Re: Hide Form - C# Discussion Boards

29-Sep-05 23:29

Hi
I have an app, which main form at startup isn't shown. It is minimized, it is not shown in the taskbar and the app present itself via a systray icon. If u whant to see the Form, you click on the systray icon and I maximize the Form.

The problem is, that I get a small form bar in the lower left corner of the screen, when my app is minimized and I don't whant that, since I got my systray icon to remaximize it with.

How do I remove that annoying bar?

I tried setting the Opacity property and that actually worked. Great!

Here I need to point out, that the app is a Support app, which our support division can use when using Remote Desktop on our customers PCs.

I therefore tried using Remote Desktop and to my surprise the app whent invisible! OMG | :OMG:

I could not maximize it anymore. After some debugging I discovered that the Opacity property caused that!?! Confused | :confused:

So if any of you have a solution other than using the Opacity property I would greatly appreciate it.

TIA

Have you tried -
form.Size = new Size(0,0);
?

Try setting the FormBorderStyle property of the form to FormBorderStyle.None.

hmmm - that works when my app starts, but when I Maximize it and the Minimize it again, the Form bar reappears... Confused | :confused:

It just came to my mind that you could instead of minimizing the form and trying to hide the bar just make the whole form invisible (form.Visible = false;).

I tried that too Smile | :)

to no avail.

And I got it working using Hide(), except at startup. I tried to Hide() it in another thread like this:

public MainForm()
{
InitializeComponent();
Thread t = new Thread(new ThreadStart(HideFunc));
t.Start();
}//constructor

private void HideFunc()
{
Thread.Sleep(1);
this.Hide();
}

It works (even though the Form flickers before hiding). If I remove the Sleep(1) call the Form whont hide!?

Am I missing some fundamental programming issue here or what?

Hi all,

I am fairly new to C# and I was wondering if any of you can help me with Crystal...

I have a dialog box with a couple of controlls on it! I want to select a sales person, a starting date and an end date, send Crystal a little sql stmt based on the values I selected from the dialog, and draw my report!

Any help will be greatly appreciated!

Kind greetings Smile | :)

I have to say I officially hate Crystal, sorry. But I have to use it. I'll try to tell you what I have done, and hopefully this will get you started in the right direction.

First I created an XSD by clicking on the project in question --> Add New Item --> XML Schema. Open the schema in the designer and put in the fields and their data types for the data as you want to see it on the report. You can add elements and such by right-clicking in the schema window.

After you are done with that, right-click in the schema window and select Generate Dataset. If you were to click your "Show All Files" button on your project, you would notice that you now have a new .cs file underneath your xsd schema. This is known as a "strongly-typed dataset", if I'm not mistaken.

Now, Crystal is ready to accept your information. The next step is designing the Crystal report itself. Add New Item --> Crystal Report, and you get a report file .rpt. If you right-click in the Field Explorer (on the left hand side) [and probably this is available somewhere in the menu system], you need to find Add/Remove Database. You should see a list of potential data sources, and you should see your strongly-typed dataset here.

I won't walk you through designing a report [edit]although happy to give help if requested[/edit]...

Next step is displaying the report. Create a new blank Windows Form in your project, and drag a CrystalReportViewer component on to the form, and dock it using Fill. [BTW, You probably need to be referencing "CrystalDecisions.CrystalReports.Engine", "CrystalDecisions.ReportSource", "CrystalDecisions.Shared", and "CrystalDecisions.Windows.Forms" in your project]. If you don't see a CrystalReportViewer component anywhere in your toolbox, right-click your toolbox, choose add/remove items, and scroll to CrystalReportViewer.

