Hi everyone,
I'm having some serious issues with the Windows ComboBox control. I'm using it inside a 3rd party wizard control (which I found here on CP) and when the page of the wizard where this ComboBox is is loaded, it gets populated with items - using the following code:
<br />
if(md.Topics.Count>0)<br />
{<br />
this.comboBoxTopicsDel.ValueMember="TopicID";<br />
this.comboBoxTopicsDel.DisplayMember="TopicTitle";<br />
this.comboBoxTopicsDel.DataSource=md.Topics;<br />
}<br />
else<br />
{<br />
this.comboBoxTopicsDel.DataSource=null;<br />
}<br />
This works fine everytime the page containing the ComboBox loads, until the moment when an item is deleted from the Topics ArrayList. After that, the ComboBox will only show TopicData for each item, even if its DisplayMember and ValueMember are set correctly.
Am I doing something stupid? What am I supposed to do before re-binding the ComboBox to ist data source when this happens?
Thanks in advance  (insert a lot of clueless smileys here)

One of my friends suggested to do BindingContext[...].SuspendBinding(); before and BindingContext[...].ResumeBinding after the item is removed from the md.Topics ArrayList and it seems to work fine now!

Hy everyone!
What I want to do is trying to check the language of Outlook (I don't mean the language Outlook had been written in; I do mean the language of the menues, promts etc.).
Meaning I do want to send a kind of request to Outlook telling it's language, so I am able to do some internationalisation. Because I do not want my code depend on "a special language", meaning my application should check the language and if it is English, it should use the "English style", if it is German it should use the "German style", if French the "French style" etc. (style means the keywords for example or menu items etc.)
So if anyone of you knew how to check this in C# it would help me a lot!
Thanks!
Stephan.

You do not need to do it this way. You can write you application so it is localized in different languages without the reliance of Outlook. You need to look at the ResourceManager class here[^]. The ResourceManager will extract resources from your assembly. You will specify the CultureInfo based on the current thread, this is what tells the ResourceManager which *language* (i.e., the culture) is used and to extract the appropriate resources. A simple example is as follows:
ResourceManager rsmgr = new ResourceManager("entries", Assembly.GetExecutingAssembly());
CultureInfo ci = Thread.CurrentThread.CurrentCulture;
string msg = rsmgr.GetString("title", ci);

am I also able to check if Outlook is English and the rest of the system is lets say in German?
Because my application should depend on the "language of Outlook" which could differ from the rest of the program languages installed on the system (like described above).
Because as far as I know, the CultureInfo only checks which selection you did in Windows control panel, but it does not check, if you installed a different Outlook version in a different language, or does it?
Because I do also have to be prepared for things like that (difference between cultursetting and Outlook language e.g.).
That's why my first intention was directly checking the language of Outlook.

If for some reason you want to specifically rely on Outlook being installed you can check the registry for an Outlook hive (mine was HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook), you will find a REG_DWORD entry titled LastUILanguage. On my machine the value was 0x00000409, the integer value is 1033 of that which identifies the language as "English - United States" per the Locale ID (LCID) Chart[^].

You can do this by using COM interfaces exposed by OutLook.
For example if you use Visual Basic, Visual Basic .NET, C# you can check the language of OutLook by referencing the Type Library of OutLook and getting the value of
Application.LanguageSettings.LanguageID(msoLanguageIDUI) (VB6.0 and VBA in OutLook syntax )
This is a Long data type representing the Language ID. For example 1033 is for English language.
You can see all of the values for language ID in “Object browser” in Visual Basic editor by searching for LanguageID.
In C# syntax is:
Outlook.Application ptlApp=new Outlook.ApplicationClass() ;
System.Diagnostics.Debug.WriteLine(ptlApp.LanguageSettings.get_LanguageID( Microsoft.Office.Core.MsoAppLanguageID.msoLanguageIDUI).ToString());
If You use VC++ you can use #import directive for importing of Type library of OutLook but the syntax will look different.

