Put 2 labels on the statusstrip and set the "Spring" property of the left one to "true". That will push the one on the right out to the end of the strip.

You can also do this with a single label. Set 'Spring = true' and 'TextAlign = MiddleRight'.

Icon in MainMenu (IE style)

I was wondering if it is possible to have an icon or imagem (animated gif) on the right of the MainMenu, under the control box. Like IE has, or FireFox, or Explorer. I have searched everywhere on a way to do this without any luck.

MainMenu does not support having an image displayed on it. Since MainMenu is not a control, there is no way to custom render the image in an OnPaint override either (there is no OnPaint to override). The only option that I can think of is to PInvoke into whatever API is used by IE/Explorer to get that image on the menu. I have no clue what Win32 function provides that functionality.

Custom SNMP Agent development

Hi im new to SNMP and developing SNMP applications. I want to code up a custom agent that will run on a projector that is on my network. I was hoping
I could get some guidance as to how to go about this e.g.

How do I deploy it onto the projector?

whether it is possible to use the C# API, if so what class libraries?

if it would be better using something off the shelf to develop it?

Do I need to know about the low level API of the projector?

Any help on this would be much appreciated.

Tiff Image -> Searchable PDF [modified]

We have got several scanned documents(Tiff) in CDs, around 10GB of data. We are looking for a way to make them searchable PDF for easy accessibility.

We are using PDF creator to convert Tiff to PDF also we have built custom module on top of OCR engine which saves text from page by page in Xml.

So, How can I create Searchable PDF out of PDF Image and OCRed text in xml??

We are not looking for high end server side solutions, it would be nice if we can develop our own app or use opensource software.

MaulikCE

Hi Maulik,

You can use some OCR like Terrasact from Google or some Paid ones and convert the tiff to text. store the text in an Lucene index using lucence.net and then create a search interface for the lucene index.

let me know if you need any paid consultation for this solution.

My company can provide you the same.

Thanks,

I must print an html doc from a web service to a printer installed on the same machine as the web service.
I've tried instantiating a webbrowser object from my class but have threading model problems (cant do it!)

Can anyone shed ideas on how to successfully either :
a. print html from a web service
b. make a web browser object useable in a web service? (STAThread attribute seems to get ignored)

thanks!

hi all,
firstly:
>i defined a textbox1 on form1 passed on form2 and created form2 like this:
Form2 mehmet = new Form2(textBox1.Text);
mehmet.show();
>and form2's contructor :
public Form2(string s)
{
InitializeComponent();
lblUserName.Text = s;
lblLoginTime.Text = Convert.ToDateTime(DateTime.Now.TimeOfDay.ToString()).ToString("HH:mm:ss");
}
till now everything is fine Wink | ;)

what if i want to use that 'text' in another function or class ?
do i have to assign them to different variables in constructor first ???
and what if i have to pass not just one value but many values between forms ???
> is there a more sophisticated way ? or this is the method everyone uses ?

secondly: i defined that textbox1 (on form1) as public and in form2 defined something like this :

Form1 x = new Form1();
lblUserName.Text = x.textBox1.Text; > gives nothing ;(

lblUserName.Text is an empty string ??? cant i get the string value of textbox1 from form1 to form2 by setting it to public ???
where am i doing wrong ???
thanks in advance,
bye.

you must define it "Public Static" in form1 then u can use it without new form.

Then you see to it that the value gets there. There is nothing magical going on, the values are where you put them.

Mehmet Fatih Akbulut wrote:

Then you use more than one parameter or put the values together in a class or struct and pass that along.

You are creating a completely new instance of Form1. That instance will not have the data that you put in the instance of Form1 that already exists. To access the data in the existing instance, you need a reference to it.

how can i do this ?
would you please explain a bit more ?
or give a simple example ¿

You can send the reference along when you create the form:

Form2 mehmet = new Form2(this);

And recieve it in the constructor:

public Form2(Form1 form1)

Hi
Consider a RichTextBox with same data in it. Now when a user presses Ctrl key and Scrolls using the mouse the data present in the RichTextBox Zooms In/Out.

I want to disable the zooming of text in RichTextBox. I tried the following code and it worked on my machine but didnt work on other developers machine (not sure why).

private void RichTextBox_MouseWheel(object sender, MouseEventArgs e)
{
base.ZoomFactor = 1.0f;
}

How can i disable Text Zoom In/Out? Is there a property in RichTextBox which i am missing? Please let me know.

Thanks in advance

Writing thousands of images to disk

25-May-06 2:25

Hello, i am trying to write an application that saves about 11,520 images a minute a windows disk. The image size varies round the 8 to 20 kb. The application needs to run 24 / 7. At the moment i have a windows XP server service pack 2 and if i run the application after a 5 / 10 min the server crashes as the memory goes up and up. The commit charge rises all the time. I dont think i have a memory leak in the program but maybe the application is stressing the OS. Any raccomandations? any tuning i can do to the system. The application is written in c# .net v 2.0

Any help would be great as i have been banging my head on a wall now for some time

Thank in advance to any one that will take the time to read this

11520 a minute equates to 192 a second, sounds like alot of disk IO but maybe im wrong!

Are you sure you are disposing of objects correctly? Anything which implements IDisposable should have the Dispose() method called when you are done using it. If I remember correctly Image is IDisposable - could this be it?
