Sometimes coding in C#, you can't see the forest for the trees. I'm sure the answer is ridiculously simple, but it has me baffled.
On a windows form, the user clicks a toolstrip item which opend a dropdown list. The user clicks a selection, dropdown list disappears, and the selected item displays towards the top. To get rid of that displayed item, you have to click anywhere else on the form.
All I'm trying to do is when the user clicks their selection, close (wrong word?)down the display for that toolstrip item. (Act as if I clicked on a different portion of the form.)
Researching the problem, it's comforting to know that I am not the only one experiencing this problem. Other users experiencing the same problem seem to report "it doesn't work" to other offered solutions. I found an old post with an answer by a Microsoft employee stating, "It's by design." Well even so . . .

I have a strange problem with the configuration of an application written in c # winform.
I wrote a simple application that reads some records from a table in sql remote. in the App.config file I wrote the connection string and everything works.
I copied the bin folder on another pc and for error I renamed the configuration file <apptext> .exe.config in <apptext> .exe.conig
I run the application and the application rightly gave me error because it could not find the config file. I renamed the file correctly and everything works fine.
What happens: :mad:
randomly when I do a restart of the PC, I find myself in the bin folder
the configuration file wrong, what I had written the first time <apptext> .exe.conig
Can anyone tell me how to solve this problem?
is a week that I'm trying to understand what happens
by the time I solved by copying the configuration file at to the start of the application
but it's not good
the operating system is windows 7 and I just can not understand on what happens.
perhaps the first time, it was put configurator wrong in some cache
and when restart the PC overwrites the existing one.
I also removed the write permission to all users, including Administrator and System,
the problem remains
I can only assume that you are running this in Visual studio and regenerating the file when you restart your PC. Check all the settings in Visual Studio to see that it does not have a reference to the "wrong" name.
hi does anyone know how i can disable the animation which happens to a windows
form when the this.hide() is used?
I haven't tried it, but I guess it'd be the performance options of Windows. There's a setting in the system-page somewhere that let's the user decide between "cool" (animations, shades and stuff) and "fast" (no animation, no shades). Or to let Windows decide. AFAIK, it's a settting that would change the behaviour for ALL applications.
i am trying to do this without using thread.sleep.
Try clearing the .Controls collection and making the form 100% transparent. "Hide" it after that.

I need to develop a generic XMLEditor Form for an application (Windows Forms .Net 4.0).
The main concepts are:
- xsd definitions are known and stored as a resource
- form receives xml content string and the xsd name
- user must be able to edit (and add/delete) all of the xml attributes / values
Below is a sample of one of the xml content strings
<TechnicalCatalogInfo><Properties><Propertyid="1319"name="Some name"><![CDATA[Some text]]></Property><Propertyid="2715"name="Other name"><![CDATA[Some value]]></Property><Propertyid="2716"name="Another name"><![CDATA[One more value or text]]></Property></Properties></TechnicalCatalogInfo>
There are 3 or 4 different xml schemas and this form must be able to edit all of them.
Do you think that this can be done?
I am creating setup file with sql server database but i am facing an error...network elated error and i can't get the data from .mdf.deploy file...plz help me...it's my first project on windows based...
You mix up encoding and font. With modern .Net applications, you do not need to worry about non-ASCII-characters: .Net uses Unicode, and Malayalam is well defined there.
Probably, you are used to some encodings of the ISCII standards. Those ISCII encodings are 8bit encodings, and the text files written with such an encoding do not have the byte marks required to automatically find out the encoding. Consequently, when you show it in a text editor with the wrong "font" selected, it may look like Hindi/Devanagari or totally garbage. But by selecting the "font" of your text editor, you actually selected the encoding.
So just type your Malayalam text into the text boxes of your Windows forms application, it will work. Do not copy it from such an 8bit text file as described above!
I'm developing a MDI WinForm App using C#. I have a parent window with a splitContainer. Panel2 of the split container is used to used to display child forms while Panel1 is used for controls of the parent window. Child1 loads with parent form . However I have placed a button in Child1 that has to call child2 but I can't seem to find a way to close child1 and show child2 in panel2 of the Parent Split Container. I tried using the User Controls but I can't seem to pull through.. Please help.

