What i would like to do is to compare the AStartDate with both StartDate and EndDate which will be done in a DetailsView both insert and edit mode. This is to make sure AStartDate is within both those dates. (Same goes for AEndDate)
At first i though of extracting the StartDate and EndDate from the database and then make the comparison. But i am having problem because both StartDate and EndDate are data type "date" as follows:
Dim strProjDate As String
Using myConn3 As New SqlConnection(connString)
myConn3.Open()
Dim command3 As SqlCommand = myConn3.CreateCommand()
command3.Connection = myConn3
command3.CommandText = "SELECT StartDate FROM ProjDetails WHERE ProjID = @ProjID"
With command3.Parameters
.Add(New SqlParameter("@ProjID", TB_GenerateActID.Text))
End With
strProjDate = command3.ExecuteNonQuery()
TB_ProjStartDate.Text = strProjDate.ToString
End Using
The above code only displays "-7" in the TB_ProjStartDate textbox.
By the way, I am using Web Developer 2008, VB.net.
I am having trouble comparing two dates. One is captured from input, other one is predefined. Please see the code below: I enter this date in the textfield: 04-12-2001
Dim idatum As Date If Date.TryParseExact(aankoopdatumIDclm.Text, "dd-mm-yyyy", Nothing, System.Globalization.DateTimeStyles.None, idatum) = False Then 'idatum is true at this point...
Im trying to use the following SQL statement to find every row in Orderable Test List where there is not a row in Results Individual Tests that has a matching entry in the TESTHISCD column. When I run the page everything freezes up.
"SELECT [Orderable Test List].*, [Results Individual Tests].TESTHISCD FROM [Orderable Test List], [Results Individual Tests] WHERE [Orderable Test List].TESTHISCD <> [Results Individual Tests].TESTHISCD"
Since these table are on two different boxes and 2 different versions, I am getting error message that tables cant be compared because they have different schema's.Schema's are the same but they are on different machines and different servers. What is a work around it?
i am trying to compare four columns in two tables(both are in the same schema), table a has two columns for firstname and last name , table b has similar columns firstname and last name, i wish to compare both and if there are similarities, do nothing but if there are differencies, export or write them to a exception or error table.. not quite sure what if statement i should write or how to go about this.

I have a GridView Column "Gender". After displaying datagrid, I m selecting dropdown which is not in datagrid.
Dropdown list is in the same page. When I select dropdown Gender as male or female, I have to validate that Gender against GridView Column. If that Gender Exist in GridView, I have to display message.
I have a gridview, which on the row data bound method that inserts a row when comparing values on a particular field. If the two values are different, a new row is inserted, if not no row is inserted. This coding is working as a grouping gridview, and is working correctly. However, I have problem, and problem is counting the rows between each group, which I want to display in my blank row between each group, the value of which I am holding in a hiddenfield.
When I try to do it, the first group doesn't show the result, but is displayed on the next group. I am pretty sure that I am doing something wrong. My approach is that if the value between the last row and the existing row are different, then the value is one, on the next row data bound event, if the values are the same then the value is increased by one, else the value is one because it is a new group. Here is my code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { Table tbl = e.Row.Parent as Table; TableCell cell = new TableCell(); CheckBox chk = new CheckBox(); Label lbl2 = new Label(); HiddenField rowValue = new HiddenField(); if (e.Row.RowType == DataControlRowType.Header) { e.Row.Visible = false; } else { if (e.Row.RowType == DataControlRowType.DataRow) { Session["count"] = 1; Label lbl = (Label)e.Row.FindControl("lblValue"); string str1 = ((Label)(lbl)).Text; string prevStr= (string)Session["previousStr"]; if (prevStr== str1) { lbl.Visible = false;...................
