Re: find if word doc is already open (c# win app)

I posted this function before but modified it for your case. Not sure if this will help the finction checks if Microsoft Word program is running and if it is, the function returns true if not, it returns false. You can put this function in a function of a Timer class

//***************************************
//This is just an example of
//executing the function

if (MicrosoftWordIsRunning ()== true)
{
label1.Text = "Microsoft Word is RUNNING!";
}
else label1.Text = "Word is NOT running.";
//*****************************************

that executes the MicrosoftWordIsRunning function at a specified interval - therefore checking every let's say 1000 milliseconds (1 second).

Let me know if you have any questions.

Make sure you include System.Diagnostics:

using System.Diagnostics;//put at the beginning

//put function in class
private bool MicrosoftWordIsRunning()
{
Process[] myProcess = Process.GetProcesses();
int i = 0;

try
{
while (myProcess[i] != null)
{
if (myProcess[i].ProcessName.ToUpper() == "WINWORD")
{
int i2 = 0;

try
{
while (myProcess[i2] != null)
{
myProcess[i2].Close();
i2 += 1;
}
}
catch { }

return true;
}
i += 1;
}
}
catch { }

int i3 = 0;

try
{
while (myProcess[i3] != null)
{
myProcess[i3].Close();
i3 += 1;
}
}
catch { }

return false;
}

LinkLabels array

I have a dictionary array with 7 elements: Dictionary<int, string> catDict
and from this array I create linklabels private LinkLabel[] categoriesLinks = new LinkLabel[15]
I do it so:

foreach (KeyValuePair<int, string> kvp in catDict)<br />
        {<br />
            <br />
            this.categoriesLinks[kvp.Key] = new LinkLabel();<br />
            this.categoriesLinks[kvp.Key].Location = new System.Drawing.Point(42, 39 + i * 17);<br />
            this.categoriesLinks[kvp.Key].Name = kvp.Value;<br />
            this.categoriesLinks[kvp.Key].Size = new System.Drawing.Size(115, 13);<br />
            this.categoriesLinks[kvp.Key].TabIndex = 1;<br />
            this.categoriesLinks[kvp.Key].TabStop = true;<br />
            this.categoriesLinks[kvp.Key].Text = kvp.Value;<br />
            this.categoriesLinks[kvp.Key].Click += new EventHandler(catClick);<br />
            <br />
            this.Controls.Add(this.categoriesLinks[kvp.Key]);<br />
            i++;<br />
        }

And also i have a event for click:

private void catClick(object obj, EventArgs ea)<br />
{<br />
}

How can I in catClick event detect which linkLabel was clicked? Actually I want to know what kvp.Key has this linkLabel.

you can use the obj to find out the linklabel name. just cast the obj to a linklabel.

<br />
LinkLabel l = (LinkLabel)obj;<br />
MessageBox.Show(l.name);<br />
<br />

Minimize problem

Cool^ASL27-Dec-05 2:19

27-Dec-05 2:19

Hi all,
i have created an app which displays a non-rectangular window (i.e the FormBorderStyle is set to none)
I added a button to minimize the window using:
this.WindowState = FormWindowState.Minimized;

This minimizes the window properly to the taskbar (i dont mean the system tray)
When i again click on the window in the task bar, the window pops us and is back as normal. But when i take the mouse over the window it disappears and doesnt come back.

Can anyone tell me where i am going wrong ????? Confused | :confused:

It seems right make sure the form properties in the InitializeComponent() function are all correct. These are mine and they work fine:

private void InitializeComponent()
{
//Code for Button, etc. initialization here

//
// Form1
//
this.AcceptButton = this.button1;
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(433, 260);
this.Controls.Add(this.textBox1);
this.Controls.Add(this.button1);
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.KeyPreview = true;
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
this.PerformLayout();

}

// Here is the code in the form class

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{

this.WindowState = FormWindowState.Minimized;
}
}

//Let me know if it doesn't work still

Hi Peshkunta,
Thanks for the reply.
I tried adding your code to mine..
But the problem is that there are no properties of the form named as either AutoScaleDimensions or AutoScaleMode:

....<br />
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);<br />
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;<br />
....