Finally, to actually pass the information and show the form, you need some or all of the following code:

//// Basically here I'm just saying instantiate and somehow 
//// fill your dataset using Data Adapters, reading in XML, etc
dsMyTypedDataSet reportSource  = new dsMyTypedDataSet ();
reportSource.ReadXml(myFileName);
.
rptMyReportClass rpt = new rptMyReportClass();
rpt.SetDataSource(reportSource);
.
//// Set any parameters on the Crystal Report, if you set any up
rpt.SetParameterValue("MyParam", myValue); 
.
//// Get the form that you have the viewer on
frmReportViewer mdiReportViewer = new frmReportViewer();
.
//// FUDGE - either you're doing this on the viewer form, or
//// you've passed in "rpt" INTO the viewer form....
crystalReportViewer1.ReportSource = rpt;   //// this happens on the viewer form
.
.....
.
mdiReportViewer.Show();
.
//// FUDGE - something you can do on the viewer form if you want
crystalReportViewer1.ShowLastPage();
NumPages = crystalReportViewer1.GetCurrentPageNumber();
crystalReportViewer1.ShowFirstPage();
this.Text += String.Format(" : {0} Page{1}", NumPages, NumPages == 1 ? "" : "s");

This last bit was what I do to retrieve the number of pages and display it, else it doesn't know how many pages you have.

This is not perfect I'm sure, but please try it out and let me know what doesn't work so I can help you fill in the details.

Hi Susan!

Don’t worry darling! You are not the only one that hates this tedious, incomprehensible, infernal reporting tool! But, alas, here we are using it! I much prefer using SQL reporting, but not all of our clients can afford something that spectacular!

Thank you for replying to my post! I am sure to give your suggestion a try and I promise to keep you posted! I am currently using VCpp 6.0 for development at work, and the only time I have playing around with C# is in my private time! So… it might take me a little while to get back to you!

(On the side lines, are you from SA by any chance? Because I had this rather pleasant
instructor a while back (2002…2003? I think…) and I thought of trying to contact her and perhaps have a little something to drink!)

Thanks again

Willem Le Roux

Take your time, I hope the code sample, although a little rambling, will be of help. I saw that it was formatted really strangely, so I edited it, just for formatting.

No, but thanks for asking! I'll have a drink with you anyway! Oh, wait...I don't drink...drat.

Get motherboard serial number

4-Oct-05 0:03

Thanks for your help Susan!

I read your "edited" version and I will be playing around with Crystal tonight and again on Thursday! Like I said, I will keep you posted on how I do!

I will pop you some mail when I am in the states again... which might only be in 4-5years or so! I have a friend that stays in California somewhere! Then I will pay my dues in the form of a cup of hot chocolate and a muffin! (Or something along those lines)

Thanks again Susan!

Hi all,

Can anybody tell me how to get my motherboards serial number?

Any help would be great!

You can use WMI and the System.Managemnet namespace to get the serial number, IF AND ONLY IF your motherboard manufacturer supplies the WMI Management components to expose this information. Most don't. Check with your motherboard manufacturer for some kind of Management application that might install the required WMI classes.

Hi Dave!

Thanks for your reply and I will surly give this a shot, but I am looking for something a little more... pertinent shall I say...

I want to get the registration key of motherboards of various types, ages, makes ECT. ECT. ECT. It is going to be WAY too much effort trying to explain this "Installation of WMI Management components" scenario to every user!

Perhaps there is an easier way to go about this scenario? Perhaps a MAC address or something to this avail. If you can be of ANY assistance, please let me know!

Kind greetings

WMI is the only way you're going to do this. And, still, that's IF the motherboard manufacturer supplies it.

There's no standard method to get this and no "registration key" for motherboards. There's various components that make up a motherboard that are scattered throughout the device manager though. That's accessible through the Setup API functions. There's no .NET class that wraps it. How useful that information is depends on what you mean by "registration key" and what you want to do with it.

Hey sorry Dave!

Little typo! My brain was clearly broken that day! Work overload! I mean the "serial number" of the motherboard. Or the serial number for any component that is standard on any motherboard for that matter! Or a MAC address... Anything on the motherboard that is standard and unique! I will have a look through the device manager and toy around a bit!

Once again, sorry for my little typo! "Registration key" of the motherboard! That is stupid!

Thanks for your effort Dave! Really appreciate it! Will keep you posted!

Cheers!
