Double click - display a form and with the details of the row what was double clicked to be able to update the customer.
Single click - click once on the row and then press a button to delete this customer.
My problem is, when l have these 2 events, it always goes into the single click event, wheather l double click the grid or single click the grid.
The code that l have to be able to update and delete works fine. But l can't do my update as the double click will always execute the single click event and not go into the double click. I have tried using mouse down event but that does not work either.
Is there way round this problem.
Many thanks in advance,
Steve

I have a checkbox that if checked, textBox1 gets enabled (texBox1.Enable=true) if uncheck it textBox1 gets disable.
I did this using another textBox to store the state and then compare. Is there an simple way to do this?
appreciate any help
|
|
|
|
|
Yes. The simple way is not to have the other textbox that stores the state. Since the checkbox control has a Checked property, what would you be storing in that other textbox? Let's see the code.

It's this simple:
void CheckBox1_CheckedChanged()
{
txtBox1.Enabled = CheckBox1.Checked;
}Check the event name, but it's something like that.

Its because i'm making a list control from scratch (a REAL list control, extends nothing more then System.Windows.Forms.Control)...and i'm looking for info to tell me what iterfaces my collection should implement...what should i extend...(i extended collectionbase, but some of the controls i seen just implement interfaces).
I already made a collection that works with designer, but i have no idea if its a good collection and i want the control to have a good foundation.
p.s. know of any other opensource truely custom(not extending any list control), besides glacialList?