I searched the MSDN too, but no such property is listed there. At the most, i was able to find AutoScaleBaseSize and ClientSize.

Here's my code. Can you please see, if there is anything which i need to add.

private void InitializeComponent()
{
	this.textBox1 = new System.Windows.Forms.TextBox();
	this.richTextBox1 = new System.Windows.Forms.RichTextBox();
	this.SuspendLayout();
	// 
	// textBox1
	// 
	this.textBox1.BackColor = System.Drawing.Color.White;
	this.textBox1.BorderStyle = System.Windows.Forms.BorderStyle.None;
	this.textBox1.ForeColor = System.Drawing.Color.Black;
	this.textBox1.Location = new System.Drawing.Point(16, 168);
	this.textBox1.Multiline = true;
	this.textBox1.Name = "textBox1";
	this.textBox1.Size = new System.Drawing.Size(269, 16);
	this.textBox1.TabIndex = 1;
	this.textBox1.Text = "";
	// 
	// richTextBox1
	// 
	this.richTextBox1.BorderStyle = System.Windows.Forms.BorderStyle.None;
	this.richTextBox1.ForeColor = System.Drawing.Color.FromArgb(((System.Byte)(102)), ((System.Byte)(102)), ((System.Byte)(153)));
	this.richTextBox1.Location = new System.Drawing.Point(16, 32);
	this.richTextBox1.Name = "richTextBox1";
	this.richTextBox1.ReadOnly = true;
	this.richTextBox1.ScrollBars = System.Windows.Forms.RichTextBoxScrollBars.ForcedHorizontal;
	this.richTextBox1.Size = new System.Drawing.Size(269, 128);
	this.richTextBox1.TabIndex = 2;
	this.richTextBox1.Text = "";
	// 
	// Form1
	// 
	this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
	this.ClientSize = new System.Drawing.Size(433, 260);

	this.BackColor = System.Drawing.Color.Lime;
	this.ClientSize = new System.Drawing.Size(312, 208);
	this.Controls.Add(this.richTextBox1);
	this.Controls.Add(this.textBox1);
	this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
	this.MaximizeBox = false;
	this.MinimizeBox = false;
	this.Name = "Form1";
	this.Text = "Form1";
	this.TransparencyKey = System.Drawing.Color.Lime;
	this.KeyPreview = true;

	this.Resize += new System.EventHandler(this.Form1_Resize);
	this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseDown);
	this.Load += new System.EventHandler(this.Form1_Load);
	this.MouseUp += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseUp);
	this.Paint += new System.Windows.Forms.PaintEventHandler(this.Form1_Paint);
	this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseMove);

	this.ResumeLayout(false);

}

Please see, if i am missing anything !!!!
Thanks.

I think the problem is in the event handler functions Form1_Resize, and the others:

this.Resize += new System.EventHandler(this.Form1_Resize);
this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseDown);
this.Load += new System.EventHandler(this.Form1_Load);
this.MouseUp += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseUp);
this.Paint += new System.Windows.Forms.PaintEventHandler(this.Form1_Paint);this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseMove);

If you can, I would like to see the code in those. I was wondering what method/way you use to minimize the form/dialog since your dialog has no border. Are you using a button, or just a hit-test location on the form to click? If you want to have your own custom minimize button, one easy way to do it is to create a normal button and set it to Flat style, with no text and your image in the button that can change when you press for button being pressed, etc. Make sure the Flat button BorderSize is set to 0 otherwise there will be a border there. And make sure the MouseDownBackColor and MouseOverBackColor are set to Transperent.

Hi Peshkunta...
Thanks...
That was a real help.
There is some problem with my code.
I had actually used an image which would minimze the window when clicked.

i had always wanted to create a custom button.
Hey, but i am not able to find any property of the button called as BorderSize, MouseDownBackColor and MouseOverBackColor.. Are you talking about VC or C#..??
Maybe i am missing something.. can you please figure it out.