This information is stored in the registry, you shouldn't include a typelib or the Primary Interop Assemblies if that's the only reason you are using them. No reason to make you application weigh more than it needs to be. See my post above for further information.

Thanks for the hints, I will have to have a look, if the registry is accessible in every account here, because there are some very restricted ones, but as far as I do know this shouldn't be a problem reading the registry, does it?
I just wondered if I it is possible to do some further steps, like trying to "talk" to special fields in Outlook (see my other thread importing Outlook data[^]). Because my aim is to read some data out of Outlook contacts, which I do drag&drop into my application. But my application should be able to do this without being dependend on the language. So for example if the user chose the business number to be draged&dropped then there shouldn't be any difference no matter if the language was German, English or French. So my first idea was to access the contacts or the drag&drop item respectively and adress the datafield. But then I realized the drag&drop object is an array of strings and there are just those fields which have been filled in.
So last idea is to check the fieldnames via the Outlook object. Because then I do know what to match it with.
E.g. if my application checked English to be the language and I do want to drag&drop the business number, then I do want to read the fieldname which I have to parse out of my string array. Because then I do not have to store the fieldnames for all of the supported languages e.g. in a file or anywhere else. But I am not sure if I am just able to read data items and not the headers meaning all fieldnames.
So do you have any idea if I had to carry the fieldinfos for every language with me or if I am able to check the fieldnames because then I could switch from just checking the language to checking the fieldnames and so knowing which "token" to look for in my stringarray.
Stephan.

Hi, I saw your post above and you are absolutely right that reading the value LastUILanguage from registry is more efficient and it is not connected with increasing of weight of the application.

One of the features stopping us migrating to C# from VC++ is the limited windows form styles. In a VC++ dialog box we can set the dialog box to have no borders and pop-up style.
I cant seem to find a way setting a windowsform to have no border in C#/MC++, I wonder if this is possible at all?
many thanks

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
You can set it through the properties or in code as above, valid styles are:
Fixed3D :A fixed, three-dimensional border.
FixedDialog : A thick, fixed dialog-style border.
FixedSingle : A fixed, single line border.
FixedToolWindow : A tool window border that is not resizable.
None " No border.
Sizable : A resizable border. (Default)
SizableToolWindow : A resizable tool window border.

Hi Gurus,
I got some kind of unusual program to do...
I am viewing a web page in Internet Explorer 6.0, and I got a flash object in that page. So, I want to ask you if it's technically possible to write program that will send onclick message to the Internet Explorer window? And if it does can you give me some help how to do this thing, please. Or maybe some links would be helpful too...Thanx.

Yes, you can P/Invoke SendMessage and pass the BN_CLICKED message. You will need to the HWND (handle) of the button itself for the SendMessage call as well. You can programmatically iterate through each window using FindWindow. Spy++ may also be of some help to you depending on specific implementation.

Thanx for your answer...Could you please give me some links or code samples
of SendMessage, HWND and FindWindow usage? Or some articles would be helpfull...

Reading MSDN[^] will be very helpful. In particular, SendMessage is documented here[^], however because it is a native method, you will need to use P/Invoke to gain access to it. Reading about the DllImportAttribute Class[^] will be helpful. Also, you can read about P/Invoke here[^]. In .NET, a HWND or handle is of data type IntPtr. The SendMessage declaration should look like this:
[DllImport("user32.dll")]
static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam,
IntPtr lParam);

Hi,
I have an application for which I must create a Setup package. The package allows the user to enter some information in a text box (during the installation). I have used Textboxes(A) for this purpose. The textbox must contain a default value when presented to the user during the installation. This default value must be set dynamically. Is there some way this can be done... maybe the Setup Package reading an ini file and putting the value from the file into the text box during the installation?
I don't know if and how ini files can be read during the installation.

