You're going to need a network communication between the PCs in the first place, with your code running on both PCs, in order to send voice between them. There's no way that I can write code on my computer, to send a dialog box to your computer, and return a result. Imagine if that were possible, how insecure the web would be ? You need to write code to pass the request, receive the request, show the message box, and send back the result. Code you wrote needs to be running on both computers.

Dear Experts,
I have two questions here, first, I wanna know how to make an autonumber on C sharp (textbox). I have selected max number from a field in the table but I do not know how to make the textbox becomes an autonumber (always +1 with the max number) when I load the form.
The second question, I have many forms in my small (homework) project. I open form2 from form1(form1 still actives), I add some text in form2 and I want to make form1 (ex: combox) refresh (vba calls requery) when I close form 2.
Thanks for reading the entire of this passage.

There is absolutely no way to do this automatically - you will have to write your own control. The only logical way I can see to do this is to have a column to show numbers, not add text to the control.

When your call to ShowDialog ends, you still have the dialog object and you can access it's properties. So, just expose the values you need, and grab and use them.

I am meeting a problem in sending SMS from Website, if you have code about it, send me please! thank for your helping! I hope you can help me, send me early, I am waiting it!

1 - we have an ASP.NET forum
2 - there is NO code to send an SMS. Instead, you need to find a local SMS provider ( don't forget to make sure it works where your client's server is, and not just where you are ). Any decent SMS provider will cost money. Free ones tend to disappear.

I was under the impression that SMSs were just emails. You could send an SMS to any phone by sending an email to the phone number at the service provider's SMS domain. Somebody got a hold of my cell phone number and kept sending me SMS emails and pictures. I had to go to Verizon and have them block all messages that originate from an email server and not a cell phone. What's interesting to me is that they have a checkbox option on the accounts to do just that.
Don't blame me. I voted for Chuck Norris.

That would be news to me. If that's the case, why are there commercial SMS services ? They generally provide a webservice you connect to, and then you pay for use.

That works for some providers, but not all. It used to work on Orange, but now your emails just bounce

Hi everyone, I am trying to change windows title text programatically, but do not know how.
I am working on win form app. I want to change for example Form1 to X. How do I do it? not
manually through propertry window. application run time I want to change it.
thanks
|
|

|

In the necessary place in your Form1's code:
Text = "X";
this.Text = "X"; This is very basic stuff. You really should study a book and/or some online getting started tutorials before asking questions in a forum. We don't mind helping when you're stuck - but we're not pre-'coding school' teachers.

thanks dave ,
I could not figur it out anyway. do not know why.
as you know it can be trivial but tricky.
|
|
|
|
|
Well the property window tells you the property name, you know your Forms name, putting 2 and 2 together shouldn't be tricky. I would take Dave's advice and get a beginners book.

public static void getyn(ref Form org_form)
{
org_form.Enabled=False;
}
The simple method above illustrates how I can disable a form that has been instantiated elsewhere, using a reference parameter. If I instantiate a form "test_this", and in that code, I call this method above passing "test_this", this works. But now I want to access "test_this" or "org_form" (to me, they are the same for this issue) in another method (ie. org_form.Enabled=True;), such as within a button click event of another form. In that code, I do not know what name was used to instantiate the form. My thought would be to somehow create some public reference or pointer in this "getyn" method so that I can access this elsewhere. There must be some way to make "org_form" available/public so it can be accessed in other methods?

First of all, there is no need for the ref for your parameter. Form is a class and therefore passed by reference anyway.
Secondly, passing Forms around and making instances of them public to external classes is a BAD idea.
Ask yourself - what object owns what?
1. If the Form is owned by the other object, then when it creates the form it can store a reference to it for later use.
2. If the Form owns the other object , then the other object should raise events which the Form subscribes to after instanciation of the object.
3. If there is no direct relationship between the Form and the other object then I would recommend a 'manager' class that can instanciate the form and the other object, store references to them and subscribe to their events so it can handle communication between them.
Edit: A little diagram to show what I mean:

Pleaseeee...help me!!i'm so confused find the right code to copy my image from my picturebox,to new page at Adobe Photoshop.And i want the picture that i move with original type of files.(ex.if the image in .png,then when i drag to photoshop,it still in .eps format.)
i don't know how to do it.Can anyone help me solve this problem?i need it very much.thx

You have no control whatsoever over what Photoshop does when you drag and drop a picture. However, the picture will be a bitmap in memory, Photoshop is just trying to save in it's default format when you try to save a file.

