Hi I would like to trace my application and put all messages in a text file. I use Trace.TraceError(""); Trace.TraceInformation(""); Trace.TraceWarning(""); methods and when TraceSwitch level is set to for instance Error all messages are put in a file? Why? I thought when I set TraceSwitch (ts) to Error only TraceError messages would be sent. I would like to change only trace level and certain messages should autmatically be put in a file. Should I use Trace.WriteIf(ts.TraceError == true,"..."); What for if TraceError, TraceWarning etc.??? Ela

I do not want to filter these records but show them and to not show 0 but ' ' (blank space)

Hi I have one column which contains numeric data. If data is 0 I would like to display ''. How can I do that? Set any format? thanks for help Ela

Colin, When I was waiting for the answer I managed to do that in such a way you explained and it works! I can make a few changes after reading you responses. Many thanks for the explanation! ...very strange this singleton pattern :-) I had problems with saving settings but I created public method in singleton and called settings save method. Redards Ela

...but where to create the object of settings class?

Colin, Could you provide me with any example for such a specific project? I have one class e.g. public class MyAppSettings : ApplicationSettingsBase { [UserScopedSetting()] [DefaultSettingValueAttribute("true")] [global::System.Configuration.ApplicationScopedSettingAttribute()] public bool someProperty { get { return (bool)this["someProperty"]; } set { this["someProperty"] = value; } } Then I have to create a project dealing with the setting. I suppose it should contain class with static properties?? Could you give me an example? Thanks Ela

I think do not undrestand everything. I have many projects in solution and in almost all of them I need see global varialbes. Do I have to add a references to my "global" class with settings and create an object. There is something wrong. Ela

I understand I have to create an object of settings class in each project? Ela

If I knew I wouldn't ask. I thought there is an easier way to do with global settings in Framework 2.0. Ela

I thought so... Thanks for confirmation. I wondered if there is another way but I suppose not. Ela

Hi I have a big solution which contains many projects. I created a class public class MySettingClass:ApplicationSettingsBase which contains a few settings. I would like to have an access to these variables from almost all projects. How to do that in the most efficient way? When I want to use any setting variable I create an object public MySettingClass mySettings = new MySettingClass(); how to make it visible in all projects in solution? I do not want to pass any parameters (there would be too many changes). Do I have to create an object in each project? No sense. Thanks for help Ela

Such a life of developer :-)

What a fool I am. How couldn't I see such a beatifull protperty - just DataGridView. Many thanks for help. It is blinking now but there is something with gif. It is displayed as x - as it was no gif. However I think it is another problem. Many thanks one more time Ela

I created my own classes public class ImageCell : DataGridViewImageCell { public ImageCell(DataGridView grid) { this.grid = grid; } ........ private void animate(object o, EventArgs e) { DataGridView dgv = (DataGridView)grid; dgv.InvalidateCell(this); /// there is an error } } and public class ImageColumn : DataGridViewColumn { public ImageColumn(DataGridView dgv) { this.CellTemplate = new ImageCell(dgv); this.HeaderText = ""; this.Width = 25; this.Resizable = DataGridViewTriState.False; } } In my application when I have DataGridView I just add ImageColumn object as new column passing DataGridView object to the constructor: ImageColumn imgCol = new ImageColumn(m_DataGridView); m_DataGridView.Columns.Add(imgCol); I do not like to pass such a parameter to the constructor. However how to call InvalidateCell in ImageCell class? thanks Ela

I think I am near the solution however how to call a method of grid being on DataGridViewImageCell level?

There is a method grid.InvalidateCell however I cannot call it because I have to do it from DataGridViewImageCell level (form my own class). I described the problem above. Thanks for advice.

But DataGridViewImageCell does not have a Invalidate method.

I crated my own class inherited from DataGridViewImageCell. How can I call a method from parent object which is DataGridView? I passed a DataGridView parameter to constructor but when I call grid.InvalidateCell() I have a message "Object refrence not set to an instance of an object"

Hi Is it possible to force DataGridViewCell to repaint? Just refreshing it. Thanks Ela

Hi Does somebody know if it is possible to display animated gif in a cell in DataGridView and how to do it? Thanks Ela