You set the EditNProperty to a property name, typically upper case (so it can be changed on the command-line as a protected property, though, IIRC, VS.NET doesn't use this (it's very limited in functionality when it comes to Windows Installer packages). You can set the initial value using EditNValue.
After compiling the MSI package, you can also use Orca from the Windows Installer SDK (go to http://msdn.microsoft.com/platformsdk[^] to download it, though Orca is a separate install within the downloaded files; in the bin directory, install Orca.msi) to add that same property name to the Property table with the initial value.

I already have used the Edit1Property and have set it to "URL". What I need is to be able to fill the Edit1Value dynamically, read from a text file maybe, and be displayed to the user.

You have to write a custom action for that, and writing a .NET Installer class derivative won't work. You must write a native custom action (see the Windows Installer SDK for details), and VS.NET does not support that.
It can be read from the command-line, though, if you use something like this:
msiexec.exe /i MyPackage.msi URL=http: I suggest you read through the Windows Installer SDK.
The VS.NET Windows Installer project is very limited, as I mentioned before. Trust me - I've been working with Windows Installer since 1.0 beta many years ago and have been a consultant for numerous companies for Windows Installer-related development. VS.NET's Installer project is meant to be quick and simple and does not expose a UI for a majority of what's possible.

hai there,
i need a small openion from your side. i have one project (ERP for Education Institution) in VB. the reprts and database are created by power builder and sybase.
Right now , i planned to upgrade it to dotnet. Before that let me say one thing. I have no intension to update or upgrade my reports and database. i am only to upgrade other phases of this project.
1. According to you, which dotnet language is most perfect match for this senario.
2. Upto how much extend i can make it updated using C#.net ?
3. is there any tutorial or urls that will help me to kick start this upgradation job ?
i am confort in C# than vb.net.
thanks

No. Your rewriting an application. It's up to you to figure out the requirements, design and build. You already have a tempate to work from if you have the PowerBuilder source.

I use MDI form in my C# project,
each MDI child form has a PictureBox on it,
When I load my saved project,
I use
myPicture.PictureBox.Image = Image.FromFile(path);
to set the image show on PictureBox.
But in my project sometimes I need to insert a new Page,
so I write
<br />
for(int i=Page_number-1; i>IntSelectPage; i--)<br />
{<br />
((MyInkPicture)myAL[i]).PictureBox.Image = ((MyInkPicture)myAL[i-1]).PictureBox.Image;<br />
} <br />
to show the correct image of each page,
Now there is a big problem,
When I want to save my changes,
<br />
PictureBox.Image.Save(savepath,System.Drawing.Imaging.ImageFormat.Bmp);<br />
for example,
because original PictureBox[2]'s image now is PictureBox[3]'s image,
if I want to save image by "Picture2.bmp",
it would tell me "Picture2.bmp" is in use...I can't overwrite it!!
Can anyone tell me how to load a picture form a set file path,
and if the image changes, I can overwrite it...??
Thanks a lot !!

Clone the original image then dispose it so that you have a copy of the image, not an image from a file (which uses an open file handle, leaving the file in use):
using (Image img = Image.FromFile(path))
myPicture.PictureBox.Image = (Image)img.Clone(); The using statement here makes sure that the object is disposed when the block is complete, even in cases when an exception is thrown.
Also - just a suggestion - I'd recommend you encapsulate myPicture.PictureBox.Image, exposing the Image property on your class by defining it like so:
public System.Drawing.Image Image
{
get { return PictureBox.Image; }
set { PictureBox.Image = value; }
}This ensures that callers can directly modify your PictureBox control. This makes for a better object-oriented design.

I add two TextBoxes snd a checkbox to a panel, each time I click on the add button. Each have a unique name. I can add them fine, I need to remove them according to the checkbox's checked property. I first need to know whether a checkbox is selected, then I need to traverse all the checkboxes and if they are seleted, I need to remove the corresponding texboxes.
I use:
if(this.pnl1.Controls.Contains(CheckBox))
{
// how to check each checkbox
}
Help!
