Im trying to open a minimized window,
How would i do this?
I tryed sendmessage(handle, 0x0112, ** , 0)
** = WM_SHOWWINDOW and WM_SETFOCUS both didnt work.
Help please.

On my wrong computer right now so don't have access to MSDN - but try WM_RESTOREWINDOW(or whatever it's called) or WM_MAXIMIZE - essentially Show Window is used when the window is hidden (different from minimized), and set focus just set's the focus, it won't restore it from it's minimized position.

[DllImport("user32.dll")]
private static extern bool ShowWindow(IntPtr winHandle, uint op);
public enum SW : uint {
HIDE = 0,
SHOWNORMAL = 1,
NORMAL = 1,
SHOWMINIMIZED = 2,
SHOWMAXIMIZED = 3,
MAXIMIZE = 3,
SHOWNOACTIVATE = 4,
SHOW = 5,
MINIMIZE = 6,
SHOWMINNOACTIVE = 7,
SHOWNA = 8,
RESTORE = 9,
SHOWDEFAULT = 10,
FORCEMINIMIZE = 11
}
...
ShowWindow(handle, (uint)SW.SHOW);
...

In your form you could do something like:
foreach (Control control in this.Controls)
{
if (control is TextBox)
control.Text = string.Empty;
}
|
|
|
|
|
<br />
foreach (Control c in this.controls)<br />
{<br />
if (c is TextBox)<br />
c.Text="";<br />
}<br />
|
|
|
|
|
foreach (Control c in this.Controls)
{
if (c is TextBox)
c.Text = new string('0', 0);
}
Sorry

Sigh. I feel like such a newb.
Ok, as the subject suggests I have a parent form that passes two values to a sub form. I want to edit the values on the sub form, and pass these updated values back to the parent form.
I can get the values to the sub form, but not back to the parent form... I just can't figure out how to make this happen. I get two errors:
Error 1 An object reference is required for the nonstatic field, method, or property 'WindowsApplication7.Form2.stAptUnitNum'
Error 2 An object reference is required for the nonstatic field, method, or property 'WindowsApplication7.Form2.stAddress'
I presume this means I am a rookie, er, I mean that I am doing something fundementally wrong, because to be honest even after googling this problem for over an hour I can't find an explanation that I understand. I thought making the two variables public on form2 would allow me to get their value when back to form1, but perhaps not.
On the main form:
<br />
private void fxn_reevaluate()<br />
{<br />
Form2 frm = new Form2(stAptUnitNum, stAddress);<br />
frm.ShowDialog();<br />
stAptUnitNum = Form2.stAptUnitNum;
stAddress = Form2.stAddress;
}
which then calls the sub form...
<br />
public Form2(string Address1, string Address2)<br />
{<br />
InitializeComponent();<br />
textBoxAddr1.Text = Address1;<br />
textBoxAddr2.Text = Address2;<br />
}<br />
<br />
public string stAptUnitNum;<br />
public string stAddress;<br />
<br />
private void btnSubmit_Click(object sender, EventArgs e)<br />
{<br />
stAptUnitNum = textBoxAddr1.Text.Trim();<br />
stAddress = textBoxAddr2.Text.Trim();<br />
this.Close();<br />
}<br />
Any help would be greatly appreciated.
Thanks!

You know, I really did read this article, and unless I am overlooking something, or failing to infer something, all I see here is pass value from parent to child (which I thankfully have working), update child from parent when child form is open (cool, but I am not there yet...) and passing values from children to child (sibling to sibling).
Am I overlooking something that shows how to get a value back from a child to the parent?
Thanks!

Yes, read the 'Sibling to Sibling' chapter.
"... This also demonstrates passing between the child and the parent."

You didn't declare the properties "stAptUnitNum" and "stAddress" as static. You must call them from the instance, like
frm.stAptUnitNum
frm.stAddress
instead of calling them on the class, like
Form2.stAptUnitNum
Form2.stAddress
Hope this helps.

I find the easiest way to do this is to change the subform's constructor and pass the control or variable or even the parent form in that.
|
|
|
|
|
There would be no need to pass public variables or the parent form through the constructor, since the child form has access through this.Parent

Hi. I'm having trouble using streamwriter on certain files because those files contain chinese characters. I can fix my problem, but only in a way that it'll work correctly for one or the other, but not both at the same time.
The main issue is that I need to write to files that do not contain chinese, and files that do contain chinese. These files are mixed together, and at times there can be 500+ files. The only way to tell them apart that I can think of is to check if the file uses a certain font.
The files that contain chinese characters display them using the SimSun font. The files that do not have chinese characters do not use the SimSun font.
How can I check a file to see if it uses a certain type of font? I just need pointed in the right direction. I've tried messing around with iTextSharp but it doesn't seem to be able to read files, just write to them.

Can't you check the encoding that the text file uses?
For example, Unicode(UTF-8) or Greek (ISO) or Arabic (DOS).
Or is the encoding all the same, and its just the font that provides the chinese characters?

I don't know how if it's possible.
All I could find on that was "EncodingInfo GetEncodings" or something, which I tried on a file containing chinese and a file that had just 1 character of english. They both returned about 30 codepages... all of which were exactly the same.

Hello everyone,
I have created a BHO using C#. The code works fine. I would like to detect mouse click on a particular bytton. The following is the SiteSet().
public class BHO : IObjectWithSite<br />
{<br />
private SHDocVw.WebBrowser webBrowser;<br />
private mshtml.HTMLDocument document;<br />
private mshtml.IHTMLDocument2 document2;<br />
private mshtml.HTMLElementEvents_Event events;<br />
<br />
public int SetSite(object site)<br />
{<br />
if (site != null)<br />
{<br />
webBrowser = (SHDocVw.WebBrowser)site;<br />
webBrowser.DocumentComplete += new SHDocVw.DWebBrowserEvents2_DocumentCompleteEventHandler(this.OnDocumentComplete);<br />
webBrowser.BeforeNavigate2 += new SHDocVw.DWebBrowserEvents2_BeforeNavigate2EventHandler(this.OnBeforeNavigate2);<br />
<br />
webBrowser.OnQuit += new SHDocVw.DWebBrowserEvents2_OnQuitEventHandler(this.OnQuit);<br />
webBrowser.NavigateComplete2 += new SHDocVw.DWebBrowserEvents2_NavigateComplete2EventHandler(this.NavigateComplete2); <br />
<br />
events.onclick += new mshtml.HTMLElementEvents_onclickEventHandler(this.OnElementMouseClick); <br />
<br />
}
for the OnElementMouseClick function I have the following.
public bool OnElementMouseClick()<br />
{<br />
MessageBox.Show("HelloWorld...");<br />
return true;<br />
}<br />
.<br />
.<br />
.<br />
.<br />
But nothing really happens! Am I wrong to think that the above code should give me HelloWorld message once a button is click?
Any information on this would be appriciated. Thank you very much.

Hello,
You should POST the entire message rather than posting one section of it. If I remeber correctly, I said "If my messages bother you so much I surly can stop and take my postings and problems to another forum.". That is if you wish to be fare, mate!
I still stand by my posting as I am not here to upset anyone.
By the way, didn't take your advise and managed to solve the problem. Hey, not all of use get Free MVP title! *wink*
Thank you for the reply.

Good for you. It is helpful to others to post the solution. If indeed you have solved it yourself. Perhaps someone with more experience just finished it for you. "wink*