OK, so I have my TabControl, which is by the way owner drawn, and I have my TabPages. I want to make the user able to, when a TabPage is clicked and the mouse is moving, move the contents of the TabPage. Now, the moving is working, but my MouseMove event is firing even though my mouse isn't moving!
This is the code:
protected override void OnMouseMove(MouseEventArgs e)
{
base.OnMouseMove(e);
bool foundItem = false;
int index = -1;
foreach (TabPage page in this.TabPages)
{
index++;
if (this.GetTabRect(index).Contains
(e.Location) == true)
{
_hoverIndex = index;
this.Invalidate();
foundItem = true;
if (this.TabMouseEnter != null)
{
TabMouseEventArgs tabArgs = new TabMouseEventArgs();
tabArgs.TabPage = page;
this.TabMouseEnter(this, tabArgs);
}
}
else if (foundItem == false)
{
_hoverIndex = -1;
this.Invalidate();
if (this.TabMouseLeave != null)
{
TabMouseEventArgs tabArgs = new TabMouseEventArgs();
tabArgs.TabPage = page;
this.TabMouseLeave(this, tabArgs);
}
}
}
if (e.Button == MouseButtons.Left)
{
if (_hoverIndex != -1)
{
DockStyle dockStyle = this.DockPanel.Dock;
this.DockPanel.DockPane.HideDockRectangles();
DockForm dockForm = new DockForm();
DockPanel dockPanel = this.DockPanel;
this.DockPanel.DockPane.Controls.Remove(dockPanel);
dockPanel.Dock = DockStyle.Fill;
dockForm.Location = Cursor.Position;
dockForm.Controls.Add(dockPanel);
dockForm.Renderer = this.Renderer;
dockForm.Show();
this.DockPanel.DockForm = dockForm;
List<TabPage> removePages = new List<TabPage>();
foreach (TabPage page in this.TabPages)
{
if (page != this.DockPanel.MainTabPage)
removePages.Add(page);
}
foreach (TabPage page in removePages)
{
foreach (Control control in page.Controls)
{
if (control is DockContainer)
{
DockContainer container = control as DockContainer;
this.DockPanel.DockPane.CreatePanel(container.Form, dockStyle);
this.TabPages.Remove(page);
}
}
}
}
}
}
This is really the only related code. Any ideas?

I can't believe I'm doing this...
In my job, I have to digitally sign .MSI files before deployment. Previously, this was done using the CAPICOM 2.1 library and a manual wizard-based process to sign the .MSI.
Seeing an opportunity for process improvement, I scripted this process into a drag-and-drop operation where you just drop the .MSI file on the script and it would use the CAPICOM COM objects to find the appropriate code-signing certificate and sign the file for you, baking the signed hash into the file. When you went out to Explorer, you get the properties on the file and click the Digital Signatures tab, whaalaa, you can see the signature!
This process worked great under Windows XP...
Now, move to Windows 7 (we're skipping Vista! ). CAPICOM is no longer in the Windows SDK and is no longer supported as it is offically deprecated by MS. MS says that the same functionality CAPICOM provided can be cobbled together using managed code and the .NET Framework.
I've tried to get CAPICOM to work under Windows 7, but I haven't been able to get any of the COM objects to instantiate. So, now I'm trying to poke around the classes under the System.Security.Cryptography namespace and put together a process to digitally sign an .MSI file (or any other file for that matter,) but do it the with the signature in the file. Having a seperate signed hash in a p7s file does me no good. It must be baked into the .MSI just like the old CAPICOM process did it.
Anyone got any clues or research points to rebuilding this process in managed code? Which classes am I looking at?? I can see the the X509 certificates using the classes in the System.Security.Cryptography.X509Certificates namespace, but can't seem to piece together the signing process. What am I missing?

For the offical word on CAPICOM support under Windows 7, read this[^].
After about 90 minutes of excersizing my Google Fu, I finally found this[^], which states that I'll have to resort to P/Invoking the Win32 functions I need to get the files signed with an embedded signature.  Yuk! Why couldn't they provide an entirely managed solution to replace CAPICOM?!