I am dealing with dynamic fields in a for loop and now I need to retrieve the values that are being typed in the dynamic fields, any idea how can I do that? 2)also when I click the submit button, upon postback, the dynamic fields have gone missing, have been trying to slove that, but i did not, anyone knows how to deal with this? kinda urgent :x
3) and How do you compare the 2 dynamic fields? For eg: Im comparing the tbSch[i] to tbSch[i], so that the dates cannot be the same, am using a compare validator, but it throws me error that im comparing the same fields :) even though i change to ("tbSch" + i) for both, sorry Will provide my code snippet as follow :D tbNum is a textbox where user enter numbers and click generate
protected void btnGen_Click(object sender, EventArgs e) { for (int i = 0; i < Convert.ToInt32(tbNum.Text); i++) { // label and textbox needed Label lblSch = new Label(); TextBox tbSch = new TextBox(); Label lblWsGrp = new Label(); DropDownList ddlWsGrp = new DropDownList(); CompareValidator cvSame = new CompareValidator(); cvSame.ID = "cvSame" + i; cvSame.ErrorMessage = "Date cannot be the same"; cvSame.Operator = ValidationCompareOperator.NotEqual; cvSame.Type = ValidationDataType.Date; cvSame.Display = ValidatorDisplay.Dynamic; cvSame.EnableViewState = true; cvSame.ControlToValidate = (tbSch.ID);<<<<< what should be the value in here? cvSame.ControlToCompare = (tbSch.ID);<<<<<<<<<< and here? //schdule date lblSch.ID = "lblSch" + i; lblSch.Text = "Session Date : "; lblSch.EnableViewState = true; tbSch.ID = "tbSch" + i; tbSch.Width = 210; tbSch.Height = 27; tbSch.EnableViewState = true; //workshop grp lblWsGrp.ID = "lblwsgrp" + i; lblWsGrp.Text = "Workshop Group : "; lblWsGrp.EnableViewState = true; ddlWsGrp.ID = "ddlWsGrp" + i; ddlWsGrp.Height = 27; ddlWsGrp.Width = 210; ddlWsGrp.EnableViewState = true; ddlWsGrp.Items.Add("1"); ddlWsGrp.Items.Add("2"); //table to store data TableRow trow = new TableRow(); TableRow trow2 = new TableRow(); //row1 TableCell tc1 = new TableCell(); TableCell tc2 = new TableCell(); TableCell tc3 = new TableCell(); TableCell tc4 = new TableCell(); //row2 TableCell tc5 = new TableCell(); TableCell tc6 = new TableCell(); TableCell tc7 = new TableCell(); TableCell tc8 = new TableCell(); TableCelltc9 = new TableCell(); tc1.Controls.Add(lblSch); tc2.Controls.Add(tbSch); tc3.Controls.Add(lblWsGrp); tc4.Controls.Add(ddlWsGrp); tc5.Controls.Add(space); tc6.Controls.Add(CeSess); tc7.Controls.Add(space); tc8.Controls.Add(space); tc9.Controls.Add(cvSame) trow.Cells.Add(tc1); trow.Cells.Add(tc2); trow.Cells.Add(tc3); trow.Cells.Add(tc4); trow2.Cells.Add(tc5); trow2.Cells.Add(tc6); trow2.Cells.Add(tc7); trow2.Cells.Add(tc8); trow2.Cells.Add(t9); this.table3.Rows.Add(trow); this.table3.Rows.Add(trow2); } }
I have a date/time stored in a smalldatetime field (ms sql 2005) that i want to compare with the current time and receive a difference. If the difference is less than 30 minutes, do this....if more do that....
I have a form that contains a text box called "MyDate" in which the user enters a date. I have a table that contains records of which one of the fields in the record is a date field named "DateAvailable" (type is "datetime"). I want to compare the data in the text box to the "DateAvailable" field in record. How do I define my text box as a "datetime" field.
I need some pointers to start on this.We are building a time off application where three instances of a calendar control will be displayed ( prev - current and next month) now users can click on various dates accross all three instances and then a count of number of days should be diaplyed in the parent textbox.
To begin with this, i started with adding the dates clicked by the user in Calendar2_SelectionChanged method into a list<> so that i can get the all dates user clicked and then add it to calander's selected dates collection. But this throws an e" object reference not set" error.
Is there anyother way to get all the dates that user click onthe calendar( note the dates doesn't get highlighed so seleteddates doesnt work)does anyone has a good example for this.
I am using the following code to select data which appears between 2 dates:
string query = "SELECT (name, date) FROM date where tableinfo BETWEEN @date1 AND date2";[code]....
Now the above code is working fine. The only problem is that the date in the date column of the gridview is not in the proper format. What can i do in order to change the format of the date in the gridview. If the format of the date is changed in the databse itself I may be able to use the above SQL query.
I have a calendar where all the dates from my database are selected/highlighted.I have to use a repeater because else it won't work, but now i want a single calendar where multiple dates are selected, instead of a single calendar for every date in my database.My code:
once a user select an item from dropdownlist > Dates from DB are shown on calendar in pink color.
The problem now is when i want to select new dates the selected dates(in pink) become deselected .. I want them to stay selected so i can know which dates are already used .