I am working on windows application where the sensitive data in app.config file is encrypted i followed [^http://ozkary.blogspot.in/2013/03/encrypting-aspnet-application-settings.html] these to encrypt app.config file. It works very well in my machine. How do i deploy this?
I have a UserControl (call it SpiffyCombo) that consists of a ComboBox and a Label. The SpiffyCombo has a property (call it "Code") that has TwoWay databinding specified for it.
My Form has a BindingSource and an associated ErrorProvider. A property of the BindingSource's DataSource is bound to the Code property SpiffyCombo.
In a normal control, when an error occurs on the DataSource's property the error icon would appear next to the control. I can't get this to happen with SpiffyCombo. Is there some sort of Interface I need in the it or something I need to override to receive the error from the ErrorProvider? I want to control how the error is displayed within SpiffyCombo rather than have is show in the default location.
... i don't get any result on my form... if it need to assign something to the rdlc file or reportviwer other than the above code, or should i insert a dataset or anything other than the code.. if it need please help me it in programmatically....
I have one html document . I want to highlight text in html document but which text I want to highlight that is repeated text in html document . But I want to highlight only exact text according to my requirement then how can I determine the exact text which I want to highlight . Manually, I know that this text should have to highlight but how programmatically determine exact text to highlight between duplicates.
Please some one can help to me.
My exact scenario is giving below-
I want to explain my scenario I have some pdf and converting in epub file.After converting some text font name or font style missing then I have to compare with pdf and epub and highlight the exact text which font is missing.But because of duplicates I am not able to determine the text for highlight.
Thanks for your reply. Highlighting text is not a problem for me .My Problem is that while I am comparing epub to pdf , I am able to get text only not position of text. So I don't know the position of text and there is duplication of text which is making me uncomfortable to highlight text.
if I know position of text or there is not a duplication of text then it is easy to highlight.
I have a dotnet windows application in which i am using crystal reports, built using vs 2005, installed on a machine using click once setting. Till now the application is working fine. but when i am migrating my application from vs 2005 to 2010 and deploying it onto the test environment, at the time when client is opening the application through application shortcut ,the crystal report runtime for vs 2010 is not installing on the client machine. However i have mentioned it as a prerequisite and also the crystal report runtime setup is there in the Application deployed location.

Due to my current work, I need to display a plain image in a WinForms control (based on a map, but not from Bing / Google / other APIs) such as a JPEG or PNG in which I need to define/show points of interest. It will also be good to allow showing/hiding these layers of information (e.g. basic plain JPEG map in one layer, points of interest in another layer and dangerous points in a third layer) based on the user's criteria independently as well as allow clicking on these points.
In the past, I have performed such a similar work on a web environment by using OpenLayers, which provides a functionality (I think via a plugin/trunk) to work with plain images instead of retrieving the data from a devoted server.
But now, I'm a bit lost. I have been taking a look at SharpMap + GdalRasterLayer, but I have not been able to find any good tutorial to perform something similar to what I pretend. Maybe too much complicated for what I pretend, and of course not the target of these gis-based libraries.
I don't know of any 3rd. party library for this specific purpose, but, I think a lot of what you may do will depend on the nature of the whatever-objects you need to overlay on top of the map to define your "points of interest." Can you describe those objects further: are they icons ? graphic files ? Do they function as Controls, meaning: if you hover over them, click on them, etc., some action is performed ?
And, the solution will also depend on what facilities you provide for viewing the underlying map: will the user be able to pan, zoom ? I would guess you'd implement that which requires re-calculation of which overlay objects will appear, and where they will appear.
You can certainly create transparent Forms in WinForms and carefully position them over some base Form (or Panel, or other ContainerControl, in a base Form) that contains you map as a BackGroundImage. Those transparent Forms can, of course, have objects in them that are not transparent.
If you want to look further into doing this yourself in C#, then please post a more complete specification here.
good luck, Bill