Thanks in advance.
Amrit.

I'm using C# - Visual Studio 8 (2005).

In the button Properties window look for FlatStyle property. Just above it is a propery called FlatAppearence and in front of the text is a + if you click on it it will expand and show you BorderSize, etc.

I'll check it out... thanks for the help.
Sorry for disturbing you for so long.

Not a problem at all - glad to help.

If you don't have the option to do the transparent color in the flat button, alternatively you can use PictureBox or Panel control (I would go with PictureBox) for the same effect. I use PNG files for transparency - if it's transparent in the PNG file it comes out transparent in the button, imagebox, panel etc. Let me know if you find the flat style button transparency property and if you have any other question. You can also make a custom form/dialogbox. So it doesn't have to have the sharp edges - you can have a circle dialog box. If you don't know how to do it and need that, let me know.

PS.

Look and see if you have these properties:

this.button1.FlatAppearance.BorderSize = 0;
this.button1.FlatAppearance.MouseDownBackColor = System.Drawing.Color.Transparent;
this.button1.FlatAppearance.MouseOverBackColor = System.Drawing.Color.Transparent;
this.button1.FlatStyle = System.Windows.Forms.FlatStyle.Flat;

Cool^ASL27-Dec-05 20:58

27-Dec-05 20:58

Yes..
thats exactly what i am doing.. i have made up the window using some images (using GDI+).
That minimize problem was occuring because of the code that i had written for detecting the click on that image used for closing the window. I havent worked down to the root of the problem yet.. i'll do it once i get out of my office.

I was actually inspired to make such a custom window when i used Google Talk.
Its cool... i have made seperate images for the titlebar, the body and the buttons. I had some problem while customizing the button, so i left it for the meanwhile. So, i use GraphicsPath to bring them all together and compose the window.
But i have a problem in store for me... how do i go about writing code to help the user in expanding the window. I mean how to detect when the mouse has been placed on the border of the window and how to expand the window.... because if i do so, the images will be distorted.
Can you tell me, how to go about doing it. Or simply put, what approach do you use... (something which i can implement in Visual Studio 7)

Thanks !!!!

That would be more challenging. Normally the skins in a custom app don't change - the app doesn't visually resize. What you could do in that case is have 4 pictureboxes and dock them in each corner. When the app resizes so will the pictureboxes automatically. What you would have to do in that case is make sure the picture of the border/frame is very high resolution/large picture - large enough so that when it explands it won't get pixelated.

Hmmm.. that would be nice.. i'll give it a try.
Well, you are right that such windows are rarely expandable..
Hey, but look at Google talk window... it is allowed to expand the window there. But very cleverly, they have the background of the window as white... must be some nice trick up their sleeves.

Anyway, i'll give it a try and let you know.
Thanks for all the cool advice.

There is a way to make custom controls with custom properties that is much cleaner than this, but it requires more code.

Google talk doesn't seem hard to make, with exception of the semitransparent shadow if this shadow is not caused by the operating system.
D'Oh! | :doh:

After reading your reply and sending my reply, i made a different form and created a button to help it minimize and also added code to help it move around.
But this one is working fine... OMG | :OMG:

Seems that there is something wrong with my code. Frown | :(

Hi
This question is related to printing in .NET winform application, I am working on a wizard kind of application (in.NET using C# language) where in user will be guided through a set of win forms that collects user response for a series of questions (and stores/saves as a file in a srialized format).
I am at a stage where in i have to implement the "print and print preview" functionality for this application, Could you please suggest what is the best method to accomplish this task?
Tricky bit for me is - wizard/questionnaire contains (at some stage) a list view that will have entries which opens into child windows where the detailed information is displayed.(for eg, if the wizard collects information about a student, at some stage it has to provide in a list view, number of subjects he/she enroled into and upon clicking it opens a child window with details of subject/enrolment).

Your help in any form is greately appreciated!! Sorry if i haven't explained the problem clearly!!!

Thanks
Sr
