I need to run the code that I wrote in a Visual Studios project outside of the visual studios enviroment. Actually, I need to run it on a computer that does not have visual studios installed.

You compile your source code to an executable and typically create an installer package along with it. This is done in Visual Studio.

Could you point me to a good example of how to create an installer package?

Add a "Setup Project" to your solution as you would add any other project to your solution. And then go from there.

To find out more about deploying your application you should read MSDN as it gives you all the information. You'll find the information in the section titled Deploying Applications and Components[^]

You might want to pay particular attention to Walkthrough: Deploying a Windows Application[^] which gives you a step by step guide to creating an installation setup for your solution.

Does this help?

Form control event problems

yes, thank you.

I have a mdi child form that has two combo boxes and a data grid. The combo boxes are used to filter the records in the data grid.

The problem I am having is that I load the combo boxes from a dataset in the form load event. I also fill the datagrid from a dataset after loading the combo boxes. It looks to me that the combo box events (selectedvaluechanged) are running before everthing is loaded properly and causes loading errors. Both my combo boxes call a function to reload the datagrid. Am I loading the combo box values in the wrong event?

I hope that made sense.

Thanks,

JefferyS

Maybe in the selectedindex_changed event handler of the comboboxes , try this:

{
   if( this.combo_Box1.SelectedIndex > 0)
     {
       //Do filtering as required and
       //Reload Grid
     }
 }

Also, let me know if it actually works ( cross your fingers! ) Unsure | :~

Are you setting the selected index for comboboxes? That will cause the event to fire. Try setting the selected index after the datagrid is populated.

A quick solution would be to use a state variable. Set it to true once you have loaded your data and check it within your SelectedValueChanged before you do anything else within it.

Any way to test code effeciency?

Jefferys6-Aug-04 12:43

Thanks for all the suggestions. It seams that when you load the combo box (atleast with a dataset) it fires off the selectedItem and selectedvalue events, and maybe other combo box events.

The selectedIndex stayed at 0 all the time so the if(combobox.selectedindex > 0) did work, but sense I was using index 0 for "All" to not filter that category it wasn't going to work for me.

So after many cans of A&W Root Beer, I moved the lines that sets the events for both combo boxs under the last item in the form load event which was the loading of the datagrid. It seams to be working perfectly.

Thanks again for all the suggestions,

Hi, i'm working on improving the effeciency on a certain block of code and was wondering if any tools existed to see if i'm making positive contributions to the code.

You will have to analyse your algorhitm then. No point in attempting to make code faster with trial and error. Have a plan.

Setting Colum widths in a datagrid

I am programatically building a dataset that populates a datagrid. I need to then specfify the column widths for each column. However, the grid control ignores my input. I first tried setting the widths under TableStyles/GridColumnStyles. That was ignored so I figured it was because I wasn't populating the grid from a predefined datasource. So then I tried progammatically. Still nothing. Below is my code. The grid should only have one table in it. The grid populates correctly, it just doesn't format the widths of the columns. The dataset only returns 3 columns. Confused | :confused:

//get the data
dsResults = SqlHelper.ExecuteDataset(Conn,CommandType.StoredProcedure,"usp_GetSearchResultsSel",new SqlParameter("@Description", txtDescription.Text),new SqlParameter("@SearchParameters", cboSearchParam.SelectedText));

//populate the grid
dgResults.DataSource = dsResults.Tables[0].DefaultView;

//settings for grid
dgResults.TableStyles[0].GridColumnStyles[0].Width=200;
dgResults.TableStyles[0].GridColumnStyles[1].Width=50;
dgResults.TableStyles[0].GridColumnStyles[2].Width=100;
dgResults.ReadOnly=true;

I am assuming that its a winform application:

tabStyle1.MappingName = <mapping name="">

dgResults.TableStyles.Add(tabStyle1);

Yes this is a windows form. If I add in
dgResults.TableStyles[0].GridColumnStyles.Clear();
I get an 'index out of range' error unless I prepopulate the TableStyles of the grid prior. I took a look at the code at section 5.3.2 from
http://www.codeproject.com/csharp/PracticalGuideDataGrids4.asp#_Toc56951053.

This functions (if I set the dt equal to me dataset.Column), but it still doesn't modify the column widths. Dead | X|

Thanks for your quick reply.
